Background Information for Sample Database Project:

Australian Manufacturing Company (AMC) requires a database system to manage their stores, employees, products, suppliers, patrons and orders.
The following information has been gathered about current business activities of AMC.

  • AMC has many stores in different cities across Australia. Each store has unique store number and other details like name, contact details (phone number, email address and fax number) and location details (postal address composed of street number, suburb, state and postcode).
  • There are many departments within each store, for example, HR, accounts, finance and sales etc. each department is uniquely identified by department number. AMC also records department title, phone number and email address.
  • Each store has a number of employees. Each department is supervised by a department supervisor and each store is managed by a store manager who both are employees of AMC. Each department has a single supervisor only i.e. the department supervisor is also the supervisor for all the employees work within that department.
  • Each employee is referenced by unique employee number, name (first and last names), address, mobile number, email, TFN, salary and joining date. An employee s salary is recorded differently as per his or her employment type. Employees can be employed as fulltime or casual basis. For a fulltime staff, annual salary is recorded and hourly rate for a casual staff.
  • Each store creates payslips for all employees work in that store on a weekly basis. As a minimum payslip number, no of hours worked, employee detail, store detail and gross pay are recorded.
  • AMC sales different products like fashion, health, beauty, electronics etc. Each product is characterised by product number, name, brand, description and price.
  • Each product can be supplied by one or more supplier and each supplier can supply one or many products. AMC also keeps appropriate details of their suppliers.
  • Each store maintains an inventory of their products available for sale. The quantity of each product available in store and the quantity ordered are kept.
  • AMC patron visits the store and shops in the store. Each customer is characterised by customer number, name (first and last names), mobile number and address.
  • A patron may place orders. An order contains one or many products at a time. A store keeps track of order number, order date, product(s) ordered and quantity ordered for each product.

The proprietors of AMC have appointed your group as Database System Consultant to analyse, design and develop conceptual data model and physical database. They want a software/online application in future to be built on the database you design so that the operation of the AMC is greatly improved.
Your created models must accommodate the provided requirements. It is understandable that the provided information may not sufficient to create model that centralise all the data appropriately. You are free to make assumptions about their business activities if require. Make sure you record your assumptions.

System Requirements:

The system is a prototype system and as such is not a full production version. You will be required to enter a representative sample data into your tables in order to test the design and operation of your database.

Project Specification:

  1. Part A: Entity Relationship Diagram (20 marks)
  1. Your first task is to study the Case study requirements and gather as much knowledge to list all the main Entities and attributes.
  2. Create an Entity Relationship Diagram (ERD) to help you decide on the relationships.

Your entity relation diagram that models your database design should:

i. Include all entities, relationships (including names) and attributes.
ii. Identify primary and foreign keys.
iii. Include cardinality/ multiplicity and show using cro s feet or UML
iv. Include participation (optional / mandatory) symbols if applicable’

2. Part B: Normalisation (5 marks)

  1. Normalise all entities and relationships in optimal normal form. Provide the normalised schema and discuss the level of normalisation achieved for each relation. You goal should be normalise all entities in 3NF. Provide the reasons for any relation that is not maintained in 3NF.

Part C: Relational schema and PostgreSQL database (20 marks)

  1. Create relational schema that matches ERD and normalised schemas you created in Part A and B. The schema should include suitable data validation, integrity and referential integrity constraints, for example, types and length of attributes, primary and foreign keys etc. Make sure you follow standards, naming conventions and notation. (5 Marks)
  2. Using PostgreSQL, you are required to develop a demonstration prototype system (database) that stores data for AMC stores, employees, products,suppliers, patrons and orders. Create a new database called AMCDB. Create tables according to your relational schema created in step 1. (10 Marks)

Follow a standard naming convention for table names and also field names. Avoid using spaces and any special characters in table and field names. Use
underscore_case or use camelCase to separate parts of a name.
You are required to be consistent in tabl name, fiel name, data types, field
size and key constraints with relational schema created in step 2.

3. Add at least three records into each table. (5 Marks)

4. Part D: SQL (24 marks)

Use the AMCDB database that you created in PostgreSQL to design and execute SQL queries that answer the following questions.

Number your answers to each question clearly. The answer to each question must be tabulated as shown in the example below and include the SQL statement and also the output that is produced when you execute the statement in your database. The output includes the records that are listed and also the message that appears when you run the SQL statement.

For example:
Question 1:

Do not use screen captures to display the SQL statement or the output.
You should right-click on the PostgreSQL Command Prompt window; choose SQL statement and Output, to Copy and then Paste into your Word document that includes the answers to all questions.
Format and indent the clauses in your SQL statements for better readability and understanding as shown in the example above. Statements must be syntactically and semantically correct.

Format both the SQL and also the Output in Courier New 10 or 11 point.

  1. List the full name of Patrons, phone number and address in the descending order of customer number. The full name is comprised of first and last name joined with single space. Use the alias Customer full name for the composed column heading. (2 marks)
  2. List all the products having price less than $100. (2 marks)
  3. List the product number, product title, quantity ordered, unit price and total amount per product (unit price * quantity ordered) for order having order number 1005. (3 marks)
  4. List name, full address and fax number of stores that has the word George anywhere in the street component of address. Your query should consider the case sensitivity of the street as well i.e. the stores with words George , GEORGE , george , Geo etc. in street should be returned by your query too. (2 marks)
  5. List all the orders having at least two different products ordered. (2 marks)
  6. List customer number, name and address of all the customers who has not placed any order. (2 minutes)
  7. Retrieve first name, last name and employee number of all the employees along with department name and store name where they work. (3 marks)
  8. For each store, display store name and number of employees works in account department. (2 marks)
  9. List all the orders placed for financial year 2018 i.e. orders placed after 30/06/2017 and before 01/07/2018. (2 marks)
  10. Retrieve customer number and the total number of orders placed by each customer. (2 marks)
  11. For each order, retrieve the order number, order date and number of products ordered in it. Sort the output in descending order of order number. (2 marks)

5. Part E: Individual Personal Report, and 5 minutes video presentation, including presentation slides – Every group member needs to write/make this part individually and add to the documentation/submission (25 marks)

  1. Make a 5 minutes individual video presentation, including presentation slides, and Write a page to the AMC proprietors as a personal reflection that describes your experience building the database, and your contribution to your group project. You can
    discuss any challenges / difficulties that you experienced or solutions that you found. Comment on any limitations and / or strengths of your database design. Comment on whether your database meets all the system requirements as specified in Project Specification. Avoid making excuses or comments that reflect negativity. Include an
    acknowledgement of all students you have spoken to about the assignment. (15 marks)
  2. Students are also required to present your work in the class. The video presentation + Q&A can be around 5 to 10 minutes long. (10 marks)

    6. Part F: Report Layout, SQL script and presentation (6 marks)
  1. Deliverables for Parts A, B, C, D and E must be printed as a report with a cover sheet attached. See Administrative Details on page 10 for more details. Your report must include header and footer that include all the group membe name and student number, unit name, assignment name, and page numbers. Your report must be checked for spelling and grammar. Your report must also be formatted so that it is well set out and easy to read.

a) Each group must submit a single zip file on Moodle which contains all the
assignment files (single word file with deliverables for parts A D, separate personal reports for each group member, PostgreSQL script notepad file and individual 5 minutes video presentation, including slides).

b) The SQL that can be used to restore your database should also be uploaded to Moodle. You can create the SQL for your database as follows:
Create a text version of the database. Create PostgreSQL file that contains a list of SQL statements which can be used to restore/recreate the original database.
