# Datasets (Deprecated)

Model your data in Sigma using datasets, or collections of data based on tables in your CDW or DBMS.

[Datasets](/docs/datasets) are deprecated:

* Starting June 2, 2026, you will no longer be able to create datasets or edit existing datasets.
* Starting September 15, 2026, you will no longer be able to use datasets as a data source or view datasets in Sigma.

Migrate your datasets to data models and update any documents that use datasets as a data source to use a different source. See [Migrate a dataset to a data model](/docs/migrate-a-dataset-to-a-data-model).

Datasets function as centralized, shareable data definitions and can include aggregations and other data manipulations. Admins define datasets that are used in workbook analyses as sources for visualizations, tables, and pivot tables.

Workbooks inherit all changes applied to underlying datasets, ensuring consistent, reliable metric calculations. When metric logic requires an update, you can apply the change in one location (the dataset), and all applicable workbooks automatically inherit and reflect the updated calculations.
