“Design patterns” is a frequently spoken term in software development. There are about 30 design patterns so far, but not all of them are frequently practiced in the production. In this article I am going to list the design patterns I have found to be used very often in the software development.
i) Factory Pattern: This design pattern is found in the Junior developers’ code. Because the juniors are pretty much oblivious to the advance form of object encapsulation, the reason why it is their blind bet on getting the job done.
ii) Singleton Pattern: An abstract way of calling a class instance. It improves the application performance in a large development environment through the lazy initialization of a class.
iii) Decorator Pattern: Decorator pattern is the Senior Developers big bet on the Juniors’. Gives an extra .
iv) Observer Pattern: This one is my favorite. If you are familiar with concurrent application development, there is a chance that you know about this behavioral design pattern.
v) MVC Pattern : This is a very commonly used pattern in the web application development. Abstraction of “Model – View – Controller” is the center of attention in this design pattern. Most of the web application frameworks follow this design pattern.
