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.

  • Knowledge of GUI based database application. 
    		•

    UNIT STANDARD RANGE 
  • The design refers to all small to mid scale relational databases with a GUI.
  • This standard is applicable to any application that runs on any Graphical User Interface (GUI) operating systems.
  • Where wording is not exact for the chosen operating system or application, the learner can choose the equivalent item or option to demonstrate competence in the specific outcome or assessment criteria. 
    		•

    ASSESSMENT CRITERIA     

    ASSESSMENT CRITERION 1 
    A sub-query is created by using criteria resulting from another query. 
    ASSESSMENT CRITERION RANGE 
    Sub-query is created by amongst others checking values against a lookup table, comparing values against other values.
     

    ASSESSMENT CRITERION 2 
    A cross tab query is created by using specific tool provided by GUI relational database to pivot the existing data.

    ASSESSMENT CRITERION 1 
    A parameter query is created to constrain the result set by way of entering a constraint in a textbox. 

    ASSESSMENT CRITERION 2 
    A new field is created in a query by using an aggregation of existing fields by means of arithmetic calculations. 

    ASSESSMENT CRITERION 3 
    A new field is created in a query by using an aggregation of existing fields by means of text manipulation. 

    SPECIFIC OUTCOME 6 
    Create basic select queries using simple SQL syntax.

    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
