INFO6002: Database Management 2

Trimester 2, 2021 – Callaghan & Online

Assignment 2 – Database Design & Implementation

Blackboard Submission Due: 10pm, Friday 2

nd July 2021

Demonstration Sessions:

Callaghan students (Lab Session): 4 - 6pm, Wednesday 7th July 2021

Online students (via Zoom): 5 - 6pm, Tuesday 6th July 2021

WORTH 25% of final course mark.

This is an INDIVIDUAL Assignment.

Assignment Requirements

This assignment contains 5 parts. You will submit your work to Blackboard as well as

demonstrate your working scripts. For Callaghan enrolled students, you will demonstrate

during the Week 9 lab session. For Online enrolled students, you will demonstrate on Zoom

(5 - 6pm, Tuesday 6th July 2021).

Part 1: Revised Data Requirements, EER Model & Data Dictionary (2 marks)

In this section, you will revise your work from Assignment 1 based on any feedback given

by your lecturer. You will re-submit your:

A. Data Requirements

B. EER Model

C. Data Dictionary

Part 2: Relational Mapping & Normalisation (3 marks)

Next, the EER Model needs to be mapped to a relational schema and normalised.

The relational model needs to be documented in DBDL format. Sample DBDL format is given

in the below:

ISBN (id, number, itemNo)

Primary Key id

Alternate Key number

Foreign Key itemNo references Book(itemNo)

ON UPDATE CASCADE, ON DELETE CASCADE

DBDL format is provided in your text. (Databases Systems – A Practical Approach to

Design, Implementation, and Management – 6

th Edition by Connolly and Begg 2015).

Secondly, identify any relations that are not normalised and show the steps to transform

them into a normalised relation.

Part 3: Implementation – Database Script (5 marks)

Create a T-SQL script for the database design in Part 2. You will create a database with all

the necessary tables and constraints: primary key, foreign key, not null, unique and check

constraints. The database must be populated with sufficient and meaningful records for

evaluation.

Part 4: Stored Procedure (10 marks)

Implement the following stored procedures. Ensure that each stored procedure is tested with

appropriate sample data. Test cases should be saved in a separate test script.

(1) Create an order

Procedure name usp_createCustomerOrder

Description

This stored procedure creates a new customer order. The sales tax is 10% of order amount.

Input Parameters

Customer id – Id of customer

Items – A Table-valued Parameter (TVP) of items (item number, quantity,

discountPromotionCode). Note that the discountPromotionCode is null for items where a

discount does not apply or items are not part of promotion

FulfilmentType – Type of order fulfilment (delivery or pickup)

OrderType – Type of order (phone, walk-in, app, website)

Employee id – Employee id of employee taking the order. This will be null for an online

order

OrderDateTime – Date and time of order is placed

DeliveryAddress – Delivery address if it is a delivery order

ExpectedOrderFulfilmentDateTime – Date and time when the order needs to be fulfilled.

Output Parameter Order number of the newly created order

Functionality

Creates a new order with the provided input parameters. After each order, the ingredients

used for the order are deducted from the current stock levels of the ingredients. Returns

the newly created order number. If there is any error an appropriate error message is

raised.

SQL script create_usp_createCustomerOrder.sql

Test script test_usp_createCustomerOrder.sql

Section 5: Business Rule (5 marks)

Business Rule: Order Satisfiability

Before an order can be taken, it is important to verify that the order can be satisfied with the

available ingredients in the store. If the ingredients available are insufficient to fulfill the order

an appropriate error message needs to be generated and the order cancelled.

Ensure that the above business rule is enforced in the database. You need to generate

appropriate error messages if an attempt to violate the constraint is attempted.

Blackboard Submission Requirements

The following items need to be submitted to Blackboard at:

Assessment / ASSIGNMENT 2 / Assignment 2 Submission.

Submit a single .zip folder named as:

A2, your first name, your surname and your student number

e.g. A2SimonLee1234567.zip

The zip folder will contain the following files:

Description Format

Part 1A: Requirements

Document

Revised Requirements Document including Data

Requirements, Transaction Requirements & Business

Rules

The following T-SQL Script files must also be included in the .zip file:

SQL Script name Description

Part 3:

Implementation –

Database Script

createDB.sql

Contains the script that creates the

database along with all constraints. Also,

inserts sample data into the tables.

Part 4: Stored

Procedure

Contains T-SQL Script to create the stored

procedure.

test_usp_createCustomerOrder.sql

procedure.

Part 5: Business

Demonstration Requirements

Each student must demonstrate their working SQL Scripts during the week 9 lab session on

Wednesday 7th July 2021 from 4-6pm (Callaghan students) or Zoom session on Tuesday

6

th July from 5-6pm (Online students). Failure to attend the demonstration can result in a

zero grade for the assignment.
