Objectives
• Introduce Premiere Products, the
company that is used as the basis for
many of the examples throughout the text
• Introduce Henry Books, the company that
is used in the case that runs throughout
the text
Premiere Products
• Distributor of appliances, housewares, and
sporting goods
• Uses spreadsheet software to maintain
important data
• Recent growth has made the spreadsheet
approach problematic:
– Redundancy
– Difficulty accessing data
– Limited security
– Size limitations
Introduction to Henry Books
Database Case

• Henry decided to use database to gather
and store information on:
–

Exercise #5

•
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
• 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; 30 in 2006, 30 in 2007); 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.)
