About the Author: Bernard Aybout. I am a computer enthusiast. I have used and enjoyed computers since I was young and I enjoy teaching young minds how to code, because it teaches them how to think. Large-scale or expensive apps clearly require evaluation of design choices.

Still, software design directly impacts code reuse and longevity even for small-scale apps with limited overhead. This text evaluates and contrasts common object-oriented designs. A given problem may have many solutions. A developer may employ different design techniques — composition, inheritance, dependency injection, delegation, etc. A skilled developer can determine the costs and benefits of different design responses, even amid competing concerns.

A responsible developer documents design choices as a contract with the client, delineating external and internal responsibilities. To promote effective software design, this book examines contractual, object-oriented designs for immediate and sustained use as well as code reuse.

The intent of identifying design variants is to recognize and manage conflicting goals such as short versus long-term utility, stability versus flexibility, and storage versus computation. No one has a crystal ball; however, deliberate design promotes software longevity. With the prominence of legacy OO code, a clear understanding of different object-oriented designs is essential. Design questions abound. Is code reuse better with inheritance or composition?

Should composition rely on complete encapsulation? Design choices impact flexibility, efficiency, stability, longevity, and reuse, yet compilers do not enforce design and syntax does not necessarily illustrate design.
