In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
This Unit Standard is intended for people who need to plan, produce and use small scale databases using a GUI based database application.

A person credited with this unit standard is capable to:
  • Demonstrating an understanding of relational database theory.
  • Analysing unstructured data not populated to a relational database model.
  • Creating queries using specific functions.
  • Creating different types of queries.
  • Creating parameter queries and adding calculated fields.
  • Creating basic select queries using simple SQL syntax. 
    		•

    LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    It is assumed that the learner is competent in the following:
  • Mathematical Literacy at NQF Level 3.
