Conquer your fear and anxiety learning how the concepts behind object-oriented design apply to the ABAP programming environment. Through simple examples and metaphors this book demystifies the object-oriented programming model.
Object-Oriented Design with ABAP presents a bridge from the familiar procedural style of ABAP to the unfamiliar object-oriented style, taking you by the hand and leading you through the difficulties associated with learning these concepts, covering not only the nuances of using object-oriented principles in ABAP software design but also revealing the reasons why these concepts have become embraced throughout the software development industry. More than simply knowing how to use various object-oriented techniques, you´ll also be able to determine whether a technique is applicable to the task the software addresses. This book:

Shows how object-oriented principles apply to ABAP program design

Provides the basics for creating component design diagrams

Teaches how to incorporate design patterns in ABAP programs

What You´ll Learn

Write ABAP code using the object-oriented model as comfortably and easily as using the procedural model

Create ABAP design diagrams based on the Unified Modeling Language

Implement object-oriented design patterns into ABAP programs

Reap the benefits of spending less time designing and maintaining ABAP programs

Recognize those situations where design patterns can be most helpful

Avoid long and exhausting searches for the cause of bugs in ABAP programs

Who This Book Is For

Experienced ABAP programmers who remain unfamiliar with the design potential presented by the object-oriented aspect of the language

James E. McDonough received a degree in music education from Trenton State College. After teaching music for only two years in the New Jersey public school system, he spent the past 35 years as a computer programmer while also maintaining an active presence as a freelance jazz bassist between New York and Philadelphia. Having switched from mainframe programming to ABAP 20 years ago, he now works as a contract ABAP programmer designing and writing ABAP programs on a daily basis. An advocate of using the object-oriented programming features available with ABAP, he has been teaching private ABAP education courses over the past few years, where his background in education enables him to present and explain complicated concepts in a way that makes sense to beginners.
