最近一直在找一种不用在最终客户机上安装Oracle客户端软件，直接访问Oracle数据库的方法。很多朋友都指点我，一般来讲，Oracle最好安装客户端软件。如果不想安装，那么大致有两种方法：
1。使用Midas三层结构，加应用程序服务器。
2。使用第三方控件，例如ODAC NET EDITION（http://www.crlab.com），后面是它的
介绍。
按照我现在参加的项目，第一种不太可能，但是第二种的控件，也不知道是因为只得到试用版的缘故，还是操作不当，仍然不能直接连接，不知道各位有没有用过，指点一下，多谢，多谢。
Advantages of Net option:
ODAC Standard as the most of applications which work with Oracle uses Oracle Call Interface to connect to Oracle database server. This is usual way to develop Oracle application with a third-generation language. As all OCI routines are in external libraries compiled application has small size. But it requires Oracle client software installed on workstation that is the cause of additional expenses for its installation and administration. Sometimes installation of Oracle client can be not advisable or even impossible. For example, if you need to set your application on remote machine where you don't have respective specialist.
ODAC Net allows your application to work with Oracle directly through TCP/IP protocol and doesn't require Oracle client software. To run your application built with ODAC Net it is only needed to have operation system and TCP/IP protocol support.
To connect to Oracle server with ODAC Net you need know the address of computer where Oracle server is, listening port number and database instance name.
