基于DataSnap和ActiveXForm技术的Web数据访问

通过Internet访问网络数据库是目前重要的一种Web应用模式。在Delphi中利用DataSnap和ActivexForm技术可以较好地实现以Web形式访问网络数据库。通过DataSnap技术可以使多层体系结构分布在Internet／Intranet上，而利用ActivexForm技术则可以将多层分布式数据库应用程序以浏览器来呈现，省去了客户端应用程序的安装和维护。本文介绍了在Delphi DataSnap和ActiveXForm的数据访问模式，分析了利用DataSnap和ActivexForm技术的结合实现对网络数据库的Web访问的方法，并给出了一个具体的设计步骤。

Web Data Access Based on DataSnap and ActiveXForm Technique

It is a kind of important Web application mode at present to access network database through the Internet. Making use of the DataSnap in Delphi with ActiveXForm technique, it can be realized to access the network database with Web form well. The multi-layer system construction can be distributed on the Internet/Intranet passing through the DataSnap technique, and the multi-layer distributed database application program can be presented with browser by using ActiveXForm technique, it leaves out the installation and maintenance of client application program. This article introduces the DataSnap and ActiveXForm data access pattern in Delphi. The network database Web access has been analyzed and realized, by the method of DataSnap and the ActiveXForm combination technology. A concrete design procedure has been produced.
