And in the background, the business layer objects may interact with objects of some repository which in turn talks to some data source object or service object. Case Study Before we go ahead, let’s consider a Customer Order Management application that manages the orders placed by its customers for some products.
Code reusability has always been one of the major concerns for software developers. You do not ever want to write a similar code for two business problems. You would rather like to write the solution once and reuse it whenever and wherever required.
