charlottesweb英文版篇章名称
charlottesweb英文版篇章名称The chapters of Charlotte's Web, a timeless classic by E.B. White, are a tapestry of friendship, love, andsacrifice woven together with the threads of a spider's web. Each chapter title, from "Wilbur" to "The Last Day," serves as a beacon, guiding the reader through the emotional landscape of a barnyard where ordinary animals become extraordinary friends.The journey begins with "Wilbur," introducing us to a runt of a pig who, despite his humble beginnings, is destined for greatness. His fate is intertwined with the appearance of Charlotte, a wise and compassionate spider, who sees beyond Wilbur's physical form and recognizes his inherent worth. Charlotte's web becomes not only a means of communication but a symbol of their deep bond.As the story unfolds, chapters like "Escape" and "Lurvy" highlight the dangers Wilbur faces and the lengths Charlotte and her friends go to protect him. The tension builds as Wilbur's fate hangs in the balance, and thereader is drawn into the heart of the story, feeling the same sense of urgency and fear as the characters.The chapters "Summer Days" and "Wilbur's Boast" offer moments of levity and joy, reminding us of the simple pleasures of life in the barnyard. These lighter moments are balanced with heavier themes of loss and change, as seen in chapters like "Bad News" and "Winter's Coming."The climax of the story arrives in chapters like "The Miracle" and "The Cricket's Song," where Charlotte's web reaches its full potential, saving Wilbur from a certain fate. These chapters are filled with hope and wonder, leaving the reader in awe of Charlotte's ingenuity and selflessness.However, the story does not end with a happy ending. The final chapters, "The Last Day" and "Goodbye!" bring a sense of closure but also a bittersweet farewell.Charlotte's sacrifice is remembered and honored, leaving a lasting impact on all who knew her.Throughout Charlotte's Web, each chapter title serves as a stepping stone, guiding us through the emotional and thematic journey of the story. It is a testament to the power of friendship, love, and sacrifice, reminding us thateven the smallest of creatures can have a profound impacton our lives.**夏洛的网中的友谊与牺牲之旅**E.B.怀特的不朽经典《夏洛的网》中的每个篇章，都是一幅由友谊、爱与牺牲编织而成的织锦。

The selection of pressure gauge should be made in accordance with the rules set out in EN 837-2. A failure resulting in injury or damage may be caused by excessive overpressure, excessive vibration or pressure pulsation, excessive instrument temperature, corrosion of the pressure containing parts, or other misuse. Consult the manufacturer before installing if there are any questions or concerns.2.1.1 O verpressurePressure spikes in excess of the rated overpressure capability of the transducer may cause irreversible electrical and/or mechanical damage to the pressure measuring and containing elements.Fluid hammer and surges can destroy any pressure transducer and must always be avoided. A pressure snubber should be installed to eliminate the damaging hammer effects. Fluid hammer occurs when a liquid flow is sud denly stopped, as with quick closing solenoid valves. Surges occur when flow is suddenly begun, as when a pump is turned on at full power or a valve is quickly opened.Liquid surges are particularly damaging to pressure transducers if the pipe is originally empty. To avoid damaging surges, fluid lines should remain full (if possible), pumps should be brought up to power slowly, and valves opened slowly. To avoid damage from both fluid hammer and surges, a surge chamber should be installed.Symptoms of fluid hammer and surge's damaging effects:• Pressure transducer exhibits an output at zero pressure (large zero offset).• Pressure transducer output remains constant regardless of pressure• In severe cases, there will be no output.2.1.2 FreezingProhibit freezing of media in pressure port. Unit should be drained (mount in vertical position to prevent possible overpressure damage from frozen media.2.1.3 Static electrical chargesAny electrical device may be susceptible to damage when exposed to static electrical charges. To avoid damage to the transducer observe the following:• Operator/installer should follow the proper ESD (electrostatic discharge) protection procedures before handling the pressure transducer components.• Ground the body of the device BEFORE making any electrical connections• When disconnecting, remove the ground LAST!The shield and drain wire in the cable (if supplied) is not connected to the transducer body, and is not asuitable ground.2.2 Use in accordance with intended purposeThe devices are only to be used for the intended purpose as described by the manufacturer.The devices are used for direct display of overpressures, vacuum and compound pressure and for transmission of overpressures, vacuum and compound pressure into a standard electrical output signal.For each use scenario, the corresponding set-up regulations must be respected.The usage in explosion risk areas is not allowed.2.3 Operator’s responsibilitySafety instructions for proper operation of the device must be respected. They are to be provided by the operator for use by the respective personnel for installation, servicing, inspection and operation. Risks from electrical energy and from the released energy of the medium, from escaping media and from improper connection of the device must be eliminated. The details for this are to be found in the corresponding applicable set of regulations, such as DIN EN, UVV (accident prevention regulations) and in sector-specific instances of use (DVWG, Ex-. GL, etc.) the VDE guidelines and the regulations supplied by local utilities companies.The device must be taken out of service and secured against inadvertently being restarted, if the presumption is that risk-free operation is no longer possible (see Chapter 9: Faults).Field Modification or other alterations to the instrument are not permitted and will void the warranty. This also applies to installation of spare parts. Possible conversations or alterations may only be carried out by the manufacturer.The operational safety of the device is only guaranteed where it is used for its intended purpose. The specification of the device must be adapted to the medium used in the plant. The limit values indicated in the technical data must not be exceeded.The safety information detailed in this Operating Manual, existing national regulations for accident prevention, and the operator’s internal regulations regarding working, operations and safety must be respected.The operator is responsible for all specified servicing, inspection and installation works being carried out by authorized and qualified specialists.2.4 Staff qualifications (target group assessment)The device may only be installed and started up by specialist staff familiar with installation, start-up and operation of the product.Specialist staff is defined as those individuals capable of assessing the work assigned to them on the basis of their specialist training, knowledge and experience of the relevant standards, and can identify possible risks.2.5 Signs/Safety markingsThe pressure gauge and packaging carry markings detailing the article number, measurement range and manufacturer. The pressure gauge can be provided with additional signs and safety markings advising on special conditions:⏹Advice on calibration⏹Safety marking pursuant to EN 837-1⏹Oil-can deleted (if used for oxygen service)⏹Silicone-free (for use in the automotive industry)2.6 Safety equipmentThe window of model T5500E uses multi-layer safety glass.This device has internal transient and reverse power protection.2.7 Environmental protectionThis device does not contain any environmental critical components.3 Technical dataThe detailed technical information can be found in the documents in the Appendix, Chapter 11.4 Labeling on the deviceThe label with the serial number and type designation is located on the outside of the housing. The materials identifier is encoded in the type designation.5 Construction and function5.1 Overview1 Socket and instrument connection2 Electrical termination3 Dial4 Pointer5 Cap with access to PCB6 Vent valve7 Case8 Bayonet ring5.2 Description of functionThe sensing element, a bourdon tube (C-form or helical) that is welded to the socket, will be exposed from inside with pressure. Under pressure the elastic tube is deflecting against the zero position. This deflection is proportional to the adjacent pressure. The movement transfers the deflection to the pointer.The display of the measured value is provided on a 270° scale (dial arc).The sensing element, a thin film pressure sensor that is welded to the socket, will be exposed from outside with pressure. Under pressure the elastic diaphragm is deflecting against the zero position. This deflection is measured by resistors of a Wheatstone bridge located at the back side of diaphragm. The PCB transfers the output signal of the sensing element into a standard electric output signal.5.3 Description of components5.3.1 Scale with pointerThe pressure gauge is equipped with a dial face and pointer pursuant to EN 837-1, nominal size 100 mm (4”).5.3.2 Instrument connectionThe instrument connection is located on the bottom side of the pressure gauge and is a ¼” or ½” Male NPT threaded pressure connection.5.3.3 Vent valveThe vent valve for the housing is located on the top side. If the nipple is pulled out, the housing is ventilated and the pressure which has built up in the housing due to the influence of temperature is discharged. With the valve closed, protection class IP 65 is achieved.5.3.4 Thin film sensing elementThe pressure transmitter incorporates polysilicon thin film technology. Modern low-pressure chemical vapor deposition methods provide simple, stable molecular bonds between the metal diaphragm and a polysilicon strain gage bridge. There are no epoxies or bonding agents to contribute to signal instability or drift. The integral metal diaphragm and polysilicon bridge are virtually unaffected by shock, vibration or mounting.5.3.5 Printed circuit boardThe PCB provides the signal conditioning and is equipped with pots for zero and span adjustment.5.3.6 Electrical terminationThe electrical termination is provided with standardized termination plug.5.4 AccessoriesPlease contact the manufacturer regarding special tools and accessories.6 Transport6.1 SafetyThe pressure gauge should be protected against the effects of knocks and impacts. The device should only be transported in the packaging provided to prevent damage. The device should only be transported in a clean condition (free of residues of measuring media).6.2 Transport inspectionDelivery should be checked for completeness and potential damage due to transport. In the event damage, delivery must not be accepted, or only accepted subject to reservation of the scope of the damage being recorded.6.3 StorageThe pressure gauge must be stored in dry, clean conditions, within a temperature range of -40/185 °F (-40/+85 °C), protected against direct exposure to sunlight and protected against impact damage.7 Assembly/Installation7.1 SafetyTo ensure safe working during installation and servicing, suitable shut-off valves must be installed in the plant (see 5.4 Accessories) prior to enabling the device:⏹Relieve pressure to remove from operation;⏹Disconnect power for repair or inspection within the relevant plant;⏹Or to enable function tests of the device to be performed “on site”.During preparation to mount/install the gauge, the plant must be protected against being switched back on.7.2 Preparations (requirements for the installation location)⏹ A check on suitability of the device for the medium to be measured, the scope of the measurement range and ofthe protection against special conditions such as vibrations, pulsations and pressure spikes.⏹ A bracket must be installed to support the pressure gauge if the metering pipe is not able to provide adequatesupport.⏹The installation location should be selected where no personnel operate behind the rear of the pressure gauge.7.3 Mounting/Installation7.3.1 Process connectionAs standard, the device is equipped to be pipe mounted with a pressure connection shank pursuant to DIN EN 837-1. The device is calibrated ex-works for vertical installation.⏹Connection to be undertaken by authorized and qualified specialist staff only.⏹Use only with the mechanical process connection provided – regarding the configuration, see order code on thedevice type label, with a matching threaded seal.⏹When connecting the device, the pipes must be depressurized.⏹The pressure metering pipe must be laid inclined in such a way that, for example, for measurements of fluids noair pockets can form, and for measurements of gases no water pockets. If the necessary incline is not achieved, then at suitable points water separators or air separators must be installed.⏹The pressure metering pipe must be kept as short as possible and laid without sharp bends, to avoid theoccurrence of irritating delays.⏹With liquid measurement media, the pressurized connection pipe must be degassed, since any gas bubbleinclusions result in measurement error.⏹If water is used as the measurement medium, the device must be frost-protected.Safety notice: Only mount using the correct open-jawed wrench, and do not twist the device itself.G ¼ B, G ½ B1. Pressure connection2. Gasket DIN 16258Other parallel threads 1. Pressure connection 2. Gasket (USIT)7.3.2 Electrical connection⏹ Connection to be undertaken by authorized and qualified specialist staff only.⏹ The electrical connection of the device is to be undertaken in accordance with the relevant regulations of the VDEand the regulations supplied by the local utilities company.⏹ Disconnect the plant from the mains supply before wiring electrical connections.⏹ Power supply to be provided is 12-30 VDC⏹ Maximum loop resistance fo r 4 ... 20 mA: ≤ (UB – 9,5 V) / 0,02 A⏹ For minimum noise susceptibility, avoid running the transducer’s cable in a conduit that contains high current ACpower cables. Where possible avoid running the cable near inductive equipment.⏹ Units with shielded cable electrical termination, connect the drain wire to the guard terminal on the read out deviceor measuring instrument, if available. In all other cases connect to the ground or to the power supply negative terminal.Wiring Diagrams:7.4 Starting upThe precondition for start-up is proper installation of all electrical feed lines and metering pipes. All connecting lines must be laid such that no mechanical forces can act on the device.Before start-up, the seal on the pressurized connection line must be checked.7.4.1 Zero point adjustment for pressure gaugeThe pressure gauges are supplied calibrated ex -works, so that as a rule there is no need for calibration works at the installation point.For devices with Micrometer pointer (see. order code), zero point adjustment on site is possible. For this, proceed asfollows:⏹ Depressurize the pressure metering pipe.⏹ Open the bayonet ring and remove ring and window.⏹ Hold the pointer in place while turning the screw, until thepointer (after releasing again) has the correct position.⏹ Close the case again and pay attention to correct fit ofwindow, gasket and bayonet ring.7.4.2 Zero point adjustment for transmitterWhile Zero adjustment is not normally necessary, it may be desirable to trim out any offset in the system. However, proper Span calibration requires a pressure standard three to five times more accurate than the accuracy of the transducer, and there may also be interaction of Span on Zero. For detailed instruction see chapter 8.2.1.

CONNECTING AND DISCONNECTING CABLES, OR INSTALLING BOARDS INTO A SYSTEM WITH THE COMPUTER OR FIELD POWER ON MAY CAUSE DAMAGE TO THE I/O BOARD AND WILL VOID ALL WARRANTIES, IMPLIED OR EXPRESSED.TABLE OF CONTENTSChapter 1: Introduction (4)Figure 1-1: Block Diagram (6)Figure 1-2: Example of one Input Circuit (6)Chapter 2: Installation (7)Chapter 3: Option Selection (8)Figure 3-1: Option Selection Map (9)Chapter 4: USB Address Information (11)Chapter 5: Programming (12)Chapter 6: Connector Pin Assignments (13)Chapter 7: Specifications (15)Chapter 1: IntroductionThis board is an ideal solution for adding portable, easy-to-install digital I/O to any computer with a USB port. As a USB 2.0 high speed device it offers the fastest speed available with the USB bus, while being compatible with both USB 1.1 and USB 2.0 ports. The board is plug-and-play allowing for quick connect/disconnect whenever you need additional I/O on your computer.Model Options16 isolated digital inputs and 16 relay outputs, enclosure, module and screw terminal board16 isolated digital inputs only version16 relay outputs only version8 isolated digital inputs and 8 relay outputs versionAccessories:Internal plug in screw termination board (Green screw terminals = AWG 26-16)(Gray screw terminals = AWG 28-20)External power supply AC/DC adapterOptions:-OEM Board Only version (no enclosure or screw terminal board)-E Economy model (no screw terminal board)-DIN DIN rail mounting provisionFunctional DescriptionFEATURES:•High-Speed USB 2.0 device, USB 1.1 compatible•16 optically isolated inputs•16 Form C electromechanical 1A relays•Internal, removable screw terminal board for easy wiring•Small (4" x 4"x 1.25") rugged industrial enclosure•Custom high-speed function driver•PC/104 module size and mounting compatibilityINPUTSThe board provides sixteen optically-isolated inputs. These inputs can accept either AC or DC signals and are not polarity sensitive. Input signals are rectified by photocoupler diodes while unused power gets dissipated through a 1.8k-ohm resistor in series. The inputs may be driven by either DC sources of 3 to 31 volts (rms) or AC sources at frequencies of 40 Hz to 10 KHz. Standard 12/24 AC control transformer outputs can be accepted as well. External resistors connected in series may be used to extend the input voltage range, however this will raise the input threshold range. Consult with factory for available modified input ranges.Each input circuit contains a switchable filter that has a 4.7 millisecond time constant. (Without filtering, the response is less then 40 microseconds) The filter must be selected for AC inputs in order to eliminate the on/off response to AC. The filter is also valuable for use with slow DC input signals in a noisy environment. The filter may be switched out for DC inputs in order to obtain faster response. Filters are individually selected by jumpers. The filters are switched into the circuit when the jumpers are installed in position FLT0 to FLT15.OUTPUTSThe board’s outputs are comprised of sixteen FORM C SPDT electro mechanical relays. These relays are all de-energized at power-on.SCREW TERMINAL ACCESSORY BOARDA Screw Terminal Accessory board is included with the unit, except for the Economy (E) and OEM versions. The board provides access to all 80 I/O signals via removable screw terminals. Each removable screw terminal carries 8 I/O signals, signal names are clearly marked on the accessory board's silk screen. The screw terminal board plugs directly onto the I/O board while fitting inside the rugged industrial enclosure.USB CONNECTORThe USB connector is a Type B connector and mates with the cable provided. The USB port provides communication signals along with +5 VDC power. The board can be powered from the USB port or, if needed for higher current applications, an external power supply can be used.LEDThe LED on the front of the enclosure is used to indicate power and data transmissions. When the LED is in an illuminated steady green state, this signifies that the board is successfully connected to the computer and has been detected and configured by the operating system. When the LED flashes continuously, this signifies that there is data being transmitted over the USB bus.Figure 1-1: Block DiagramVcc.1uF4.7K1.8KFILTER JUMPER47KAC or DC INPUTFigure 1-2: Example of one Input CircuitChapter 2: InstallationSoftware CD InstallationThese paragraphs are intended to detail the software installation steps as well as describe what is being installed.The software provided with this board is contained on one CD and must be installed onto your hard disk prior to use.To do this, perform the following steps as appropriate for your operating system.

Please refer to the USB I/O Quick Start Guide which can be found on the CD, for specific, quick steps to complete the hardware and software installation.Chapter 3: Option SelectionRefer to the setup programs on the CD provided with the board. Also, refer to the Block Diagram and the Option Selection Map when reading this section of the manual.Input PowerThis is an option for applications that use more current than what your computer can provide on the USB port (typically 500 mA). The DC jack has a 2.00mm post on board and is designed to be used with the 9 VDC AC/DC external power supply that ships with this option. The voltage regulator on board regulates the 9 VDC and provides 5 VDC to the onboard circuitry. When using external power, switch the jumper located near the USB connector to VEXT, otherwise when the jumper is in the VUSB position current is drawn from the USB port.Filter Response SwitchJumpers are used to select input filtering on a channel-by-channel basis. When jumper FLT0 is installed, additional filtering is introduced for input bit 0, FLT1 for bit 1, etc.JUMPER SELECTION Bit Filtered JUMPER SELECTION Bit FilteredFLT-0 FLT-1 FLT-2 FLT-3 FLT-4 FLT-5 FLT-6 FLT-7 IN00IN01IN02IN03IN04IN05IN06IN07FLT-8FLT-9FLT-10FLT-11FLT-12FLT-13FLT-14FLT-15IN08IN09IN10IN11IN12IN13IN14IN15This additional filtering provides a slower response for DC signals as described previously and must be used when AC inputs are applied..Figure 3-1: Option Selection MapChapter 4: USB Address InformationUse the provided driver to access the USB board.

This is a safety issue so a careful approach is required. For CE certification, isolation was specified at 40V AC and 60V DC. The design intention was to eliminate the influence of common mode. Use proper wiring techniques to minimize voltage between channels and to ground. For example, when working with AC voltages do not connect the hot side of the line to an input. Tolerance of higher isolation voltage can be obtained on request by applying a conformal coating to the board.Customer CommentsIf you experience any problems with this manual or just want to give us some feedback, please email us at: *****************.Please detail any errors you find and include your mailing address so that we can send you any manual updates.Embedded SolutionsADL Embedded Solutions Inc., 4411 Morena Blvd., Suite 101, San Diego, CA 92117-4345P. +1 858 490-0597 F. +1 858 490-0599e-mail: *****************; web: 。

application 对象
问题：购物车能用 application 实现吗？
很明显，购物车是不能用 application 实现的。因 为不同客户在服务器端访问的是同一个对象，如果 使用 application 实现购物车，客户 1 向购物车中 放了一种物品，客户 2 也可以看到，那样是不允 许的
application 对象
application 对象的 API 主要有以下几个：
✓ 将内容放入 application
void application.setAttribute(String name,Object obj);
利用 session 保存登录信息
例子
假如用户登录学生管理系统，登录后用户可能要 做很多操作，访问很多页面，在访问这些页面的过 程中，各个页面如何知道用户的账号呢？
答案很简单，在登录成功后，用户的账号可以 保存在 session 中。后面的各个页面都可以访问 session 内的内容
application 对象
实际项目中，可以使session中的内容多种多 样。为了将session里面的内容很好地分门别 类，可以将这几种物品先放在一个集合中， 然后将集合放入session中，操作更加方便。
session 其他 API -session sion 有一个函数： void session.removeAttribute(String name);
如何用 session 开发购物车
一些 session 常用的 API
✓ 读取购物车中的内容
Object session.getAttribute(String name);
✓ 在该函数里面，name就是被取出的内容所对应的 标记；返回值，就是内容本身。

IS6940 CCloud Voice, Enterprise Mobility and Big Data Application in Real Estate AgencyAbstract & LearningsThis paper summarizes and analyses the talk about Cloud Voice, Enterprise Mobility and Big Data Application in Real Estate Agency by Francis Fung. He gave interesting insights into the real estate market and introduced three projects at Midland Realty [Midland]. He highlighted the importance that benefits should outweigh the costs of IT projects.This paper will therefore analyse the costs and benefits of the projects described by Mr Fung. It will be shown that there are additional costs for risks, which should be considered when using the IP Phone technology. For Enterprise Mobility and big data, alternatives will be discussed to the solutions implemented by Midland. It will be shown, that Midland could have achieved similar or even better benefits at a lower cost, following a different IT strategy.1. Seminar ContentIn this chapter the main points of the talk by Mr Francis Fung are summarized. As the title of the talk says, Mr Fung addressed a broad range of topics in his talk. He also gave insights into the company Midland, where he has been working as CTO for 9 years. Midland employs about 9000 people, mostly sales agents and has 300 branches in Hong Kong, where they share over 50% of the market with the main competitor. The challenge of connecting all branches in Hong Kong is solved by using cloud computing. Another challenge of the real estate industry is the large number of mobile sales agents, which bring their own devices and the high interaction with customers through various channels.Mr Fung talked about three projects of Midland- IP Phone, Enterprise mobility and Big Data, which show how Midland targets the challenges of the real estate market. He pointed out that before launching an IT project it is important to analyse the costs and benefits beforehand.IP PhoneMidland invested 1 Million dollars to set up an IP Phone infrastructure. They achieved cost savings because the different branches did not need single telephone connections anymore. Additionally voice recording was introduced to record all conversations, which also serves to monitor the sales agents e.g. by using the length of a telephone call as KPI for them. A benefit is the click to dial technology which avoids the exposure of client telephone numbers to sales agents and saves time. Enterprise MobilityEnterprise mobility. In the real estate market it is essential for sales agents to communicate with the customers. At Midland Reality in house developed apps exist to communicate with all employees. For instance there is a WhatsApp like chat service, so that the employees can communicate with each other. Mr Fung mentioned that the introduction of Enterprise mobility saved costs for SMS and reduced junk email. On the other hand there were more requests for technical support regarding the mobile apps by the employees.Big Data AnalysisAccording to Mr Fung, Midland uses big data to predict future sales and find target customers. He said that data is collected from social media (e.g. married, children, job etc.) and the website (clicks on certain objects) and is then merged to conduct some analysis using the data. Also data about houses and mortgage rates is collected to determine how much money somebody has. Mr Fung mentioned that using big data, Midland Reality found that people use more mobile devices to access the website during the weekend and more computers during the week.The goal of the big data project is to predict the right selling approach and find marketing campaigns based on customer demographics and customer behaviour. But Mr Fung admits that Midland does not have the capabilities yet to conduct the right analysis of the collected data.2. Discussion & AnalysisMr Fung gave interesting insights about recent IT projects and technologies used at Midland. In this section Ip Phone, Enterprise Mobility and big data is discussed and further aspects regarding these technologies will be covered. Additionally possible alternatives are introduced which might be better suitable for Midland.When talking about the IP Phone Mr Fung forgot to mention, that this technology also brings risks. As Hensell (2010) mentioned, there are security issues in using IP Phones. Using a method called phone phreaking, an attacker can gain access to the phone system using the remote access feature. Then the attacker can call anywhere in the world and the victim has to pay the bill. Even worse is, as Mark Lobel, a senior manager at Price Waterhouse Coopers warned, that "this is the first time that a computer virus can stop your telephones from working". There are a lot of security issues in VoIP networks which hackers can exploit to launch DOS attacks, record conversations or harvest customer data (Taub, 2008). The costs associated with those risks should be considered in analysing the profitability of the IP Phone project.I think an important factor for the IP Phone project was the surveillance of employees and the mistrust in them. It seems that Midland has not the best relation with its employees. As Mr Fung mentioned they have a fluctuation rate of 300 employees per month (respectively 3600 per year) which means that more than one third of the company fluctuates on a yearly basis. Therefore the IP Phone technology is used to hide client’s information to the sales agents. Blum et al. (2000) found, that use of surveillance and restricted control leads to less employee satisfaction. Therefore I think practices such as the recording of every conversation with customers and using the length as KPI puts a lot of pressure on sales agents and is one of the reasons for the high fluctuation rate. Enterprise MobilityMr. Fung mentioned in his talk that Midland develops Apps in house for internal and external use. I think some external apps are very useful but for the internal ones the money could be better spent.E.g. the property Information App, which uses augmented reality to display real estate information, can be very useful for customers because it can help to simplify their search for an appropriate apartment in Hong Kong. A benefit is that it puts Midland ahead of their competition which does not offer such apps. Unfortunately the app is only available in Chinese which makes it unusable for those who do not understand Chinese but those account to the minority of 4% of the population in Hong Kong which does not speak Cantonese (Census and Statistics Department, 2011).In my opinion implementing a real estate ERP System is a better alternative to the development of internal apps. Providers such as Ramco, Ignify, JBerp and many more1 provide solutions which cover all the requirements of a real estate company2 and are also available as cloud services3. According to Deacom (2014) & Winters (2011) it is cheaper to maintain a single ERP system than multiple software systems and they increase productivity because processes are optimized. Additionally an ERP System can be extended with other modules (, 2014) e.g. for big data analytics (see chapter Big Data). Midland could implement a cloud based ERP system such as ECOUNT and use SaaS for analytics4or use SAP and it’s powerful in memory database (HANA) to analyse big data5. Midland could have saved costs, by using an ERP system instead of developing all the apps in house. Especially for basic functionalities, such as a chat service or a calendar, the costs for developing these apps could have been saved by using freeware solutions or modules for ERP systems.1 https:///webhp?sourceid=chrome-instant&ion=1&espv=2&ie=UTF-8#q=real%20estate%20erp%20systems2 /industries/infrastructure/real-estate/3 /erp-software-real-estate.php4 /product/web-based/product-saas-erp-overview.jsp5 /solution/big-data/software/applications.htmlAccording to Connolly (2015) big data has potential in the real estate market in the following areas: ∙Determining the right price of a property∙Predicting when sellers want to sell∙Providing a transparent price overview for buyersO’Brian (2015) mentioned that a company called Zillow uses big data to fulfil the last point by providing complete transparency of real-estate info (see Screenshot below).Figure 1: Screenshot of Zillow’s websiteComparing Zillow with the website of Midland in Hong Kong some major differences can be identified:∙Midland has no interactive map which shows where the real estates are located∙The pictures don’t provide much information about the apartments∙Zillow efficiently combines a map and a table on one pageFigure 2: Screenshot of Midland’s websiteMidland also has a map feature on its website but unfortunately the properties are not included and no prices are displayed. The main purpose is to find different areas in Hong Kong (see Figure below).Figure 3: Screenshot of Mid land’s MapA lot of people commented in Connolly’s article (2015) that instead of big data, good data analysis tools, such as SAS, could also be used to fulfil the same purpose. I think that the claimed findings which Midland made using “b ig data”(the website had only an estimated 265,800 page views6 respectively 39,720 visitors7 in the last month) could be achieved using data analysis. For instance the finding, that people use mobile devices to access the website during the weekend could easily be visualized using Google Analytics, as shown on the figure below.Figure 4: Screenshot of Google Analytics86 /report/7 /report/8 /blog/wp-content/uploads/2014/08/GoogleAnalyticsMobile2.pngAdditionally Google Analytics provides a big variety of other analytics such as the Pages/Visit, Avg. Time on site and many more (See Screenshot below).Figure 5: Screenshot of Google Analytics9Mr Fung also mentioned, that Midland plans to use the recordings of the CCTV cameras at Midland branches to match faces of customers with their Facebook profile pictures. First of all I would like to mention, that I consider it as unethical to collect information of customers entering their branches, without them knowing it. Secondly it is not legal to conduct this kind of data matching, as Mr Fung confirmed. To identify new and returning customers, Google Analytics could be used for their website. Instead of building a marketing campaign using big data and collecting customers information via Facebook, Midland should try to improve it’s on Facebook page (only 928 likes), which can be also used as a good marketing tool (Folgate, 2014).Although it is not clear how much Midland spent on the big data project, it seems that the benefits of these projects have not been achieved yet. Even Mr Fung admitted at the end of his talk, that Midland has not found the right way yet to analyse the data. It was shown that cost could be saved using cheaper tools, such as Google Analytics for data analysis and Facebook for marketing.3. ConclusionMr Fung gave us interesting insights in three particular projects at Midland. This paper showed that the IP Phone is also used to control the employees more and to protect the customer information from them. This was identified as a reason for the high fluctuation rate at Midland because it reduces employee satisfaction. Additionally it was shown that an ERP system for real estate companies would be cheaper alternative to the costly development of in-house apps with additional benefits, such as the possibility of adding a big data analytics module.9/extensions/view/46/google-analyticsBy comparing Midlands’s website with Zillow, it was shown that Midland Realty should rather invest its money in redesigning the website. In my opinion Midland is not on the right track yet with their big data project. In terms of data collection they are building a good basis by collecting a lot of data from different sources, but Midland has not found the right way yet to analyse the data. I think Midland could also use a good data analytics tool such as Google Analytics for most of their purposes or do it right from by using the industry leader’s expertise and implement an ERP system with a big data module.ReferencesBlum, T. et. al, (2000), ‘Matching Creativity Requirements and the Work Environment: Effects on Satisfaction and Intentions to Leave,’Academy of Management Journal, 43(2), 215-224.Census and Statistics Department, (2011). 2011 Population Census – Summary Results.
