Auto-Parts Warehouse
Auto-Parts Warehouse is a small auto parts supplier with locations in several Midwestern metro areas. The business is based on the idea of discount prices for auto parts that are always in stock or can be delivered within hours. The owners have decided to computerize their operations to allow them to better track their business and manage their inventories for just in time deliveries for sales. Data to be gathered for each customer sale includes invoice number, date, parts number, cost, retail price. Customer data is collected that includes basic contact information and vehicles owned, which includes vehicle make and model. For parts that have to be delivered to the store to fulfil a customer purchase, a transfer request is created. Data associated with these transfers include tracking number, invoice number, date, parts number, origination location (store or warehouse) number, destination store number.

ASSIGNMENT STRUCTURE
- Cover Page
In this assignment cover page usually includes course code and name, semester, assignment title, student name, and student ID.
- Abstract
Abstract is one of the important parts of reports, research papers, and academic assignments. The abstract is often the last item that you write, but the first thing people read when they want to have a quick overview of the whole paper. I suggest you leave writing the abstract to the end, because you will have a clearer picture of all of your work.
A good abstract should has one well-developed paragraph that is coherent and concise, and is able to stand alone as a unit of information covers all the essential academic elements of the full length paper, namely the background, purpose, focus, methods, results and conclusions contains no information not included in the paper.
- Table of Contents
The table of contents usually includes the titles of the first-level headers, and often includes second-level or section titles (A-heads), and occasionally even third-level titles (subsections or B-heads).
- Introduction
In this assignment introduction usually includes the following: 1- Case study background
2- What is the report about?
Task 1:
You need to draw ERD for Auto-Part Warehouse that including the types of relationships between the entities.
(You need only to draw a diagram)
- Task 2:
For each of the entities identified, design tables and identify the possible candidate keys, the primary key, a probable foreign key, and potential secondary keys.
a) First you need to identify the entities that related to the Auto-Part Warehouse system.
b) Create a table to each entity that you identify as shown below: For example; one of the entities that you identify is Parts.
The possible Keys
Candidate keys
Primary key
Foreign key
Secondary keys
- Task 3:
Create fully normalized 3NF table designs for the system.
Create 3NF table designs should include all the entities that you identified in Task 2.
- Task 4:
Suggest ways Auto-Parts Warehouse can use codes to simplify output, input, and data formats.
Students' answers may include part numbers as an obvious use of codes for a retail store. Invoice numbers would be an example of sequence codes. A full discussion of codes can be found on pages 381 - 384.
