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 Data Sources button

button.

Project control tables are used to create the structure of the projects within a project control group. The tables must be registered as data sources in the SAS Management Console or a libref must be created to access tables on a local or network drive, before you create a project control table.

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:

project input tables
project output 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.

Note: An alternative to using prototype tables to define the project input and output variables is to copy the variables from the champion or challenger model, or to modify the project definition. For more information, see Modify Project Definition.

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

scoring task input tables
scoring task output tables
train tables
test tables
performance tables

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.
