Category: Design Patterns

There are many different types of programming languages such as Functional, Procedural, Object-Oriented, Scripting, and Logic programming languages. Every type of programming language uses some sort of design patterns or strategies to solve common problems. In this context, Design Patterns are commonly and repeatedly used solutions for the design problems that software programmers face again and again. Design Patterns have been there for a long, but the famous book, “Design Patterns – Elements of Reusable Object-Oriented Software” by GoF classified 23 Design Patterns that are considered the foundation of Design Patterns for Object-Oriented Programming languages and widely used to solve common design problems. According to the book, every design pattern has four common elements that include the “Name” of the Pattern, the “Problem” to which it is applied, the “Solution” of the problem, and the consequences that are the result of the trade-off applying the Design Pattern to solve the problem.
