Exercise #5 Use ACCESS, PP, and HB databases. Due: Mar 15 Points: 10 points Pratt & Adamski: Premiere Products [PP] and Henry Books [HB] Databases Use ACCESS, PP, and HB databases. Redesign both PP and HB databases as they would be for a data warehouse as described in Adamson & Venerable [Chapters 1 & 2] and Marakas [Chapters 1 & 2]. Use the Star diagram as the basis for their design. Be sure to include a meaningful Time dimension table. You are not asked to implement the DBs, i.e., the tables may be completely empty. Turn-in printouts of the REVISED relationship diagrams, i.e., the Star Diagrams, for both databases (deliverable 1) Turn in a list of 5 managerial questions for each case, that could be addressed with the help of the star schema (deliverable 2) On a separate page(s), clearly identify for each database: Fact tables, dimension tables, primary keys, foreign keys, alternate keys, etc. Use relational notation from Pratt & Adamski (deliverable 3). Indicate the normal form [1NF, 2NF, 3NF, etc.] of each table (deliv. 4) NOTE: Use the ORIGINAL copy of the Premiere Products and Henry Books databases for this assignment.

Exercise #6 Due: Mar 29 Points: 20 points Due: Mar 29 Points: 20 points Pratt & Adamski: Premiere Products and Henry Books [PP & HB]. Use the original DB files. Three deliverables (d1-d3) for each DB. 1. Generate the SQL Code needed to create the fact tables for both the PP and HB databases. Turn in the SQL statements (d1) BEFORE the make-table conversion. 2. Execute your SQL code and populate the fact tables. Turn in screen shots with the fact tables (d2) contents AFTER the make-table conversion. 3. Generate the ACCESS ERDs for both PP and HB. Arrange the entities to minimize cross-over lines. Adjust the primary and foreign keys to conform with our original database models. Turn in screen shots of both star schemas (d3) in Access relationship view.

Exercise #7 [TEAM PROJECT] p. 1 of 3 Due: April 5 Points: 30 points Pratt & Adamski: Premier Products Star Diagram Assignments must have cover sheet (deliverable 1), table of contents (d2), and indicate the NAMES OF ALL TEAM MEMBERS and the TEAM NUMBER. Assignments must be typed using a word processor (Word, WordPerfect) and have a professional look. Use of ACCESS is REQUIRED for this assignment. In this exercise you play the role of a regional DB Administrator in charge of your assigned territory (see p. 3). You are asked to type original transactional data and prepare them for a DW Load, to be performed in exercise #8. Part 7.1: Generate data for each of the following tables: Load Original Premier Product data into your Original Transactional Database. For your assigned territory: Create GOOD data for the following tables with at least as many new records as indicated: Rep (2 records); Customer (20 records); Part (10 records); Orders (60, all of them in 2013); OrderLine (120, at least one line for every order) Make sure that data types agree with case requirements. Dates must fall between 1/1/2013 and 12/31/2013. Change any dates in the case to conform to this standard (for example, if a date currently is 2010, change it to 2013. Turn in a printout of each table with data (d3). Note: Include the 5 tables listed above, not the fact table.

Exercise #7 [TEAM PROJECT] p. 2 of 3 Part 7.2: Revise your Design for the Premiere Products Data Warehouse using a Star diagram (more than one Star OK but not necessary). Include a meaningful Time dimension table. Create a NEW Access database .mdb file [PPex7TeamX.mdb], where X is your team #. Make sure all field types in the Dimension Tables and in the OrderDetail Fact Table agree with original case specifications, modified to accommodate new data field type. This is critical. Use the TIME table that is posted on the course Website (TimeTable2013). Turn in ACCESS ERD (deliverable 4) of revised Star Diagram Turn in Relation Listing (d5). On separate page, clearly identify: All relations, i.e., Fact tables, dimension tables, primary keys, foreign keys, alternate keys, etc. Use relational notation from Pratt & Adamski. E.g.: CUSTOMER[CustomerNum, CustomerName, …, RepNum] Turn in .mdb file (d6) (CD, email attachment, bring flash disk to the instructor, etc.)

Assignments must be typed using a word processor (Word, WordPerfect) and have a professional look. Use of ACCESS is REQUIRED for this assignment. Perform a Data Warehouse Load for Premier Products. Use your Star Diagram from Exercise #7 and populate the tables in the model with the new data available at the course Web site, combining all territories. Part 8.1 – Data Definitions: Use your Star Diagram from Exercise #7 and other necessary data definition documentation. Turn in a List of Relations (deliv. 3). On one (1) separate page, clearly list your fact and dimension tables using the simplified relational notation. E.g., EMPLOYEE [Eno, LastName, FirstName, … deptno, …] Be sure to include the TERRITORY data and add this field for every record in the ORDER_DETAIL table. Turn in a printed ACCESS ERD of your Star Diagram (deliverable 4). May be from previous homework.

Exercise #8 [TEAM PROJECT] p. 2 of 2 Part 8.2: Load data and print out your Fact and Dimension Tables. Load the data provided by the instructor into your tables. Note: Dates of all transactions should fall between 1/1/2004 and 12/31/2006 Turn in Transformation Maps (d6): Carefully document any data transfer and data cleansing activities that you performed. Note any data problems you encountered. Create the necessary DETAILED transaction Fact Table(s) that join all the dimension tables. You may use QBE or your SQL query from Exercise #6, appropriately modified. Turn in printouts of the contents of your fact and dimension tables (d7). Import into your word-processor Excel-type tables. Adjust their size and give them a professional look. Use landscape orientation, when necessary.
