Difference between Code first, Model first & Database first

In this article we are going to discuss difference between Code First, Model First & Data Base First. These are the basic approaches used in Entity Framework.  



Code first

• popular in hardcore programmers.
• The database is used for data only.
• Manual changes to database will be lost because your code defines the database.
• Full control by code.

Database first

• Mostly used when Database is already created.
• If you want additional features in POCO entities you must either T4 modify template or use partial classes.
• Code is auto generated..
• The developer can update the database manually.

Model first

• We can create the database model.
• Extensible through partial classes
• Manual changes to database will be most probably lost because your model defines the database.
