Research, Content-based Multimedia Database Engine And Its Architecture

With great development of multimedia technology in recent years, multimedia data becomes a very important part of user's information resources. Compared with the traditional relational database management system, which supports simple data type, multimedia database has the characters of close information relationship, complex data type, great capacity of data amount, highly efficiently processing ability, etc. What's more, in application, users hope database management system can not only manage data efficiently, such as storing, indexing of great capacity, but also have the ability to process multimedia content automatic or semi-automatic, such as structurizing analysis, content analysis, syntax analysis, abstract generating, etc, to help users to capture the related information quickly. So how to develop the existing database management system, to make it restore more multimedia information on the base of inheriting the existing functions, and to support database management system for users to develop multimedia application have been in instant need in the era of information.In this thesis, after studied mans kinds of multimedia database management systems, and take the practice demands into consider, we propose a new method of "content-based multimedia database engine + object-relational database management system" to construct content-based multimedia database management system. Through experiments testifying, it is proved that the method we proposed can be competent for the management task of the content-based multimedia database.The main work of this thesis consists:1. Bring forward the architecture of content-based multimedia database engine. Studied the combination methods of content-based multimedia database engine and database management system, and the various supporting-technology for content-based multimedia database engine in object-relational database management system, such as data type extending, inheriting, rule, big object.2. Studied the key module of content-based multimedia database engine. DataTool module, then design and complete DataTool module on the base of Oracle database.3. Design and implement content-based multimedia database engine. And through experiments, it is proved that the method we proposed can be competent for the management task of the content-based multimedia database.
