Data cube design template

If you select the Auto build check box, the wizard analyzes the data source view to configure the cube and its dimensions for you. The wizard identifies fact and dimension tables, selects measures to include in the cube, and builds hierarchies. On each page of the wizard, you can examine and change the choices that the wizard makes when Auto build is selected. If you do not select Auto build , you make all these choices manually. If you select Auto build , you can click Finish on any page of the wizard to jump to the last page and accept the default configurations for any remaining pages of the wizard.

On the last page of the wizard, you can review the structure of the cube before finishing the wizard. If you do not select Auto build , you must select the fact and dimension tables yourself. The wizard builds any dimensions that you choose to create, but you must use Dimension Designer to manually build user-defined hierarchies in the dimensions.

This requirement may not make any difference if you have already created the dimensions you want to use in the cube before running the Cube Wizard. If you use an existing data source to create a cube, the first step is to specify the data source view on which to base the cube. On the Select Data Source View page of the wizard, select an existing data source view.

In the preview pane, you can view the tables in a selected data source view. To display the schema for any selected data source view, click Browse. You can also click Add New Item on the File menu to add an existing data source view from another database or other location. For more information about creating data source views, see Data Source Views in Multidimensional Models.

A data source view must contain at least one table to be listed on this page. You cannot create a cube based on a data source view that does not have any tables.

In the Cube Wizard, use the Identify Fact and Dimension Tables page of the wizard to select the fact and dimension tables required to create the cube. If you selected the Auto build check box to create the cube, the fact or dimension tables the wizard detects are selected when this page first appears. If the wizard detects a table that is both a fact table and a dimension table, both columns are selected. If the wizard detects a table that is neither, neither column is selected.

If you do not need a table for your cube design, clear the Fact and Dimension check boxes. If you did not select the Auto build check box, you must make all the selections manually. Use the Tables tab or the Diagram tab:. The Tables tab lists the tables in table format. Select the check box in the Fact column or the Diagram column. The Diagram tab displays the data source view schema. Tables are color coded to indicate fact or dimension.

Click any table in the schema, and then click Fact or Dimension to select or clear the setting on that table. All the available time periods appear in the Time Periods pane of Dimension Designer. This pane replaces the Data Source View pane for dimensions that are based on dimension tables.

You can change the range of dates for a dimension by changing the Source time binding property setting for the dimension. Because this is a structural change, you must reprocess the dimension and any cubes that use it before browsing the data.

On the Specify Additional Calendars page of the wizard, select calendars on which to base hierarchies in the dimension. You can choose any of the following calendars. The calendar and settings you select determine the attributes that are created in the dimension. The wizard also creates calendar-specific hierarchies composed of the attributes that are created for the calendar.

For every calendar, each level in every hierarchy rolls up into the level above it. For example, in the standard month calendar, the wizard creates a hierarchy of Years and Weeks or Years and Months. However, weeks are not contained evenly within months in a standard calendar, so there is no hierarchy of Years, Months, and Weeks. In contrast, weeks in a reporting or manufacturing calendar are evenly divided into months, so in these calendars weeks do roll up into months.

Use the Define Dimension Usage page of the wizard to specify which cube measures are aggregated by each dimension in the wizard. The Dimension usage grid on this page lists the dimensions as rows and measure groups as columns. Select the check box for any dimension and measure group combination in which the dimension aggregates the measures of that measure group.

On the Completing the Wizard page, review the structure of the new cube and in the Cube name box, type a name for it. Optionally, select the Generate schema now check box to start the schema generation wizard. In most cases, you should not select this check box if you plan to create additional objects. You can also use Cube Designer to generate the schema later. Skip to main content. This browser is no longer supported.

Note The Define Time Periods page appears only if you include a time dimension in your cube on the Define New Dimensions page of the wizard. In this article. A value in this column defines the name of a measure in the cube. Click a value in this column to type a name. Click Add new measure in this column to create a new measure.

This column sets the Name property on the measure object. The name of the measure group that contains the measure. Click this value to either choose or type a name. If you delete all the measures that belong to a particular measure group, the measure group is removed as well. This column sets the Name property for the measure group object.

The data type for the measure. Click this value to change the data type. The cube will still successfully process though you will receive a warning , and for the data volumes in the AdventureWorksDW database it will perform adequately. For larger data volumes, you will need to address this warning. For more information on how to do that, consult the more complete SSAS text.

That was a lot of setup, but the payoff is pretty good too. It started when you chose your project type. Once you had your project put together, you had a few components to create on the way to browsing your cube. Dan Maharry is the editor of DeveloperFusion.
