Solid Design Principles

In this tutorial we will discuss SOLID design principles with simple real world examples.SOLID Principles Introduction 1. SOLID principles are the design principles that enable us manage most of the software design problems2. The term SOLID is an acronym for five design principles intended to make software designs more understandable, flexible and maintainable3. The principles are a subset of many principles promoted by Robert C. Martin4. The SOLID acronym was first introduced by Michael FeathersWhat is SOLIDS : Single Responsibility Principle (SRP) O : Open closed Principle (OSP) L : Liskov substitution Principle (LSP) I : Interface Segregation Principle (ISP) D : Dependency Inversion Principle (DIP)Single Responsibility Principle 1. Robert C. Martin expresses the principle as, "A class should have only one reason to change”2.Every module or class should have responsibility over a single part of the functionality provided by the software, and that responsibility should be entirely encapsulated by the classLiskov Substitution Principle 1. Introduced by Barbara Liskov state that “objects in a program should be replaceable with instances of their sub-types without altering the correctness of that program”2. If a program module is using a Base class, then the reference to the Base class can be replaced with a Derived class without affecting the functionality of the program module3. We can also state that Derived types must be substitutable for their base typesOpen/Closed Principle 1. “Software entities should be open for extension, but closed for modification”2. The design and writing of the code should be done in a way that new functionality should be added with minimum changes in the existing code 3. The design should be done in a way to allow the adding of new functionality as new classes, keeping as much as possible existing code unchangedInterface Segregation Principle 1. “Many client-specific interfaces are better than one general-purpose interface”2.We should not enforce clients to implement interfaces that they don't use. Instead of creating one big interface we can break down it to smaller interfacesDependency Inversion Principle 1. One should “depend upon abstractions, [not] concretions"2. Abstractions should not depend on the details whereas the details should depend on abstractions3. High-level modules should not depend on low level modules If we don’t follow SOLID Principles we 1. End up with tight or strong coupling of the code with many other modules/applications2. Tight coupling causes time to implement any new requirement, features or any bug fixes and some times it creates unknown issues3. End up with a code which is not testable4. End up with duplication of code5. End up creating new bugs by fixing another bug6. End up with many unknown issues in the application development cycleFollowing SOLID Principles helps us to 1. Achieve reduction in complexity of code2. Increase readability, extensibility and maintenance3. Reduce error and implement Reusability4. Achieve Better testability5. Reduce tight couplingSolution to develop a successful application depends on Architecture : choosing an architecture is the first step in designing application based on the requirements. Example : MVC, WEBAPI, MVVM..etcDesign Principles : Application development process need to follow the design principlesDesign Patterns : We need to choose correct design patterns to build the software
