COIT11237 - Database Design & Implementation

General Information

Unit Synopsis

Relational databases are pervasive in information technology; designing and building these databases is a challenging yet rewarding occupation. This unit will introduce you to data modelling, relational database theory and normalisation. These are essential skills for the design and implementation of relational databases. The problems associated with poorly designed and implemented databases are demonstrated. The important database language SQL is covered in sufficient depth to allow you to appreciate its potential and limitations. Other topics covered in this unit include multi-user database processing and other front-end applications. During the unit, you will design and implement a small database application. The unit aims to give you a solid theoretical foundation while also providing you with an opportunity to apply the theory through the assignment work.

Note:- Students who are currently enrolled in or who have previously completed COIT12167 Database Use and Design cannot enrol in this unit.

Important note: Students enrolled in a subsequent unit who failed their pre-requisite unit, should drop the subsequent unit before the census date or within 10 working days of Fail grade notification. Students who do not drop the unit in this timeframe cannot later drop the unit without academic and financial liability. See details in the Assessment Policy and Procedure (Higher Education Coursework).

Attendance Requirements

All on-campus students are expected to attend scheduled classes – in some units, these classes are identified as a mandatory (pass/fail) component and attendance is compulsory. International students, on a student visa, must maintain a full time study load and meet both attendance and academic progress requirements in each study period (satisfactory attendance for International students is defined as maintaining at least an 80% attendance record).

Assessment Overview

Recommended Student Time Commitment

Each 6-credit Undergraduate unit at CQUniversity requires an overall time commitment of an average of 12.5 hours of study per week, making a total of 150 hours for the unit.

Assessment Tasks

Assessment Task Weighting
1. Written Assessment 30%
2. Written Assessment 30%
3. Examination 40%

This is a graded unit: your overall grade will be calculated from the marks or grades for each assessment task, based on the relative weightings shown in the table above. You must obtain an overall mark for the unit of at least 50%, or an overall grade of ‘pass’ in order to pass the unit. If any ‘pass/fail’ tasks are shown in the table above they must also be completed successfully (‘pass’ grade). You must also meet any minimum mark requirements specified for a particular assessment task, as detailed in the ‘assessment task’ section (note that in some instances, the minimum mark for a task may be greater than 50%).

Unit learning Outcomes

On successful completion of this unit, you will be able to:

  1. Differentiate database applications, systems, and their role in supporting business processes
  2. Demonstrate competency in using Structured Query Language
  3. Design models using a specified data modelling approach
  4. Create Relational Models
  5. Normalise tables using concepts relating to functional dependency
  6. Identify database implementation issues.

The aim of this unit is to provide an understanding of database theory, technology, the database environment, and the role of database applications in support of enterprise. The focus is the use and design of databases using contemporary technology—relational database technology and SQL. An introduction is provided to database implementation issues and emerging database technology.

Australian Computer Society (ACS) recognises the Skills Framework for the Information Age (SFIA). SFIA is in use in over 100 countries and provides a widely used and consistent definition of ICT skills. SFIA is increasingly being used when developing job descriptions and role profiles.

This unit contributes to the following workplace skills as defined by SFIA. The SFIA code is included:

  • Database Repository Design (DBDS)
  • Programming/Software Development (PROG)
  • Database Administration (DBAD)
