# Database Providers

## Database Providers

Entity Framework Core can access many different databases through plug-in libraries called database providers.

* Database providers can extend EF Core to enable functionality unique to specific databases.
* Some concepts are common to most databases, and are included in the primary EF Core components.
* Such concepts include expressing queries in LINQ, transactions, and tracking changes to objects once they are loaded from the database.
* Some concepts are specific to a particular provider. For example, the SQL Server provider allows you to [configure memory-optimized tables](https://docs.microsoft.com/en-us/ef/core/providers/sql-server/memory-optimized-table) (a feature specific to SQL Server).

The following providers are supported in Entity Framework Core 5.

| Name                                            | NuGet Package                                                                                                     |
