+# SharedDataSource Component
+
+A `Shared Data Source` in Web Report Designer is a reusable component that defines a connection to a data provider such as a database, web service, or file and can be used across multiple reports. Instead of configuring a data source separately for each report, you can create a shared one and reference it wherever needed.
+
+## Configuring a Shared Data Source
+
+To create a shared data source, locate an existing data source in the Web Report Designer. Click the ellipsis button (...) next to the data source and select "Save as Shared Data Source" from the context menu.

+
+After saving a data source as shared, the Web Report Designer generates a .sdsx file. This file represents the shared data source definition and can be opened directly in the designer for further configuration.

+
+## Difference Between Shared Data Source and Data Source
+
+In the Web Report Designer, both Data Source and Shared Data Source are used to define connections to external data. However, they differ in scope, usage, and maintainability.
+
+| `Data Source` | `Shared Data Source` |
+| ------ | ------ |
+| * Defined within a single report | * Defined outside of individual reports and stored as a .sdsx file |
+| * Cannot be reused across other reports | * Can be reused across multiple reports |
+| * Changes to the data source affect only the report where it is defined | * Changes to the shared data source affect all reports that reference it |
+| * Suitable for simple or one-off reports | * Ideal for centralized data management and large-scale reporting solutions |
