The National Bank Database 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 customers, loans and the associated payments for each loan. There is a: – One-to-many relationship between customers and loans – One-to-many-relationship between loans and payments

The Design

Query: What are the loans for John Smith? Solution: Search the Customers table to determine John’s CustomerID, then go to the Loans table to find all loans for that CustomerID Information from the Database

Query: What is the name and phone number of a customer with a specific loan? Solution: Search the Loans table for the loan to get the CustomerID, then search the Customers table for that ID and return the name and telephone

Information from the Database Query: What payments were made by Mary Jones? Solution: Search the Customers table to determine Mary Jones CustomerID, then go to the Loans table, find all loans for this customer, then go to the Payments table and list all payments associated with any of those loans.

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
