Program Interface Structure (135)

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.

程式介面結構
程式介面結構由以下組成 :
1. Oracle介面呼叫(OCI) 或者Oracle執行庫(SQLLIB)
2. 客戶端或者使用者側的程式介面
3. 不同的Oracle網路服務驅動
4. 作業系統通訊軟體
5. 伺服器端或者Oracle側的程式介面
Oracle網路服務是程式介面中允許客戶端應用程式和Oracle資料庫服務能夠駐留在separate computers in
your communication network.
