DB ADAPTER:-
3).
The Oracle Database Adapter is a JCA 1.5 connector, which runs on the Oracle
Application Server. It relies on an underlying JDBC connector/driver to enact
the database communication.
NOTE:- Any adapter can not talk database directly
Adapter talk to JCA Connection Factory like above picture
In 10G:-
If we create DB Adapter,it will generate Concrete WSDL with binding,JCA Binding instead of SOAP Binding.
In 11G:- In run time The JCA file and Abstract WSDL file much together and the Concrete WSDL file Generated on top of it.
TOP LINK LAYER :-
Top link layer file generated only for tables Operations Like SELECT, DELETE,INSERT AND UPDATE...........etc
If we want execute a PURE SQL Query, The TOP LINK LAYER is not generated.

1). The Oracle Database Adapter enables a
BPEL process to communicate with Oracle databases or third party databases
through JDBC. The Oracle Database Adapter service is defined within a BPEL
process partner link by using the Adapter Configuration Wizard of Oracle BPEL
Process Manager (Oracle BPEL PM).
2). The Oracle Database
Adapter enables Oracle SOA Suite and Oracle Fusion Middleware to communicate
with database end points. These include Oracle database servers and any
relational databases that comply with ANSI SQL and provide JDBC drivers.
