DbContext

An ORM uses the code representation of a SQL schema to request databases. Originally, they mapped a relational database. Now there's a lot of wrapper to map an ORM, with a lot of different data sources, such as noSQL databases, key-value pairs or documents, redis, document DB, CSV files, and so on.

With Entity Framework, a class that inherits the DbContext class maps the SQL schema.

This DbContext contains DbSet objects that map with DB tables.
