Reviewing Cube and
Dimension Properties
After you have defined a cube, you can review
the results by using Cube Designer. In the following task, you review the
structure of the cube in the Analysis Services Tutorial project.
To review cube
and dimension properties in Cube Designer
1.
To open the Cube Designer, double-click the Analysis Services Tutorial cube in the Cubes node of Solution
Explorer.
2.
In the Measures pane of the Cube Structure tab in Cube Designer, expand the Internet Sales measure group to reveal
the defined measures.
You can change the order by dragging the
measures into the order that you want. The order you create will affect how
certain client applications order these measures. The measure group and each
measure that it contains have properties that you can edit in the Properties
window.
3.
In the Dimensions pane of the Cube Structure tab in Cube Designer, review the cube dimensions that are in the
Analysis Services Tutorial cube.
Notice that although
only three dimensions were created at the database level, as displayed in
Solution Explorer, there are five cube dimensions in the Analysis Services
Tutorial cube. The cube contains more dimensions than the database because the
Date database dimension is used as the basis for three separate date-related
cube dimensions, based on different date-related facts in the fact table. These
date-related dimensions are also called role playing
dimensions.
The three date-related cube dimensions let users dimension the cube by three
separate facts that are related to each product sale: the product order date,
the due date for fulfillment of the order, and the ship date for the order. By
reusing a single database dimension for multiple cube dimensions, Analysis
Services simplifies dimension management, uses less disk space, and reduces
overall processing time.
4.
In the Dimensions pane of the Cube Structure tab, expand Customer, and then click Edit Customer to open the dimension in Dimension Designer.
Dimension Designer contains these tabs: Dimension Structure, Attribute Relationships, Translations, and Browser. Notice that the Dimension Structure tab includes three
panes: Attributes, Hierarchies, and Data Source View. The attributes that
the Dimension contains appear in the Attributes pane. For more
information, see: Defining
Dimension Attributes,
Creating
User-Defined Hierarchies, Defining
Attribute Relationships
5.
Switch to Cube Designer by right-clicking the Analysis Services Tutorial cube in the Cubes node in Solution
Explorer and then clicking View Designer.
6.
In Cube Designer, click the Dimension Usage tab.
In this view of the Analysis Services Tutorial
cube, you can see the cube dimensions that are used by the Internet Sales
measure group. Also, you can define the type of relationship between each
dimension and each measure group in which it is used.
7.
Click the Partitions tab.
The Cube Wizard defined a single partition for
the cube, by using the multidimensional online analytical processing (MOLAP)
storage mode without aggregations. With MOLAP, all leaf-level data and all
aggregations are stored within the cube for maximum performance. Aggregations
are precalculated summaries of data that improve query response time by having
answers ready before questions are asked. You can define additional partitions,
storage settings, and writeback settings on the Partitions tab. For more
information, see Partitions
(Analysis Services - Multidimensional Data), Aggregations and Aggregation Designs, Designing Partition Storage and Aggregations
8.
Click the Browser tab.
Notice that the cube cannot be browsed because
it has not yet been deployed to an instance of Analysis Services. At this
point, the cube in the Analysis Services Tutorial project is just a definition
of a cube, which you can deploy to any instance of Analysis Services. When you
deploy and process a cube, you create the defined objects in an instance of
Analysis Services, and populate the objects with data from the underlying data
sources.
9.
In Solution Explorer, right-click Analysis
Services Tutorial
in the Cubes node and then click View Code.
The XML code for the Analysis Services Tutorial
cube is displayed on the Analysis Services Tutorial.cube [XML] tab. This
is the actual code that is used to create the cube in an instance of Analysis
Services during deployment. For more information, see: How to: View the XML for an Analysis Services
Project
10. Close the XML code tab.
