Developing and Deploying Siebel Business Applications > Creating a Virtual Business Component >
Understanding Virtual Business Components
Virtual business components (VBCs) bring data from external data sources into your Siebel application user interface. For example, you could create a VBC to represent data from data sources such as:
- Back office applications
- Legacy applications
- Transaction services
- Web sites
Virtual business components are based on business services. Business services determine the behavior of the VBC and define how the VBC manipulates data. You can base VBCs on predefined business services provided by Oracle, such as the XML Gateway, or you can create your own business service. You create both virtual business components and business services in Siebel Tools.
