Model Dimension

Overview

The Model Dimension page maintains dimension definitions inside a data mart model. Use it to assign the dimension to a model, name and describe it, choose whether it is historicized, and maintain the attributes that belong to the dimension.

Function

Model selects the data mart model that owns the dimension. When the page is opened from a model's Dimensions branch, the model is preselected for new dimensions.

Name is the required technical dimension name. Friendly name and Description document the business-facing purpose of the dimension.

Historicized marks the dimension as historicized. When it is selected, the attribute key selector is hidden. When it is cleared, the IsKey column is available in the Attributes grid, and selecting one key attribute clears the key selection from the other attribute rows.

The Attributes grid defines the dimension attributes with a name, friendly name, and description. Save requires a model and name, stores the dimension and attribute rows, refreshes the navigation tree, and reloads the page. Cancel closes the page without continuing the current edit.

Access

Open an existing dimension from the Dimensions branch under a model in the navigation tree. Use Add dimension from the same Dimensions branch to create a new dimension for that model.

How to access

Models -> [model] -> Dimensions -> [dimension] -> Edit dimension, or Models -> [model] -> Dimensions -> Add dimension.

Toolbar

Data mart -> Models, then use the model's Dimensions branch in the navigation tree.
