The level management feature allows you to design physical levels for tables.
Click the icon in the lower-left corner of the DataStudio page to go to the Setup page.
Table levels are used to define and manage the layers of data warehouses. In most cases, we recommend that you divide a data warehouse into various layers, such as the operational data store (ODS) layer, data warehouse detail (DWD) layer, data warehouse service (DWS) layer, and application data service (ADS) layer. Table categories allow you to categorize your tables in a finer-grained manner from the business dimension.
A workspace does not have default levels. Therefore, the workspace owner or workspace administrator must create levels based on their business requirements.
