Entity Framework Getting started with Entity Framework What is Entity Framework ?
Example
Writing and managing ADO.Net code for data access is a tedious and monotonous job. Microsoft has provided an O/RM framework called "Entity Framework" to automate database related activities for your application.
Entity framework is an Object/Relational Mapping (O/RM) framework. It is an enhancement to ADO.NET that gives developers an automated mechanism for accessing & storing the data in the database.
What is O/RM?
ORM is a tool for storing data from domain objects to the relational database like MS SQL Server, in an automated way, without much programming. O/RM includes three main parts:
- Domain class objects
- Relational database objects
- Mapping information on how domain objects map to relational database objects(e.x tables, views & stored procedures)
ORM allows us to keep our database design separate from our domain class design. This makes the application maintainable and extendable. It also automates standard CRUD operation (Create, Read, Update & Delete) so that the developer doesn't need to write it manually.
