What is the difference between vbc and ebc in siebel

I have come across a situation in siebel 7. In siebel 6 we are using virtual business component to populate the data into field though pickmap. Messenger Version 8. Get it NOW. VBCs: VBCs are the mechanism in siebel eAI by which data from an external system can be viewed in siebel application without having to replicate that data within the siebel database.

For ex: your users could access detailed credit card information from a mainframe system for a given customer account and see it displayed in siebel application interface. In this case, the basic customer account data such as account number, name is stored in siebel application while the detailed transaction information on that customers credit card account is stored in an external database.

VBCs are configured in Siebel tools and use Business Services to access data from an external system. EBCs: The external business component feature provides a way to access data that resides in a non-Siebel table or view, using a Siebel business component. Siebel Remote is not supported. EBCs support many-to-many relationships with the limitation that for such relationships the intersection table must be from the same data source as the child business component.

The Id field must be mapped to an underlying column in the external table in order to support insert, update, delete, and query operations.

Using the Oracle Sequence Object to populate the Id system field is not supported. The value of the Id system field has to be known by the object manager at the record commit time, while the Oracle Sequence Object value is populated by the database server when the change is being processed inside the data base.

If the column that was mapped to the Id system field has Primary Key checked, then rowid values are generated by the object manager. Otherwise, a user-entered rowid value is assumed, and the object manager does not generate a rowid value for it. For EBCs that contain multi-value groups, if a primary join is enabled, then both the parent and the child business components must be from the same data source.
