What are Design Patterns?

In software engineering, a software design pattern is a general, reusable solution to a commonly occurring problem within a given context in software design. It is not a finished design that can be transformed directly into source or machine code. Rather, it is a description or template for how to solve a problem that can be used in many different situations.

Design patterns can speed up the development process by providing tested, proven development paradigms. Effective software design must take into account problems that might not surface until later in the execution. Reuse of design patterns helps to eliminate minor flaws that can lead to large difficulties. Design patterns enhances code readability. Furthermore, patterns enable engineers to discuss software interactions using well-known, widely accepted terms.

To sum up Design Patterns in two words, I would say they are “Best Practices”. Design Patterns are nothing more than best practices for a particular problem you are facing. So, design patterns can help you become a better developer because you will be able to do the work much quickly saving both money and time.
