What is the difference between the base table and extension table in Siebel?

In Siebel, the base table and extension table play crucial roles in defining the structure and functionality of the application. Understanding the differences between these two types of tables is essential for developers and administrators.

Base Table:

The base table in Siebel represents the core entity or object in the application. It contains the primary data fields and attributes that define the basic structure of the entity. Base tables are typically predefined and serve as the foundation for the application's data model.

Extension Table:

Extension tables in Siebel are used to extend the functionality of base tables by adding additional fields and attributes. These tables allow developers to customize and enhance the data model without modifying the base table directly. Extension tables maintain a one-to-one relationship with the base table and are linked through foreign key relations.

Differences:

• The base table defines the core entity, while the extension table adds additional fields and attributes.
• Base table structures are predefined, whereas extension tables are created to customize the data model.
• Changes to the base table affect all records, while changes to the extension table impact specific records or instances.

Overall, understanding the distinction between base tables and extension tables in Siebel is essential for designing a robust and flexible data model that meets the business requirements of the application.
