Object Types in Integration PLSQL API using OA Adapter

If you are planning to use plsql API with plsql collection parameters for any integration using OA Adapter / DB Adapter then use Object Types rather than plsql collections (ie tables and records).

Advantages are

1. Adapter can not use plsql tables and records directly. It will create similar database Object Type and use that in xsd creation, transformation etc. It also creates package to assign plsql collection into object types. This can be avoided if we use database object.
2. If there are any changes then just we need to change the object type and respective xsd. If we use plsql tables and records then we have to make changes in too many places. Some time it creates major issues in particular if we have complex transformations and assignments.
