Multimedia Data Based On Object Technology Support Environment

In this paper, I will describe the main characteristics of e-Support , the Multimedia Data Support Environment Based on Object-Oriented Theory. In the trend of broadening the scope of Database , more and more users find that the traditional Relational Database cannot meet the needs of multimedia data . So we develop the software, e-Support , to meet the needs mentioned above.e-Support is a database management system based on the theory of Object Oriented. It contains the architecture of Client!Server and Browser! Server. Most of the characteristics of Object Oriented are embodied in the system , such as the Data Model of 00 , Expression of Object , Mechanism oflnherit, OlD , Object Reference, Object Transmission, etc . To the best of out ability , We apply the theory of 00 into the design of e-Support.For the reason of high Performance and Scaleness , we use SQL Server as the back-end database . So it deals with the projection from Data Model to Data Pattern. One strongpoint of e-Support is that it support the most common multimedia data type, such as Image , Video , Sound , RTF Text . User can manipulate the multimedia data freely in the environment of e-Support . We will describe how to solve the problem of processing the multimedia in this paper detailedly.The Structure Query Language(SQL) can query out the records we need, and it is well accepted in database application . But we know that the resultset of SQL is expressed in two-dimension table , so it can be used in expressing the nonstructure data, such as multimedia data . We develop the Object Query Language (OQL) based on SQL . It is compatible with SQL, and has its own grammar. The resolution of OQL is described in chapter 7.We apply the Component Object Model in the design of three tiers Application Architecture, and it support the object transmission within the environment of network. In Chapter 8 and 9 we will give the description of these two parts in detail.The Enterprise Data Support Environment Based on Multimedia, e-Support, is the expansion of tradition relational database management system , It is based on the theory of Object Oriented, and supports Multimedia Data .We can apply it in many fields of computer science, such as Multimedia Database , Office Automation , Data Transmission, etc . It has a vast range of prospects.
