多媒体数据库翻译

Multimedia Database

Multimedia data typically means digital images, audio, video, animation and graphics together with text data. The acquisition, generation, storage and processing of multimedia data in computers and transmission over networks have grown tremendously in the recent past.

多媒体数据是指由数字图象、音频、视频、动画制作等一起组成的文本数据。近来，多媒体数据在计算机中的获得、产生、存储、执行的速度以及在网络中的传输速度已经有了极大地提高。

This astonishing growth is made possible by three factors. Firstly, personal computers usage becomes widespread and their computational power gets increased. Also technological advancements resulted in high-resolution devices, which can capture and display multimedia data (digital cameras, scanners, monitors, and printers). Also there came high-density storage devices. Secondly high-speed data communication networks are available nowadays. The Web has wildly proliferated and software for manipulating multimedia data is now available. Lastly, some specific applications (existing) and future applications need to live with multimedia data. This trend is expected to go up in the days to come.

这种令人吃惊的增长速度可能是由三个因素造成的。首先是，个人计算机功能的不断强大和普及，技术的发展产生了能够获取和播放多媒体数据的高技术和大容量的存储设备。其次是，目前在网络中已经能进行高速的数据传输，在广泛的互联网中运用软件来操作处理多媒体数据已经成为了可能。最后是，未来一些特殊的需求是要依靠多媒体数据的，这种趋势是未来所期待的。

Multimedia data are blessed with a number of exciting features. They can provide more effective dissemination of information in science, engineering ,

medicine, modern biology, and social sciences. It also facilitates the development of new paradigms in distance learning, and interactive personal and group entertainment.

多媒体数据有许多令人振奋的特点。它能在科学、工程、医学、现代生物学和社会科学中提供更有效的信息传播。它也使得网上学习中的新范例的发展和个人与团体娱乐设施的相互影响得变便利了。

The huge amount of data in different multimedia-related applications warranted to have databases as databases provide consistency, concurrency, integrity, security and availability of data. From an user perspective, databases provide functionalities for the easy manipulation, query and retrieval of highly relevant information from huge collections of stored data.

各种与多媒体相关的大量数据都要求有能提供数据的一致性、同时性、完整性、安全性和存在性的数据库。从用户的角度来看，数据库为从存储的数据中收集有紧密关联的信息提供了简单的操纵、查询和检索功能。

MultiMedia Databases (MMDBs) have to cope up with the increased usage of a large volume of multimedia data being used in various software applications. The applications include digital libraries, manufacturing and retailing, art and entertainment, journalism and so on. Some inherent qualities of multimedia data have both direct and indirect influence on the design and development of a multimedia database. MMDBs are supposed to provide almost all the functionalities, a traditional database provides. Apart from those, a MMDB has to provide some new and enhanced functionalities and features. MMDBs are required to provide unified frameworks for storing, processing, retrieving, transmitting and presenting a variety of media data types in a wide variety of formats. At the same time, they must adhere to numerical constraints that are normally not found in traditional databases.

多媒体数据库必须处理运用在各种应用软件中不断增加的大量的多媒体数据。这些应用包括数字图书馆、制
