IT-330-X5595 Database Design and Management

Module 2 Assignment

Submit a systems analysis for your project, including a comprehensive entity-relationship diagram (ERD). Although you may use any tool to complete the ERD, it is strongly recommended that you use Microsoft Visio and then save the diagram into an image format (GIF or JPG) and then copy and paste the image into your design document. Remember to use the Books’R’Us scenario in the Milestone Two Guidelines and Rubric document to complete this activity.

All sections of this milestone should be compiled into a single Word document.

For additional details, please refer to the Milestone Two Guidelines and Rubric document in the Assignment Guidelines and Rubrics section of the course.

IT 330 Milestone Two Guidelines and Rubric

In Module Four, submit a systems analysis for your project, including a comprehensive

entity-relationship diagram (ERD).

Although you may use any tool to complete the ERD, it is strongly recommended that you use Microsoft Visio and then save the diagram into an image format (GIFor JPG) and then copy and paste the image into your systems analysis

.

All sections of this milestone should be compiled into a single Word document. Furthermore, all of Milestone One should be included in Milestone Two.Remember, this activity is based upon the scenario from your final project:

Scenario

Books’R’Us is a local bookstore that startedin 1978 in a small New England town. Books’R’Us has been able to withstand the challenges of larger bookstore chains, as well as the internet giant Amazon.com, by offering new and used books and other products in a comfortable location

that includes a café with free Wi

–

Fi. Books’R’Us recently purchased another local bookstore called Great Books, USA, from an owner who is retiring. Both businesses use a simple bookkeeping

system that includes Microsoft Excel.

The owners of Books’R’Us, Tom and Sarah Smith, would like a more efficient way to store inventory data and report on the various business essentials. They are

also preparing to offer e-commerce on their website. A consulting firm has recommended capturing information in a database and linking access tothe database

for each store. Tom and Sarah purchased Microsoft SQL Server to do this. The consulting firm has hired you to complete the database for Books’R’Us. In addition

to creating the database, you will provide a report for your supervisor at the consulting firm; this report should describe the rationale for and proposed development of the database.

Imagine that you have interviewed the store owners, Tom and Sarah Smith, and these are the questions with which they are mostconcerned:

1.How many books are sold each month by the publisher? This is important because quantity discounts are available from the publisher.

2.Which authors are the biggest sellers of books in our stores? This is important because the publisher offers discounts for certain authors each month.

3.What books are associated with each publisher?

4.What are the most popular products besides books that are sold in each store? In addition to books, the stores sell magazines, café-specific products like coffee and pastries, and various gift products.

5.From what region(s) (by ZIP code) do customers visit our stores? This is important because it will assist with future marketing efforts.

6.What customer data must be stored for the e-commerce portion of the website?

This milestone will be graded using the Milestone Two Rubric found on the following page.

The milestone should include the following:

·A comprehensive entity-relationship diagram (ERD)

This must include an appropriate set of attributes for each entity

.

·A relational model

Your relational model should be logical, should reflect strong understanding of the overall function of your database, and must comply with each of the requirements laid out in the ERD

.

·A functional dependencies diagram normalized into 3NF

Based upon the ERD you create, devise dependency diagrams and normalize the data into 3NF.

This step will require you to compile a collective list of all the functional dependencies in order to create the model.

The data in this section must reflect the

list of functional dependencies and must be accurately normalized into 3NF.

·A functional relational schema normalized into 3NF

Based upon the ERD and the dependency diagrams, create the relational schema and normalize the data into 3NF.

·A list of proposed queries

Based on the six questions that most concern the bookstore owners, develop a single query that will answer each question.
