Subject Title
Introduction to Database Design and SQL

Subject Description

This subject introduces students to relational database design and SQL (Structured Query Language) used with relational databases. Students will be introduced to  relational and object oriented models with a focus on the relational model and its operators. Students will be presented with a methodology for relational database design using Entity Relationship Diagrams and normalization of data. Students will be introduced to a subset of SQL using IBM's DB2 on the iSeries platform. An overview of the functions of the Database Management System (DBMS) and of a Database Administrator (DBA) will also be presented.

Credit Status
1 credit (3 units)
Required for CPA - Computer Programming and Analysis (Ontario College Advanced Diploma)
Required for CPD - Computer Programmer (Ontario College Diploma)

Learning Outcomes
Upon successful completion of this subject the student will be able to:

1. Use SQL to create and modify tables in DB2 databases

2. Work in groups on a project to design and create a DB2 database for an application requiring a minimum of 8-12 tables.

3. Merge normalized relations from each user view into a complete set of normalized relations for a simple business application

4. Prepare an Entity Relationship Diagram for a simple business application

5. Use SQL to retrieve data from DB2 databases

6. Prepare the physical relational database schema for a simple business application

7. Identify user views for an application

8. Normalize a user view to 3rd Normal Form

9. Be able to recover a previous database state using journaling commands

10. Describe the basic functions of a Database Management System

11. Describe the responsibilities of a Database Administrator in an organization

Mode of Instruction
Classroom lectures and discussions are supplemented by lab sessions with the instructor, reinforced by assigned readings and assignments between classess.

It is the student's responsibility to save documents, articles and notes that the instructor has provided on BlackBoard or in class. Students will not be able to access BlackBoard as of the last day of the student’s class.

Modes of Evaluation
Since this is a professional credit subject, marking standards reinforce professional practice by demanding legible, tidy work. Written materials should be well organized and grammatically correct, with proper spelling and punctuation.


  • Students must retain a duplicate of all assignments.
  • Computer assignments should be documented to the instructor's standards.
  • Assignments must be handed in on the scheduled due date. Late assignments are penalized.
  • For particulars, please obtain standards, dates, etc. from your instructor.

Absenteeism and Tests
