About Siebel Tools

Siebel Tools is a Windows-based, object-oriented development environment for creating and customizing Siebel eBusiness Applications. Siebel Tools also provides a means for integrating programs written using Siebel scripting languages.

A standard Siebel application provides a core set of object definitions that you can use as a basis for your own tailored application. Siebel Tools object definitions are grouped into four layers with different purposes:

• Physical User Interface (UI) Layer: Templates and tags that render the UI.
• Logical User Interface Objects Layer: Presentation of data (UI).
• Business Objects Layer: Objects that extract defined information from the database or provide a defined service.
• Data Objects Layer: Database interface objects and table definitions.

Object types in a given layer depend on definitions in the next lower layer, and are insulated from other layers in the structure. This means, for example, that you can make changes to a Siebel application without changing the underlying database structure. Similarly, you can extend the Siebel Database schema without affecting the Siebel application.
