基于DCOM的Web与数据库集成系统的体系结构

The Architecture of Integration of Web and Database System Based on DCOM

1 引言随着网络技术的发展,Web日趋成为目前重要的信息系统。数据库系统如何与Web集成(DBMS-Web)成为数据库研究领域的重要课题。这一集成可以充分发挥DBMS高效的数据存储和管理能力,以Web为平台,将客户端融入Web浏览器,为Internet用户提供简单方便、内容丰富的服务。具体地,数据库系统与Web的集成具有以下优点:(1)客户端的平台独立性。客户端统一使用Web浏览器,从而省去了在Client/Server模式下为不同的平台开发客户程序的重复劳动。(2)系统的可伸缩性,易于扩充和修改。(3)对于用户来说,界面统一,易于使用。

The integration of Web and database system has become the important issue in the field of database research with the development of network. In this paper, we present the implementation method of integration of Web and DBMS DM3 using Microsoft's DCOM. Utilizing the idea of component, we solve some problems of the integration,such as the performance of the whole system when the number of client increases, how to maintain the ACID characteristic of the transaction in the environment of the HTTP protocol,and so on.
