What is Entity Framework? It is a object relational mapper that allows us to interact with relational data using domain specific objects. This is where entity framework plays a vital role. Otherwise developers end up in writing lot of code to do this conversion. If a domain object from application layer needs be persisted as relational data then we need a mapper to convert domain object to relational data. So application layer and database layer has got two different standards for managing data. However, when it comes to data storage we use relational data and RDMS systems. It has got its own standards for managing object oriented data. What is the need of Entity Framework? Let me explain in simple words.The software application that we write using object oriented languages such as C#, java deals everything in terms of objects. Before we begin with development, let us understand few concepts. So let us move further and understand how can we build data access layer using entity framework. In my last article, I have explained how to create simple asp.net mvc application.
