ABAP’s Object Services — the Persistence Service and the Transaction Service — provide many advantages when developing software in ABAP. They open up ABAP programming to all the possibilities and advantages of object-oriented software development. For IOT GmbH, the fundamental concepts of Object Services have proven themselves entirely in practice, making our applications more robust, homogenous, and intuitive. Learn how using Object Services led to a clean division between database access and application logic, as well as considerable time-savings in development. The question of adding an integrated lock service to Object Services is also discussed.
