Logical Business Models

Using the Siebel Analytics Server Administration Tool, the administrator can create one or more logical business models in a repository. Business models are used to define and store business models and to provide the mapping of the business model to the underlying physical databases.

Logical Tables and Columns

Each business model contains two or more logical tables, and each logical table contains one or more logical columns. A logical table is an abstraction above a physical table. It can be a subset of a physical table (a subset of columns or a subset of rows); it can combine the contents of two or more physical tables; or it can be derived from other logical tables. Typically, logical tables reduce complexity in the information model because a single logical table can map to multiple physical tables.

Similarly, a logical column is an abstraction above a physical column. It can be mapped to one or more physical columns, to a scalar expression involving physical columns, or to other logical columns.

Heterogeneous Data Sources

The logical tables and columns can be mapped from multiple data sources. The data sources can originate from multiple databases of the same or of different types. For information about supported databases, see System Requirements and Supported Platforms on Siebel SupportWeb.
