Database First Approach is an alternative to the Code First and Model First approaches to the Entity Data Model which creates model codes (classes,properties, DbContextetc) from the database in the project and that classes behaves as the link between database and controller.
There are the following approach which is used to connect with database to application.
- Database First
- Model First
- Code First
Database first is nothing but only a approach to create web application where database is available first and can interact with the database. In this database, database is created first and after that we manage the code. The Entity Framework is able to generate a business model based on the tables and columns in a relational database.
