Software Database Design. The design of software database has been completed, and 4 main table structures and the model of corresponding field for database tables have been finished as well.

Index Structure Design of Search Engine. As the core of the searching function of this program, index structure has been designed, and the synchronization mechanism with database has been completed, through which any change in the database will be synchronized into the index data of search engine spontaneously.

Prototype Design of Program Functions. The program includes video searching and playing, uploading, editing, deleting and other managerial functions of relevant videos. As for the video playing function, it is realized mainly in the form of website player. Selective video playing on website page has come true, and users can start, pause or fast forward during the process. The searching function makes use of Chinese lexical analysis algorithm with open source program Lucene at the core and it has been realized by searching in Chinese for videos which complete early artificial process and marking. The overall frame of managerial functions has been completed and the users can enter the backstage to add, delete, search, and edit the existed video library after identity verification.

Video library is in the process of software developing and coding. At present, 21 Java files of source code have been finished including 3,370 lines of codes and 12 configuration files. The size of Java codes reaches 107 KB.
