The Research Of The Management Platform Based On The Database Multimedia Resource Base

This article first has made the brief outline based on the database multimedia management platform, then thoroughly discussed the research of the management platform based on the database multimedia resource base, elaborated with emphasis the resource base management platform' s the system structure, the system design, the implementation technology.The first part simply introduced the paper research background and the significance, including: the development present situation and the existence question of the management platform based on the database multimedia resource base, the characteristic of the management platform based on the database multimedia resource base, the characteristic and the research significance of the management platform based on the database multimedia resource base which the paper studied.This article second part make the thorough discussion of the management platform based on the database multimedia resource base, which the system structure mode. This platform uses three Browse/Server which the mature b/s structure system and the web database system (browser/server) the system structure, this kind of mode implemented the information from the static state to release to the dynamic release transformation, it had the client/server system the joint operation, reduces the network bandwidth, the simplification user operation interface, enhances system characteristic and so on openness, has overcome the c/s system structure flaw of the front system, caused the user to use the unified browser interface, the web development centralism in the server terminal development, as well as the system environment aspectimplements the cross platform, completely distributes. The long range data service is three clients/servers mode core, in three clients/servers mode long range data service has implemented to the user interface, the commercial logic rule, the digital data service logical separation and the independent seal, data buffer reduced the client end to request to the database service data, also caused the client end the application to stand then obtains the data but not to use the waiting network the data transmission.The advanced education thought and the idea are required in the system design, the system development uses the modular design, has the very strong expandability and the probability, also may use in WAN the wide range on-line teaching, also may according to all levels of each category of school need, carry on the modular combination, applies in the campus network. At the same time, in order to increase for the system resource service and the resource management, forms the constitutive modulation the overall design plan, according to the resource type partition, divides into the resource the media source material, the test question, the network class, the case, the literature information and so on many administration module, and module conformity, processing. Because uses this kind of modular design, regardless of is the case, the source material or the class, although the resource base management system management system each module specific data shape and the attribute are not so whole like, but the basic function and the implementation are similar, conveniently to program development. Carried us in the client to select the method which the information graduation presented, namely the user first selected the information type which had to browse (for example network class, media source material), then readout subclass (for example video frequency, animation and so on). Said to the browser, in server end shield source code, background processing data, implementation function and so onresource downloading, use track, retrieval resource, single bond inquiry. This is the article third part.This article fourth part is to the platform system technical implementation research. This part first introduced the multimedia database implementation principle and the technology, then introduced controls the platform the implementation technology, the key elaboration middleware...
