Program Interface Structure (135)

原创 IT综合 作者:tsinglee 时间:2007-11-03 20:12:11 0 删除 编辑

The program interface consists of the following pieces:
■ Oracle call interface (OCI) or the Oracle runtime library (SQLLIB)
■ The client or user side of the program interface (also called the UPI)
■ Various Oracle Net Services drivers (protocol-specific communications software)
■ Operating system communications software
■ The server or Oracle side of the program interface (also called the OPI)
Both the user and Oracle sides of the program interface run Oracle software, as do the
drivers.
Oracle Net Services is the portion of the program interface that allows the client
application program and the Oracle database server to reside on separate computers in
your communication network.

程序接口结构
程序接口结构由以下组成 :
1. Oracle接口调用(OCI) 或者Oracle运行库(SQLLIB)
2. 客户端或者用户侧的程序接口
3. 不同的Oracle网络服务驱动
4. 操作系统通信软件
5. 服务器端或者Oracle侧的程序接口
Oracle网络服务是程序接口中允许客户端应用程序和Oracle数据库服务能够驻留在separate computers in
your communication network.
