Chapter 2. Design Patterns – Making a Choice
When a software application development project is taken up, it is essentially thought of as a problem that requires a solution. When we start to develop the application, we start developing a solution specific to the given problem. Eventually, this solution may start getting reused in problems of a similar kind, and becomes a standard solution for solving such problems. As time passes, we see that a lot of problems that display the same pattern. Once we modify our standard solution to work on this observed pattern, we come up with a design pattern. Design patterns are no joke; they take years to produce, after being tried and tested for solving a great number of problems with a similar pattern.
The design patterns not only define the way in which we architect our software application, they also provide knowledge about what worked and what did not, while trying to solve a particular type of problem. There are times when no particular design pattern...
