Siebel Data Warehouse Installation and Administration Guide > Preinstallation Considerations for Siebel Data Warehouse > General Guidelines for Setting Up Siebel Data WarehouseThe Siebel Data Warehouse is a database that contains dimensional schemas. Although it is technically possible to put the Siebel Data Warehouse in the same database as the Siebel transactional database, it is not recommended for performance reasons. The Siebel transactional database is structured as an online transaction processing (OLTP) database, whereas the Siebel Data Warehouse is structured as an online analytical processing database. Each is optimized for its own purpose. The reasons for not combining the two databases are:
The Informatica repository stores all of the Informatica object definitions for the ETL mappings that populate the Siebel Data Warehouse. It is a series of repository tables that are stored in a database, which can be transactional, analytical, or a separate database. The Siebel Data Warehouse works with relational database management systems. In addition to the general requirements, there are additional database management systems (DBMS)-specific requirements depending on the DBMS you are using. The following general guidelines will help you set up the data warehouse physical database for performance and growth:
During the Siebel Data Warehouse configuration process, when you create the data warehouse tables using the procedure Creating Data Warehouse Tables, you can create tables in one tablespace and indices in another tablespace. However, for performance reasons, it is recommended that you create tablespaces as described in Table 8. |
