This essentially means that not so well-written can lead to very difficult situations when the application scope goes up or application faces certain design issues either in production or maintenance. In this article, I will list down most recommended design principles that you should keep in mind, while writing your classes. These design principles are called SOLID, in short.

They also make it easy for developers to easily refactor code, avoid code smells and are also a part of the agile or adaptive software development. SOLID design principles are : S - Single-responsiblity principle O - Open-closed principle L - Liskov substitution principle I - Interface segregation principle D - Dependency

Micro web services and Web services are two different concepts of application development architecture, Which can be differentiated from it's development style and layered architecture.In This article I will explain the difference between Web Services and Micro Services Web Services ?

For example, an application developed in Java can be used in C#, Android, Php etc., and vice versa.  Web Service is a connection technology, a way to connect services together into a S
