SET09107: Advanced Database Systems Coursework

Overview

This repository contains the coursework for the Advanced Database Systems module for the 2022/2023 Trimester 2. The coursework involves designing and implementing a database for a bank, focusing on capturing and utilizing object-relational features.

Scenario

A bank with branches across the UK needs a comprehensive database system to manage its branches, customer accounts, employees, and related information. The system should handle data related to branches, accounts, employees, and customers with specific requirements and relationships.

Database Schema

The database is designed with the following relations:

  • Branch (bID, street, city, p_code, bPhone)
  • Account (accNum, accType, balance, bID, inRate, limitOfFreeOD, openDate)
  • Employee (empID, street, city, postCode, title, firstName, surName, empHomePhone, empMobile1, empMobile2, supervisorID, position, salary, niNum, bID, joinDate)
  • Customer (custID, street, city, postCode, title, firstName, surName, custHomePhone, custMobile1, custMobile2, niNum)
  • CustomerAccount (custID, accNum)

Tasks

Task 1: ER Diagram

  • Objective: Draw an ER diagram corresponding to the relational database schema and scenario.
  • Deliverable: ER diagram image.

Task 2: Object-Relational Design

  • Objective: Re-design the database using object-relational features such as Structured Types, Inheritance, References, Methods, Constraints, and Collections. Provide a critical discussion on your design choices.
  • Deliverable: Detailed design description and rationale.

Task 3: Implementation

  • Objective: Implement the database according to the redesign and populate the tables with at least 15 rows of test data.
  • Deliverables:
    • DBCreating.sql: SQL script for creating types and tables.
    • DBPopulating.sql: SQL script for inserting data.
    • Test data examples.

Task 4: SQL Queries

  • Objective: Provide SQL statements and answers to specific queries. Output should be formatted and data should be displayed in values, not types.
  • Deliverables:
    • SQL scripts for each query.
    • Output results.

Task 5: Discussion

  • Objective: Critically discuss the advantages and disadvantages of the object-relational model compared to the relational model based on your designs and implementations.
  • Deliverable: Critical discussion.

Task 6: Drop Statements

  • Objective: Write a sequence of drop statements to remove all tables and types.
  • Deliverable: droppingTypesTables.sql.

Demonstration

  • Details: Demonstrate your implementation of Task 4.
