Abstract :
With the development of computer technology and network communication technology and multimedia technology, database technology has become an important technical means and software technology for organizing and managing large amount of data in information society. It is the foundation of network information management system. It not only has a complete theoretical basis, and with the rapid development of hardware technology and software technology, its application is more and more widely. However, the rapid development of information technology is that people face such a situation: CAD / CAM, CIMS, CASE, GIS and other applications require the management of increasingly complex information, such as multimedia data, such as multimedia data, spatial data, scientific data, Data and other data types, these data compared with the traditional type, not only the type of complex, diverse forms, and storage, transmission, operation and retrieval methods also have many new features, new requirements, on the one hand, the need for database technology and database systems To manage these complex data in order to obtain the database system has many of the data management functions, such as query, retrieval, recovery, concurrency control, integrity, storage management. On the other hand, due to the vigorous development of network technology, information processing has long been from a single user environment to the development of the network environment,
this environment for resources, information sharing provides a great convenience, and because of multi-machine work together to greatly improve the work , The combination of the two requires that the database management system be able to manage complex data objects in a networked environment or heterogeneous environment. Traditional DBMSs cannot eff ectively handle complex multimedia data, thus requiring the use of new multimedia indexing and retrieval techniques. Multimedia database technology is an important part of computer technology, it can simultaneously acquire, process, edit, store and display text, sound, video, graphics and other diff erent media, while it has diversity, integration and interactivity and so on. Only to solve the key technical issues of multimedia, can be widely used to promote its faster development.
