![]() One class contains all logic related to pay calculation, database logic, and reporting logic. Additional classes may also need to be updated. It is possible that multiple members of the class may need to be changed when one reason to change occurs. However, this does not imply that you should limit your classes to just one method or property.Īs long as their responsibilities are related, a lot of members can be involved. The whole class should revolve around this single goal. It is important for developers to adhere to these principles to avoid "code rot," and instead to build applications that provide lasting value to customers and sanity for the future developers of the project.Īccording to the Single Responsibility Principle (SRP), a class should never be changed because of more than one reason.Įvery class, or similar structure, should only perform one function. With an extensive test suite, you can avoid code rot by using SOLID principles at a class-level, object-oriented design.Īn acronym for solid design consists of the following five principles: In this section, we give examples of each SOLID principle. To avoid maintenance and readability problems, it is preferable not to have tightly coupled code bases. Ī tightly coupled codebase is dependent on the other. Users can develop less coupled code by using SOLID principles. ![]() ![]() A solid design approach is a set of five principles in object-oriented programming that are designed to eliminate code rot and improve value, functionality, and maintainability.
