Siebel Data Warehouse Architecture Components

---

The Siebel Data Warehouse architecture comprises the following components:

• Informatica Server. Initially loads the Siebel Data Warehouse and performs subsequent incremental loads. Depending on your business needs, you might incrementally refresh the Siebel Data Warehouse once a day, once a week, once a month, or other similar scheduling. When the server is loading or refreshing the Siebel Data Warehouse, it is recommended that the server be dedicated to that activity. However, when the ETL server is not loading or refreshing the Siebel Data Warehouse, you can use it for other purposes.
• Informatica Repository Server. Manages the Informatica repository.
• Informatica client utilities. Tools that allow you to create and manage the Informatica repository.
• DAC client. A command and control interface for the data warehouse to allow for set up, configuration, administration, and monitoring of data warehouse processes.
• DAC server. Executes the instructions from the DAC client. The DAC server manages data warehouse processes, including scheduling, loading of the ETL, and configuring the subject areas to be loaded. It dynamically adjusts its actions based on information in the DAC repository.
• DAC repository. Stores the metadata (semantics of the Siebel Data Warehouse) that represents the data warehouse processes.
