Module 18: Case Study—Working with the Foodmart Database iii BETA MATERIALS FOR MICROSOFT CERTIFIED TRAINER PREPARATION PURPOSES ONLY Instructor Notes In this module, students apply concepts they have learned in modules 1 through 17 in the course 2074A, Designing and Implementing OLAP Solutions Using Microsoft ® SQL Server ™ 2000. Students will use various cube and dimension techniques to build cubes from the Foodmart 2000 database by using Microsoft SQL Server 2000 Analysis Services. In the labs, students are given high-level procedures and must recall the specific steps and actions for creating various dimension and cube structures. Students create a preliminary cube, and must then make changes to the cube by applying dimension and level properties. After completing this module, students will be able to: ! Create a cube based on user requirements. ! Create another cube with different dimensions and measures. ! Build a virtual cube.

Demonstration: 10 Minutes Module 18: Case Study—Working with the Foodmart Database ix BETA MATERIALS FOR MICROSOFT CERTIFIED TRAINER PREPARATION PURPOSES ONLY Other Activities Difficult Questions Below are difficult questions that students may ask you during the delivery of this module and answers to the questions. These materials delve into subjects that are within the scope of the module but are not specifically addressed in the content of the student notes. 1. How can you temporarily add 1997 inventory data to the Warehouse cube? You can incrementally update the Warehouse cube, defining the inventory_fact_1997 as the fact table from which to retrieve data. 2. What is an easy way to create the First Opened Year dimension in the Warehouse cube? In the Warehouse Cube Editor, create a new dimension by using the Dimension Wizard. Select the store table as the dimension table, create the dimension as a Time dimension, and then define the hierarchy containing two levels—year and month. At the end of the wizard, clear the Share this dimension with other cubes check box. After the dimension appears in the cube tree view, you can delete the month level, leaving one level, First Opened Date. Rename the level First Opened Year. x Module 18: Case Study—Working with the Foodmart Database BETA MATERIALS FOR MICROSOFT CERTIFIED TRAINER PREPARATION PURPOSES ONLY Module Strategy Use the following strategy to present this module: ! Building the Warehouse Cube Begin by defining the schema that students will use to build the Warehouse cube. Let students know which tables to use, and then introduce the dimensions and levels that they will create. Next, introduce the measures to include in the cube. Finally, define the calculated members to create. ! Building the Sales Cube Introduce the schema of the Sales cube. Let students know which tables to use. Next, introduce the dimensions and levels that they will create and then introduce the measures to include. Finally, define the calculated members to create. ! Building the Warehouse and Sales Virtual Cube Explain that students will be creating a virtual cube named Warehouse and Sales by combining the Warehouse cube and the Sales cube. Introduce the dimensions and levels to be included, and then define which measures to add. Finally, explain that students will add calculated members by using two different methods—creating a new one, and importing several from the source cubes. [...]...
