Overview of Data Sources

Data sources are prototype tables and data tables that reside in the SAS Metadata Repository or in a SAS library on a local SAS Workspace Server or network drive, and are used by SAS Model Manager. You can view all registered data sources in SAS Model Manager by clicking the Data Sources category view button.

You can use prototype tables to import the input and output variables that SAS Model Manager uses to define projects. SAS Model Manager does not use any data in a prototype table except for the variable definitions. Data tables contain the data that you use to train or validate models, test models, and create reports that monitor the performance of a champion model in production.

The following tables are prototype tables:

If you use prototype tables to define project input and output variables, the tables must be registered as data sources in SAS Management Console or a libref must be created to access tables on a local or network drive, before you create a project.

Use the following data tables to train or validate models, test models, and create monitoring reports:

The scoring task input table and the scoring task output table must be registered as data sources or accessible with a libref before you create a scoring task.

Tables can be registered only by a user who has Write access to the SAS Metadata Repository. After you create a table, it must be registered in the SAS Metadata Repository using SAS Management Console or you must define a libref using the Edit Start-up Code window to be able to access the table using SAS Model Manager.

After tables are accessible, you can view them through the SAS Model Manager Data Sources category view.

For information about registering data sources, see the SAS Model Manager: Administrator's Guide.
