Informatica 8.01之後提供以下6 種 API PowerExchange API, Transformation API,Operations API,Design API,Custom Function API。 用以實現不同的自動化功能。 下面提供一下Design API的代碼，用以實現自動連接Oracle數據庫，自動創建Source， Target, Mapping, Session和 Workflow。在自動創建ODS的方面比較有用。
Java 創建Mapping分爲以下幾步：
1.createRepository
2.createFolder
3.createSources
4.createTarget
5.createMappings
6.createSession
7.createWorkflow
8.generateOutput
