UniWeb2.0:Web与数据库间的网关实现

大规模数据库服务系统可以通过集成Web服务器的服务功能和数据库系统的数据管理功能来实现，集成的关键部分是数据库网关。本文首先介绍了CGI应用服务器数据库网关结构，然后介绍了数据库网关Uniweb2．0的设计和实现。U－niWeb2．0集成了Web和对象-关系数据库管理系统UniSQL／X，它采用CGI应用服务器结构来实现高性能并可用于交叉平台。UniWeb2．0也允许程序员将包括SQL／X状态的Tcl描述嵌入到HTML文件中。

Large scale database service system can be implemeted by intergrating service capability of the Web and the data management facility of database systems in complimentary fashion. A database gateway is the core component in suchintergration.In this paper, we first introduce the CGI application sever database gatewayruntime architecture. We then introduce the detailes of the design and implementation of niWeb 2. 0. UniWeb 2. 0 intergrates the UniSQL/X object - relationaldatabase management system and the Web, it adopted the CGI application serverarchitecture to achieve higher performance and cross - platform availablity. UniWeb 2. 0 also allows programmers to embed Tcl scripts containing SQL/X statements into HTML documents.
