In the course of development of online examination system, the B/S structure and the typical 3-layer model including data layer are adopted. The dissertation emphasizes on how to make use of storing process to realize data layer service through storage, base class in constructing the data service layer, and entry to the unified data operation based on .net platform. And it has further explained how to realize the storing of operation through base-class and utilize the advantages of storing for data layer service. All that could improve operational efficiency of program and enable base-class to work in operation of all DBbase in development of online examination system, which could be easily maintained, updated and reused maximally, and the data in base would be enlarged conveniently. It might be useful in the course of development of information system.
