The Model Accelerator workspace

After you create a project, you start work in a Model Design Accelerator session. The Model Accelerator is the graphical workspace where you build your star schema.

To build your star schema, design the fact query subject using the measures that you want to include in your reports. Then, build model query subjects to provide context and describe those measures. The lines that join query subjects indicate that relationships exist. Use the Query Subject Diagram to view the data source tables that were used to create the selected query subject.

Model Design Accelerator evaluates each design step against modeling proven practices to identify and help you resolve potential issues. If your actions result in a potential issue, the Model Warning view displays.

After you complete your star schema, generate a model. You can refine the model in Framework Manager. Create a package and publish the model to the IBM® Cognos® Analytics server to begin authoring reports in the studios.
