oday's customers demand easier-to-modify and more flexible applications than ever before. In this article, I will show you how to design applications with extensibility points so that they will grow with the clients' needs as well as provide a way to "swap" functionality in and out as needed.
Throughout my years in software development, many concepts and paradigms have been introduced to improve the process of writing code and defining how software should be developed. For the most part, each has built on its predecessors, enhancing the development process each time. Object-oriented programming redefined how developers think of and communicate with application entities. SOA showed how to expose object-oriented entities so they could service both similar and dissimilar clients. And the design-pattern craze hit the industry with the publishing of the famous GoF book. All together, these things have inspired the creativity of many developers, including me. I'm going to show you how to use your existing OOP and pattern knowledge to develop applications in a way that lets you change and/or enhance them with minimum effort and in a clean, elegant, and efficient manner.
