Design Patterns in Object-oriented Abap

If a proven solution for a recurring problem already exists, why would you reinvent the wheel? This hands-on programming tutorial explains why and how you can use design patterns to help complete your ABAP tasks in less time with better code. Step-by-step, the author guides you through class and interface definitions, as well as the coding for all relevant methods. Plus, benefit immediately from extensively commented real-world code that shows how to implement MVC, Facade, Adapter, Decorator, and more in ABAP Objects. Implementation of Design Patterns Follow the implementation of Singleton, Adapter, Factory, MVC, Facade, Composite, and Decorator in ABAP. Hands-on Approach Written for practitioners, the book includes lots of code, detailed UML diagrams, and comprehensive explanations that guarantee quick success. Real-World Demo Application The code in this book is not just theory -- it's taken from a real-world application that implements all patterns shown in a production environment. Improving Code This book helps you improve the robustness and extendibility of your ABAP Objects code, while reducing maintenance efforts. New Coverage of Web Dynpro and the Factory Pattern This second edition has been thoroughly revised and expanded including a new chapter on the Factory pattern, and an extensive section on MVC implementation in multi-technology development for SAP GUI and Web Dynpro ABAP.
