开放安全的Internet/Intranet信息系统体系结构的研究与实现

由于ＷＷＷ技术的迅猛发展与普及，特别是其开放的体系结构，使得它成为当今计算机应用的理想平台。如今，许多应用，尤其是商业领域的应用，已经在ＷＷＷ上成功地建立起来。但是传统的客户／服务器数据库管理系统与ＷＷＷ互连还存在许多问题，特别是在一些全新的商业应用提出后，这种问题愈显突出。正是在这种背景下，笔者研究了目前 Ｃｌｉｅｎｔ／Ｓｅｒｖｅｒ ＤＢＭＳ与 ＷＷＷ互连中存在的困难和障碍，分析了问题的实质，并提出全新的开放安全 Ｉｎ－ｔｅｒｎｅｔ／Ｉｎｔｒａｎｅｔ信息系统体系结构，对该体系结构的各组成部分进行了详细的定义和研究。在理论研究的基础上，及Ｉｎｔｒａｎｅｔ环境中，设计并实现了一个简单的数据库信息实时发布系统，验证了所取得的部分理论成果，同时以该系统作为基础，还可进一步开发成为实用的商业软件系统。

Analysis and Implementation of an Open & Security Internet/Intranet Information System Architecture

As WWW is growing rapidly, it becomes a popular issue in computer world. Especially because of its open architecture, WWW is the best platform for establishing computer application system. Today, so many application systems, such as business systems, have been built on WWW environments successfully. The merging of Client/ Server database management system (DBMS) and Web information system can not he avoided. Many products for connection are available on foe market, but we have to encounter new problems, such as security, credit, perfor- mance and genericablity . We should resolve them quickly. Most of popular products are not the suitable solutions. In this circumstance, after analyzing and researching these problems deeply, we raise a new four-tire Open & Security Internel/Intranet Information System (OSIIS) architecture. We define the functions and process procedure of every tire in OSIIS. Besides academic research, we designe and implement a simple Database Information Real-time Publishing System (NK-DIRPS) on intranet. This simple system is able to transport data between web browsers and back-end database server dynamically. Not only the browser hut also the database server can send data to the other side on its own initiative. We believe that the new OSIIS architecture will propel the WWW and e-business development in the short future.
