Building Three-Tier Client/Server Applications with Visual FoxPro
Robert Green
Microsoft Corporation
January 1997
Introduction
Your good friends on the Visual FoxPro™ team at Microsoft spent a great deal of time to make Visual FoxPro a robust and powerful front-end for client/server applications. Remote views and SQL pass-through provide powerful tools to take advantage of SQL back-ends such as Oracle and SQL Server via ODBC (Open Database Connectivity).
One of the great truisms of application development is that there are many ways to do everything. One of the hardest things to do when building an application is to decide on an approach and to know if it is better than the other approaches. In client/server development this is compounded by the fact that you are dealing with two database engines, Visual FoxPro on the front-end and a very powerful SQL database e在客户-服务器三层结构中用Visual FoxPro创建应用
在微软公司Visual FoxPro 团队中的人员花了篅@さ氖奔涫筕isual FoxPro成为了一种灵活强大的客户机/服务器应用前端。利用远程视图和SQL提交两种方法提供的强大功能创建客户-服务器应用,以充分利用基于ODBC(Open Database Connectivity)的后台数据库(如Oracle和SQL Server)。
应用发展的巨大真实性之一就是做每件事都有很多的方法。在建立一个应用时最难做的事之一就是确定一个方法以及知道这个方法是否比其它所有的方法都好。在客户机/服务器的发展中,这个方法就是实际上是在混合处理两个数据库引擎,前端的Visual FoxPro和后端非常强大的SQL数据库引擎。
在这篇文章中,用Visual FoxPro建立的一个对象链接和嵌入服务器被用来创建三层客户机/服务器应用。加了一个中间层用来提供一个额外的空间存放代码和运行确认。
