The Computer Super Store A Sample Presentation Depicting the Requirements of Your Group Project

A (maximum) 10 minute presentation to the class. Class time, however, may limit the presentations to three groups (drawn by lot). Describe the physical problem and database design (the tables and relationships) that will be used to implement the system. Illustrate the type of information to be obtained from the system and the means of obtaining that information. The Assignment

Describe the System and Its Relationships Our system is intended to track the orders, customers, and products in a Computer store. There is a: – One-to-many relationship between customers and orders; one customer can have many orders, but a specific order is associated with one customer. – Many-to-many-relationship between orders and products; this requires the creation of another table that contains the primary key of both the Orders and Products tables

The Design Combination of OrderID and ProductID is unique

Information from the Database Query: What orders were placed by John Smith? Solution: Search the Customers table to determine John’s CustomerID, then go to the Orders table to find all loans for that CustomerID

Information from the Database Query: Which products appeared in order 1? Solution: Search the Order Details table for all records for Order 1; take the ProductID of those records to the Products table to learn product names.

Information from the Database Query: What is the customer’s phone number for Order 6? Solution: Search the Orders table for Order 6, then take the CustomerID to the Customers table to obtain the phone number.

A Contract Between You and Your Professor Your presentation becomes a contract between you and your professor with respect to the database design. Additional requirements will be specified later. The completed system must be able to add, edit, or delete any object through a form The completed system must be capable of creating your sample queries which in turn reflect any changes to the data

Delivering the Presentation Use PowerPoint to make the presentation as polished as possible. All members of the group are to be in front of the room during the presentation. Maintain eye contact, speak in sufficient volume, etc. Handouts of the printed relationships diagram are required for the class
