3-2 Copyright © 2006, Oracle. All rights reserved. Objectives After completing this lesson, you should be able to do the following: Review the logical model and source data used for the AW in this lesson Use the Analytic Workspace Manager tool to: –Create and populate an analytic workspace in the Oracle database –Describe and create multidimensional data types, including dimensions, measures, and cubes –Load data into the analytic workspace from a provided set of tables –View data in the analytic workspace

3-3 Copyright © 2006, Oracle. All rights reserved. Examining the Logical Model The AW includes: Dimensions: –Time –Product –Channel Measures: –Budget sales –Budget profit TimeProduct Channel Budget Sales and Profit

3-4 Copyright © 2006, Oracle. All rights reserved. Within the Channel and Product dimensions, a Total level exists as the highest level of summarization. Adding this highest level provides additional flexibility as application users analyze data. Examining the Logical Model: Dimensions Product Standard Channel Standard Time Calendar Dimension Hierarchy Total Category Subcategory Product Total Class Channel Year Quarter Month Levels

3-5 Copyright © 2006, Oracle. All rights reserved. Role of Cubes in Oracle OLAP A cube is a collection of measures that have similar characteristics. Measures in a cube: –Must have the same dimensionality –Are typically aggregated using the same rules across dimensions –Typically share sparsity patterns Cubes simplify the definition and administration of measures.

3-10 Copyright © 2006, Oracle. All rights reserved. Connecting to a Database To connect to a database, click the description name in the Databases node in the left navigator. Then, enter the username and password in the dialog box. Click OK.

3-11 Copyright © 2006, Oracle. All rights reserved. Creating an Analytic Workspace 1.Expand the schema node under which you want an analytic workspace. 2.Right-click Analytic Workspaces, and then select Create Analytic Workspace. 3.Enter a name for your analytic workspace

3-12 Copyright © 2006, Oracle. All rights reserved. Analytic Workspace: Creation and Maintenance Privileges To create and maintain an analytic workspace, you must have the following profile: OLAP_USER role SELECT privileges on the source schema tables Sufficient quota on the tablespace in which the workspace is created SELECT, INSERT, and UPDATE privileges for the table ( AW$table_name ) that contains the analytic workspace

3-14 Copyright © 2006, Oracle. All rights reserved. Creating Dimensions 1.Right-click the Dimensions folder, and then select Create Dimension. 2.On the default General tabbed page in the Create Dimension dialog box, enter TIME as the name, and then select Time Dimension as the dimension type. 3.Click Create

3-15 Copyright © 2006, Oracle. All rights reserved. Creating Levels 1.Right-click the Levels icon, and then select Create Level. 2.Enter the level name and labels. Click Create. Repeat the process for each level. 3.All levels are displayed
