For example, say we have a persistence class that handles database operations, and we see a change in that file in the GitHub commits. First of all, because many different teams can work on the same project and edit the same class for different reasons, this could lead to incompatible modules. This means that if a class is a data container, like a Book class or a Student class, and it has some fields regarding that entity, it should change only when we change the data model.įollowing the Single Responsibility Principle is important. To state this principle more technically: Only one potential change (database logic, logging logic, and so on.) in the software’s specification should be able to affect the specification of the class. The Single Responsibility Principle states that a class should do one thing and therefore it should have only a single reason to change.
OHAPI PRINCIPLES CODE
They all serve the same purpose: "To create understandable, readable, and testable code that many developers can collaboratively work on." Therefore, it is not a surprise that all these concepts of clean coding, object-oriented architecture, and design patterns are somehow connected and complementary to each other. Uncle Bob is also the author of bestselling books Clean Code and Clean Architecture, and is one of the participants of the "Agile Alliance". But the SOLID acronym was introduced later by Michael Feathers. Martin (a.k.a Uncle Bob) in his paper in 2000.
The SOLID principles were first introduced by the famous Computer Scientist Robert J. So grab a cup of coffee or tea and let's jump right in! Background Then we are going to get into the nitty-gritty details – the why's and how's of each principle – by creating a class design and improving it step by step. We will start by taking a look into the history of this term. This article will teach you everything you need to know to apply SOLID principles to your projects. So I believe that it is a topic that every developer should learn.
OHAPI PRINCIPLES SOFTWARE
These five principles help us understand the need for certain design patterns and software architecture in general. They are a set of rules and best practices to follow while designing a class structure. The SOLID Principles are five principles of Object-Oriented class design.
