 * **SQL** (or any other) **database** - you can find examples in our [online demos](https://demos.telerik.com/blazor-ui/grid/overview). You can see an offline version of the demos project in the `demos` folder of your installation ([automated]({%slug installation/msi%}) or [archive]({%slug installation/zip%})). They showcase an EntityFramework context using an SQL database that provides data to a grid through a service, which is a common architecture for decouping the front-end from the actual data source that you can apply to any database.
 
     * The **CRUD sample project** our extensions for [Visual Studio]({%slug getting-started-vs-integration-new-project%}) and [Visual Studio Code]({%slug getting-started-vs-code-integration-overview%}) can generate for you showcases a similar architecture that you can use as a starting point.

+    * The [Blazing Coffee sample application](https://github.com/telerik/blazor-ui/tree/master/sample-applications/blazing-coffee) shows how to provide data from a SQL (uses SQLite) database to the Grid using Entity Framework Core services.
 
 * **WebAPI** data source - you can see how to send an appropriate request for data and return an optimized query in the following sample projects: [Grid DataSourceRequest on the server](https://github.com/telerik/blazor-ui/tree/master/grid/datasourcerequest-on-server). This is a flexible approach that you can use for any type of service you have - serializing and deserializing the data according to the application logic and needs, and optimizing the database queries on the backend.
