Design and develop relational databases


Application

This unit describes the skills and knowledge required to design and develop a multi-table relational database (including queries, forms and reports) to meet a defined need using existing data and available digital database applications/platforms.

It applies to individuals who may work independently or within an administrative support role, with the responsibility to develop and use databases to store and retrieve data using commercially available applications/platforms.

No licensing, legislation or certification requirements apply to this unit at the time of publication.


Elements and Performance Criteria

PERFORMANCE CRITERIA

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.

2.5 Create password and access system according to organisational policies and procedures relating to data security

2.6 Access and use application help functions to overcome intermediate-level issues with database design and production, where required

3. Develop queries, forms and reports

3.1 Identify information output, database tables to be use and report layout, in accordance with task requirements

3.2 Identify data groupings, search and sort criteria, in accordance with task requirements

3.3 Run reports and queries to confirm that results and formulae produce required data

3.4 Modify reports to include or exclude additional requirements, where necessary

4. Test and finalise database

4.1 Populate database with sample dataset for testing, meeting organisational requirements for speed and accuracy
