openBuild uses 5 concepts around data manipulation.

* [Custom states](/working-with-the-framework/data-and-workflows/custom-states.md) - learn how to store data temporarily on a page.
* [Custom events](/working-with-the-framework/data-and-workflows/custom-events.md) - learn why we recommend using custom events.
* [Source Popup](/working-with-the-framework/data-and-workflows/source-popup.md) - learn how we centralize data management on a page.
* [CRUD](/working-with-the-framework/data-and-workflows/crud.md) - learn how to work smart and communicate with reusable elements.
* [Backend Workflows](/working-with-the-framework/data-and-workflows/backend-workflows.md) - why & when you should use them.
