# Data Source use cases

Domino data sources offer a mechanism to create and manage connection properties to a supported external data service. Both administrators and users create data sources, and share them among collaborators. Connection properties are stored securely and there is no need to install data source specific drivers or libraries. A tightly coupled library provides a consistent access pattern for both tabular and file based data. To learn more about data sources, see [Domino data sources](/cloud/platform-capabilities/core-concepts/data/data-source-connectors).

Here is a list of Data Source operations:
