-* **Remote Data Binding using UrlAdaptor**
+This section explains how to connect and retrieve data from a PostgreSQL Server database using [Npgsql EntityFrameworkCore PostgreSQL](https://www.nuget.org/packages/Npgsql.EntityFrameworkCore.PostgreSQL) and bind the data to a Blazor DataGrid component through the following methods:
+
+ **Using UrlAdaptor**
 
 The [UrlAdaptor](https://blazor.syncfusion.com/documentation/data/adaptors#url-adaptor) enables communication between the DataGrid and a remote API service connected to **PostgreSQL** Server. This approach is suitable when the API implements custom logic for data operations and returns results in the **result** and **count** format.

+**Using CustomAdaptor**
 
 The [CustomAdaptor](https://blazor.syncfusion.com/documentation/datagrid/connecting-to-adaptors/custom-adaptor) provides full control over data operations and CRUD functionality. It allows implementing custom logic for **searching**, **filtering**, **sorting**, **paging**, and **grouping** directly in the server-side code.
