Model design
In the Model design pane of IBM® Cognos® TM1® Performance Modeler, you
create dimensions, cubes, and links to define the business logic for
an application.
The model design tab shows a summary of the steps needed to build models. The steps to build a model are as shown:
- Design dimensions
- To make the data available for input and analysis, you must first create dimensions. Some examples of dimensions are Chart of Accounts, Products, Time, and Versions.
- Build cubes
- Use the dimensions that you have defined to build cubes. A cube is a store of data within a model. It is multidimensional and contains rows, columns, and any number of pages. You use one or more cubes to create an application. Some examples of cubes are: Sales Planning or Expense Analysis.
- Link cubes
- Links establish a relationship that moves data from one cube to another. You can create links, for example, to reference assumption data in a planning cube.
- Create cube calculations
- Cube calculations simplify the creation of rules to complete common modeling operations, such as managing and maintaining the model. You can add a calculation to make your model meaningful by deriving more information from the data source.
- Create rules and processes
- Dimension calculations, cube calculations and links generate rules automatically and will generate feeders if this property has not been disabled for the server (by default it is on). Links can also generate processes. Optionally, you can create rules for advanced calculations, and processes for managing and maintaining the model. Processes can then be grouped into chores for ongoing maintenance.
