Exercises 1-answer

Exercises 11.List significant differrences between a file-processing system and a DBMS.2.What are the advantages and disadvantages of database?3.Explain the difference between physical and logical data independence.Discuss the ANSI-SPARC three-level architecture.4. What is a data model? Discuss the main types of data models.An integrated collection of concepts for describing and manipulating data, relationships between data, and constraints on the data in an organization. (See Section 2.3.)Object-based data models such as the Entity–Relationship model (see Section 2.3.1). Record-based data models such as the relational data model, network data model, and hierarchical data model (see Section 2.3.2). Physical data models describe how data is stored in the computer (see Section 2.3.3).Answer:•Physical data independence is the ability to modify the physical scheme without making itnecessary to rewrite application programs. Such modifications include changing from unblocked to blocked record storage, or from sequential to random access files.•Logical data independence is the ability to modify the conceptual scheme without making itnecessary to rewrite application programs. Such a modification might be adding a field to a record; an application pr ogram’s view hides this change from the program.Exercises 21.The following tables form part of a database held in a relational DBMS:Hotel (hotelNo, hotelName, city)Room (roomNo, hotelNo, type, price)Booking (hotelNo, guestNo, dateFrom, dateTo, roomNo)Guest (guestNo, guestName, guestAddress)where Hotel contains hotel details and hotelNo is the primary key;Room contains room details for each hotel and (roomNo, hotelNo) forms the primary key;Booking contains details of the bookings and (hotelNo, guestNo, dateFrom) forms the primary key;and Guest contains guest details and guestNo is the primary key.Identify the foreign keys in this schema. Explain how the entity and referential integrity rules apply to these relations.For each relation, the primary key must not contain any nulls.Room is related to Hotel through the attribute hotelNo. Therefore, the hotelNo in Room is FK，and should either be null or contain the number of an existing hotel in the Hotel relation. In this case study, it would probably be unacceptable to have a hotelNo in Room with a null value.Booking is related to Hotel through the attribute hotelNo. Therefore, the hotelNo in Booking is FK，and should either be null or contain the number of an existing hotel in the Hotel relation. However, because hotelNo is also part of the primary key, a null value for this attribute would be unacceptable.Similarly for guestNo. Booking is also related to Room through the attribute roomNo,(guestNo,roomNo) in booking is FK reference Room. guestNo in booking is FK reference Guest.Describe the relations that would be produced by the following relational algebra operations:(a)∏hotelNo (σprice> 50 (Room) )This will produce a relation with a single attribute (hotelNo) giving the number of those hotelswith a room price greater than £50.(b)σHotel.hotelNo=Room.hotelNo(Hotel⨯Room)This will produce a join of the Hotel and Room relations containing all the attributes of bothHotel and Room (there will be two copies of the hotelNo attribute). Essentially this willproduce a relation containing all rooms at all hotels.Produce some sample tables for these relations that observe the relational integrity rules. Suggest some enterprise constraints that would be appropriate for this schema.Student should provide some sample tables, observing entity and referential integrity. In particular, ensure the uniqueness for the composite primary keys of the Room and Booking tables.Some enterprise constraints may be:•There can be no two bookings for the same room in the same hotel on the same day.•For the Booking relation, dateFrom must be before dateTo.•Room price must be greater than 0 and less than £200.3.Consider the relational database of Figure 1,employee (person-name, street, city)works (person-name, company-name, salary)company (company-name, city)manages (person-name, manager-name)Figure 1. Relational databasewhere the primary keys are underlined.Give an expression in the relational algebra to express each of the following queries:a.Find the names of all employees who work for First Bank Corporation.b. Find the names, street address, and cities of residence of all employees whowork for First Bank Corporation and earn more than $10,000 per annum.c. Find the names of all employees in this database who live in the same cityas the company for which they work.Answer:a. Πperson-name (σcompany-name = “First Bank Corporation” (works))b. Πperson-name, street, city(σ(company-name = “First Bank Corporation” ∧salary > 10000)works ×employee)e. Πperson-name (employee ×works×company)。

They were talking loudly. I got very angry. I could not hear the actors. I turned round. I looked at the man and the woman angrily. They did not pay any attention. In the end, I could not bear it. I turned round again. 'I can't hear a word!' I said angrily. ‘It’s none of your business,' the young man said rude ly. 'This is a private conversation!'.上星期我去看戏。

UNIT 1PASSAGE APolar Differences Between Chinese and American CulturesAmericans wear black for mourning. Chinese wear white. Westerners think of dragons as monsters. Chinese honor them as representations of God. The polarities between Chinese civilization and the West often make it seem as though each stands at extreme ends of the earth. Now a University of California, Berkeley, psychologist has discovered deeper polarities between Chinese and American cultures-polarities that go to the heart of how we reason and discover truth.在丧礼上，美国人穿黑色丧服，而中国人穿白色。

西方人认为龙是怪物，而中国人把龙当成神明。

中国与西方的文明差异使它们看起来像分别站在地球的极端。

最近加利福尼亚的一所大学的心理学家伯克利发现中国和美国文化差异的更深极性，那是关于内心深处的如何理性和发现真理的极性。

His findings go far toward explaining many of the differences between Chinese and American cultures, when compared to each other. More importantly, the research opens the door for the peoples of the East and the West to learn from each other in basic ways. The Chinese would learn much from Western methods for determining scientific truth, said Kaiping Peng, a former Beijing scholar, who is now a UC Berkeley assistant professor of psychology, and Americans could profit from Chinese ways of accepting contradictions in social and personal life.他的研究结果对于解释许多中美文化对比的差异有很大的贡献。

It is as essential as the air we breathe, and just as intangible. It comes from the depths of our core, yet it is reflected in every single outward action we take, grand or small. It is the essence from which we measure our worth and the most important building block in the foundation of our intangible..8 Functioning like a magnet, Hollywood draws ambitious young people from all over the world.9 Acceptance or rejection of your body only carries weight in your mind; it has no bearings on how you actually look, so why not choose the ease of acceptance rather than the pain of rejection? The choice is yours.10 Behaviorists suggest that the child who is raised in an environment where there are many stimuli which develop his or her capacity for appropriate responses will experience greater intellectual development.11 Illegal immigrants are flooding into the United States, fuelling international disputes12 Many new industries which do not need to be close to their markets have been built up in the south and west, partly with the idea that well-qualified northern workers, alreadysatisfied by their high living standard, will think that better surroundings and warmer winters will make their living standards still higher.13 Many men have recognized the similarity of plants to the behavior of animals, and have dreamed wistfully, but forlornly, upon some method or source of rejuvenation such as Ponce de Leon sought in the Fountain of Youth several centuries ago.14 The automobile has brought many changes in American life---for example, the remarkable growth of the suburbs in the past 25 years as many people who work in the cities now enjoy country living because of good roads and the ease of commuting by automobile.

A recent survey revealed that the divorce rate has rocketed as women’s financial dependence on men has plummeted.34. The music industry is getting raided by the internet because it is so easy to make unauthorized copies of songs.35. The increase in DINK families has shattered the traditional idea of Chinese family.36. Just as all nations can benefit from the promise of this new world, no nation is immune to its perils.37. When I try to understand what it is that prevents so many Americans from being as happy as one might expect, it seems to me that there are two causes, of which one goes deeper than the other.38There is probably no better way for a foreigner (or an Englishman) to appreciate the richness and variety of English language than by studying the various ways in which Shakespeare used it.39At first, I was poor. Then I became needy. Later I was underprivileged. Now I’m disadvantaged. I still don’t have a cent to my name, but I sure have a great vocabulary.(* euphemistic words used by the government to mean ―poor‖—added by xiao mi)40No transport system in the world carries so many passengers by night or by day as the Greyhound buses which go almost anywhere in the United States.41To save embarrassment to people still living I have given to the persons who play a part in this story names of my own contriving, and I have in other ways taken pains to make sure that no one should recognize them.42Public officials may be removed from office for failing to perform their duties properly as well as for serious violations of law.43I had unforgivably, in a stealthy manner, peeped at her correspondence.44The conveniences that Americans desire reflect not so much a leisurely lifestyle as busy lifestyle in which even minutes of time is too valuable to be wasted.45The greatness of a people is no more determined by their number than the greatness of a man is determined by his height.46. Emphasizing the English language’s impact by its commercial activities across the globe, the United States has brought facets of its culture to almost every country.47. Since the last travel and work restriction were abolished in the European Union, the young have pursued their ambitions freely, helping to make Europe’s economy even more vibrant.48. In British it is necessary to prepare food rapidly in large quantities, and the taste of the food inevitably suffers, though its quality, from the point of view of nourishment, is quite satisfactory.49. E-mail has challenged the fax machine which was the preferred method of transmitting printed matter in the early 1990s.50. He was a clever man; a pleasant companion; a careless student; with a great propensity for running into debt, and a partiality for the tavern.51. It is not only in affluent societies that people are obsessed with the idea of making more money. Consumer goods are desirable everywhere and modern industry deliberately sets out to create new markets. Gone are the days when industrial goods were made to last forever. The wheels of industry must be kept turning. ―Built-in obsolescence‖ provides the means: goods are made to be discarded. Cars get thinner and thinner. You no sooner acquire this year’s model than you are thinking about its replacement.52. This materialistic outlook has seriously influenced education. Fewer and fewer young people these days acquire knowledge only for its own sake. Every course of studies mustlead somewhere: i.e. to a bigger wage pocket. The demand for skilled personnel far exceeds the supply and big companies compete with each other to recruit students before they have completed their studies. Tempting salaries and ―fringe benefits‖ are offered to the m. Recruiting tactics of this kind of have led to the ―brain drain‖, the process by which highly skilled people offer their services to the higher bidder. The wealthier nations deprive their poorer neighbors of their most able citizens. While Mammon is worshipped as never before, the rich get richer and the poor, poorer.53. The big cities must cope with inner-city poverty which spawns crime and drug abuse, and racism which arises from their multiracial populations.54. The agricultural revolution in the 19th century involved the invention of laborsaving machinery and the development of scientific agriculture.55. The economic differences between the North and the South and their different views of the relationship between the federal government and the states led to the Civil War in 1861.56. The best friend a man has in this world may turn against him and become his enemy. His son or daughter whom he has reared with loving care may prove ungrateful. Those who are nearest and dearest to us, those whom we trust with our happiness and our good name, may become traitors to their faith.57. Subjection of nature’s forces to man, machinery, application of chemistry to industry and agriculture, steam-navigation, railways, electric telegraphs, clearing of whole continents for cultivation, canalization of rivers, whole populations conjured out of the ground--- what earlier century had even a presentiment that such productive forces slumbered in the lap of social labour? (Manifesto of the Communist Party).58. Almost from the beginning of his term in office, President Clinton was dogged by rumors of his marital infidelity and financial corruption.59. The isolation of the rural world because of distance and the lack of transport facilities is compounded by the paucity of the information media.60. There is a mounting awareness on the part of the public of the gravity of corruption.61. Along with the realization that her superior was a venal official came understanding that the department under his thumb was not only oppressive but also rotten through and through.62. The thought that she would be separated from her husband during his long and dangerous journey saddened Mrs. Brown.63. Music whose meaning is slightly different with each hearing has a greater chance of remaining alive.64. American presidents tend to be judged less by the good deeds they set in motion than by how well they respond to crises.65. The line of demarcation between the adult and the child world is drawn in many ways. For instance, many American parents may be totally divorced from the church, or entertain grave doubt about the existence of God, but they send their children to Sunday school and help them, to pray. American parents struggle in a competitive world where sheer cunning and falsehood are often rewarded and respected, but they feed their children with nursery tales in which the morally good is pitted against the bad, and in the end the good inevitably is successful and the bad inevitably punished.66. Having children---especially the first child---puts a bigger strain on a couple’s relationship than anything else they ever do; some who stay together emerge stronger and richer, but a heck of a lot never recover.67. So a future of smaller families and more people choosing not to have children at all could well leave couple closer than they are today; for many, the purpose of being together would be solely to pleasure and support each other---an interesting prospect.68. Problems arise because too much water or too little water occurs at a certain place at a certain time, and these problems are increasing in number and magnitude each year.69. After all, eighty was a special birthday, another decade lived or endured just as you chose to look at it.70. One-room schools are part of the heritage of the United States, and the mention of them makes people feel a vague longing for ―the way things were.‖71. He always sits on the very edge of his chair when he is working, as though about to take off.72. The difference that distinguished them were obviously associated with the different social lives they had led.73. The main objection to vegetarianism on a long-term basis is the difficulty of getting enough protein, the body-building element in food.74. The combination of this Oriental city’s geography and the absence of import taxes has long made Hong Kong the ideal storehouse for transit goods to and from Asia.75. One attractive feature of the two-year college in the United States is that the faculty’s primary professional responsibility is to teach. At many four-year colleges and universities, research is, to put it mildly, at least as important as how an instructor performs in the classroom. The tension between research and teaching so common at comprehensive universities is not a factor at two-year institutions, where the good of the student is without doubt the instructor’s number-one concern.76 It is simple enough to say that since books have classes---fiction, biography, poetry---we should separate them and take from each what it is right that each should give us.77. Yet few people ask from books what books can give us. Most commonly we come to books with blurred and divided minds, asking of fiction that it shall be true, of poetry that it shall be false, of biography that it shall be flattering, of history that it shall enforce our own prejudices.78. If we could banish all such preconceptions when we read, that would be an admirable beginning. Do not dictate to your author: try to become him. Be his fellow-worker and accomplice.79. If you hang back, and reserve and criticize at first, you are preventing yourself from getting the fullest possible value from what you read. But if you open your mind as widely as possible, then signs and hints of almost imperceptible fineness, from the twist and turn of the first sentences, will bring you into the presence of a human being unlike any other.80. Steep yourself in this, acquaint yourself with this, and soon you will find that your author is giving you, or attempting to give you, something far more definite. The thirty –two chapters of a novel---if we consider how to read a novel first---are an attempt to make something as formed and controlled as a building: But words are more impalpable than bricks; reading is a longer and more complicated process than seeing.81. Locked up with my reading, I am completely alone. It’s just my book and me. What a delight! No one can read this text, on this page, in my place. Moreover, no one knowswhat I’m reading. It’s a purely selfish pleasure. In the morning, I’m happier and fresher. I feel renewed. Like an athlete, I’m better at some moments than at others. This morning I’m the best at reading.82. Throughout his life, Benjamin Franklin continued his education, learning from human contacts as well as from books.83. Books of voyages and travels became my passion, and in devouring their contents, I neglected the regular exercises of the school.84. What makes community colleges unique within the spectrum of American higher education is their policy of open enrollment.85. When you first glimpse Macau on the ferry form Hong Kong, it looks less than impressive. The skyline is dull compared to the imposing glass skyscrapers of Hong Kong, and most people do not take the time to revise this first impression, devoting on more than a day trip to it. But this does not do justice to this city of two cultures, which hides plenty of interesting secrets.86. We know more about the moon 240,000 miles away than we know about the three-fourth of the earth covered with water.87. As this century unfolds and people look back on this day, they will conclude that in admitting China to the WTO we took a decisive step in strengthening the global economic trading system.88. He was puzzled that I did not want what was obviously a ―step up‖ toward what all Americans are taught to want when they grow up: money and power.89. Insects would make it impossible for us to live in the world; they would devour all our crops and kill our flocks and herds, if it were not for the protection we get from insect-eating animals.90. And he knew how ashamed he would have been if she had known his mother and the kind of place in which he was born and the kind of people among whom he was born.91. If she did not speak with Rebecca on the tender subject, she compensated herself with long and intimate conversation with Mrs. Blenkinsop, the house keeper, who droppedsome hints to the lady’s maid, who may have cursorily mentioned the matter to the cook, who carries the news, I have no doubt, to all the tradesmen.92. A notion has taken hold in the United States to the effect that the only people who should be encouraged to bring children into the world are those who can afford them.93. I visited the neighboring villages, and added greatly to my stock of knowledge, by noting their habits and customs, and conversing with their sages and great men.94. From the standpoint of the developing countries, the next decade should see a greatly accelerated program for scientific and technological co-operation, aimed at wide-spread dissemination of technology for meeting the basic needs of man, such as nutrition, shelter, communications, health and sanitation.95. There is, of course, no single pattern of American characters any more than there is a single English or Turkish or Chinese character.96. There is much to be desired for the government to crack down bribery and corruption.97. Examinations test your knowledge and your ability to apply your knowledge, but not very much more. What is o often forgotten is that there are many valuable qualities which cannot be tested by examinations. Can you imagine, for instance, an examination in tact or good manners, in kindness or in honesty?98 Not only do Englishmen get several different sorts of weather in one day, but they may very well get a spell of winter in summer and vice versa.99. The 21st century executive must be a global strategist, working as deftly in Tokyo as in New York. He sees ---then seizes---markets worldwide.100. Someone once remarked that the British and the Americans are two peoples separated by the same language. Most epigrams exaggerate for effect, and this one is no exception. But it is, nevertheless, undeniably true that some commonly used words mean different things in these two cultures.Consider the seemingly single term-"the government." To parliamentarians trained in British terminology, "the government" means "the cabinet: a group of the legislature's own members, chosen by it to devise public policies, to manage the legislature's major activities, and to exercise executive powers.。
