When to Consider Design Patterns
Balancing practicality and over-engineering in software development
This week, at the study group, our engineer asked a question: Should we follow the design pattern to design and implement the project from the beginning?
The design pattern mentioned here refers to GoF’s Design Patterns.
Meanwhile, there is a related context which suggests that our coding should follow SOLID principle as much as possible, especially the first S and the second O, anyway.
Since SOLID principle should be followed as much as possible, then the design pattern should also be taken into consideration from the very beginning, right?
No, not really.
What are design patterns?
The design patterns we often talk about actually refer to those solutions defined by GoF, which are designed to solve the problems often faced in object-oriented programming.
When we want the code to be easy to maintain and easy to modify, i.e., the open and closed principle, we abstract the problems through various encapsulation…
