Aim:

To give you practical experience in using Entity-Relationship and Relational Database modelling techniques.

Project Specification

The proprietors of WareMart Logistics have approached you and asked if you could design a database to help them manage their business. They would like you to create a conceptual data model of their business information requirements and would like to see how the model could be used to provide the answers to some commonly requested queries and reports.

WareMart has provided the following information that it believes may be relevant to your task:

• WareMart Logistics Pty Ltd operates a large warehousing and transportation business. It has a number of warehouses around the country.
• Each warehouse is referenced by a warehouse number, and WareMart would also like to record street, city, state and postcode details.
• Each warehouse has a number of employees and WareMart references them by use of a Staff ID. In addition they record surname, first name, date of birth, street, city, state, postcode and salary details.
• Each warehouse has a single manager and a manager is responsible for only one warehouse.
• Employees do not report directly to the manager but to a fellow employee who has been given supervisor status.
• Merchandise is stored in warehouse ‘locations'. Each location reference is made up of an aisle, shelf and bin number component. As an example you will find a carton of product number 123 (Printing paper) in location 13,2,1 which refers to aisle 13, shelf 2, and bin 1. WareMart wants to know the capacity of each location, as well as whether hazardous materials can be stored there.
• A product can be stored in more than one location within a warehouse and a location can hold more than one product.
• Products are assigned a department and each department is referred to by a department number. WareMart also stores the department name for each department. The other information WareMart requires for each of its products is the product number, a description of the product and its pack size
• WareMartrequires also the information on what quantity of each product is on hand at any given warehouse ‘location'. The location capacity and quantity on hand is in terms of the pack size of the product stored there.
• Clients are allocated a client number and this along with the client name is recorded. In addition each client has a main address, but may also have several others e.g. postal address, deliver-to address, etc. The individual address details recorded are: street, city, state, and postcode.
• A client may place several merchandise requests and WareMart needs to know the date a request was placed as well as the quantity for each of the products on that request. Once a request is placed a picking list is generated. Picking staff use this list to fill the client request. The picking list also has a spot for the employee to enter their staff id, the date the product was picked and the quantity picked from that specific location.

You are required to design (using an E-R diagram) an entity-relationship model of the problem, convert the model into a relational model, and assess the normal form of each schema.

Assignment Submission

You should produce a single pdf file, created using Word,containing all of the requirements as specified within this document. Your lecturer will provide details of how the fileis to be submitted within lectures.

The design document should contain:

1. A completed copyof the SITE Assignment Coversheet.
2. An appropriate title page that includes an acknowledgement of all students you have spoken to about the assignment.
3. A table of contents and automatically generated page numbers.
4. An entityrelation (E-R) diagram that models the problem which includes:
a. all entities,relationships (including names) and attributes;
b. primary (underlined) and foreign (italic)keys identified;
c. cardinality and participation (optional /mandatory) symbols;and
d. assumptions you have made,e.g.how you arrived at the cardinality/participation for those not mentioned or clear in the business description, etc.
The E-R should be completed using the standards of this course(crow'sfeet).

5. Normalisation of relations which identifies:
a. dependency diagram for each relation
b. the level of Normalisation achieved for each relation;
c. thereasons for any relation that is maintained NOT in 3NF.

6. Relational data structures that translate your E-R diagram which includes:
d. relation (table) names,
e. attribute (column ) names and field types (as required by WAMP),
f. primary and foreign keys identified;
The data structures should be shown using the standards of this course.

7. Abibliography,in APAformat,containing all resources used to complete the assignment. If no resources have been use d please indicate this appropriately.

Your assignment should be completed according to the University of Ballarat General Guide for the Presentationof AcademicWork.This isavailable onlineatthefollowing web address:
