A. Design a data warehouse star schema for a dimensional database named QACS-DW. The fact table measure
Question:
A. Design a data warehouse star schema for a dimensional database named QACS-DW. The fact table measure will be Item Price.
B. Create the QACS-DW database in a DBMS product.
C. What transformations of data will need to be made before the QACS-DW database can be loaded with data? List all the transformations, showing the original format of the QACS and how it appears in the QACS-DW database.
D. Write the complete set of SQL statements necessary to load the transformed data into the QACS-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 QACS-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 QACS-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 Queen Anne Curiosity Shop database shown in Chapter 3 in a DBMS product, create and populate the QACS database now in the DBMS of your choice (or as assigned by your instructor).
