Based on MVC ( Client Middleware Server) concept and VisualDB technology, we designed and implemented the Service System of the South China Sea Science Data Products (SCSPD). Users can query, search and access data products in the SCSPD visually via Web browser. In this paper, the application of VisualDB was introduced. Software architecture design of the system , visualized process of data management and release were described in detail. In the last section , we discussed the system expansibility of the SCSPD according to the technical characteristics and application of VisualDB. The SCSPD improves data service forms of the South China Sea Ocean Database, and is instrumental in the construction of the South China Sea Data Sharing and Service System.
