What is a business component in Siebel and how is it used in application development?

A business component in Siebel is a reusable entity that represents a business object or concept, such as a customer or opportunity. It defines the structure and behavior of data associated with that entity, including fields, links to other business components, and business logic.

By leveraging business components, developers can easily customize the behavior of Siebel applications, implement complex business processes, and integrate with external systems. Business components provide a flexible and efficient way to manage data and business logic, making them indispensable in the development of robust and scalable Siebel applications.
