A. Design a data warehouse star schema for a dimensional database named JRJ-DW. The fact table measure
Question:
A. Design a data warehouse star schema for a dimensional database named JRJ-DW. The fact table measure will be Retail Price.
B. Create the JRJ-DW database in a DBMS product.
C. What transformations of data will need to be made before the JRJ-DW database can be loaded with data? List all the transformations, showing the original format of the JAMES_RIVER_JEWELRY data and how it appears in the JRJ-DW database.
D. Write the complete set of SQL statements necessary to load the transformed data into the JRJ-DW database.
E. Write an SQL query similar to the one shown in the text on page 456 that uses retail price as the measure.
F. Write the SQL view equivalent of the SQL query you wrote to answer part G.
G. Create the SQL view you wrote to answer part H in your JRJ-DW database.
H. Using either the results of your SQL query from part G (copy the results of the query into a worksheet in the JRJ-DW-BI.xlsx workbook and then format this range as a worksheet table) or your SQL view from part I (create a Microsoft Excel data connection to the view), create an OLAP report similar to the OLAP report shown in Figure 8-16. (Hint: If you need help with the needed Microsoft Excel actions, search in the Microsoft Excel help system for more information.)
If you have not already implemented the James River Jewelry database shown in the James River Jewelry Project Questions for Chapter 3 that is online in Appendix D in a DBMS product, create and populate the JAMES_RIVER_JEWELRY database now in the DBMS of your choice (or as assigned by your instructor). Note that this assignment uses SQL views, which are discussed in online Appendix E—SQL views.
