Design databases

This unit describes the performance outcomes, skills and knowledge required to design and develop a database (including queries, forms and reports) to meet a defined need using existing data.No licensing, legislative, regulatory or certification requirements apply to this unit at the time of endorsement.


This unit applies to individuals employed in a range of work environments who create databases to store and retrieve data using commercially available database software. They may provide administrative support within an enterprise, or may be independently responsible for designing databases relevant to their own work roles.

1.4. Confirm database design with appropriate person

2. Develop database

2.1. Set field attributes according to data type and link databases by a common field in accordance with software procedures

2.2. Identify primary key to uniquely identify data

2.3. Identify foreign keys to establish associations between data

2.4. Use software functions and formulae to meet organisational and task requirements

2.5. Create password and access system according to organisational and task requirements

3. Develop queries, forms and reports

3.1. Develop queries as required by organisational and task requirements

3.2. Develop input screens or forms in order to access required data

3.3. Develop reports according to organisational and task requirements

4. Test and finalise database

4.1. Populate database with sample dataset for testing

4.2. Assess and document effectiveness of data relationships, queries forms and reports

Evidence Required

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment

Critical aspects for assessment and evidence required to demonstrate competency in this unit

Evidence of the following is essential:

producing a database containing a minimum of three tables and incorporating queries, reports and forms

knowledge of advanced functions of database software app.

Context of and specific resources for assessment

Assessment must ensure:

access to office equipment and resources

access to sample data.

Method of assessment

A range of assessment methods should be used to assess practical skills and knowledge. The following examples are appropriate for this unit:

direct questioning combined with review of portfolios of evidence and third party workplace reports of on-the-job performance by the candidate

review of databasedesign

review of database testing

demonstration of techniques.

Guidance information for assessment

Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:

IT use units

other IT analysis and design units.
