In the past, the gap between the object and relational worlds has seriously hampered the use of ABAP Objects in application development. Instead of focusing on your application, you spent a considerable amount of time and effort designing and implementing a persistence framework to close this gap. Release 6.10 introduces Object Services, a framework for handling most persistence functions automatically and transparently. This article shows you how to use the Persistence Service to store objects in the database and the Transaction Service to control transactions, freeing you to focus on the business logic in your ABAP applications.
