+# Data Access
+
+ABP framework was designed as database agnostic, it can work any type of data source by the help of the [repository](Repositories.md) and [unit of work](Unit-Of-Work.md) abstractions. 
+
+However, currently the following providers are implements:
+
+* [Entity Framework Core](Entity-Framework-Core.md) (works with [various DBMS and providers](https://docs.microsoft.com/en-us/ef/core/providers/?tabs=dotnet-core-cli).)
+* [MongoDB](MongoDB.md)
+* [Dapper](Dapper.md)
+
+More providers might be added in the next releases.
