Description
This unit describes the performance outcomes, skills and knowledge required to understand business operations, identify entities and data, diagrammatically represent their relationships and prepare a data model.
Notes
Elements and Performance Criteria
1. Identify entities and relationships
  • 1.1 Analyse business data to understand operations
  • 1.2 Identify boundaries of the system
  • 1.3 Identify entities, attributes, data types and relationships of data
  • 1.4 Review business rules to determine impact
  • 1.5 Document relationships in an entity relationship diagram
2. Develop normalisation
  • 2.1 Identify suitable business data
  • 2.2 Undertake normalisation of business data and document results
  • 2.3 Compare normalisation results with entity relationship diagram
  • 2.4 Reconcile differences between data
3. Validate model
  • 3.1 Validate data model with client
  • 3.2 Resolve issues or recommendations
  • 3.3 Document completed data model
  • 3.4 Submit to client for final approval
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below.

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 ability to:
model valid data objects
normalise the model
validate the model.
Context of and specific resources for assessment
Assessment must ensure access to:
appropriate learning and assessment support when required
modified equipment for people with special needs
client business requirements
database software
computer-aided software engineering tools or other suitable software.
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:
observation of candidate’s use of computer-aided software engineering (CASE) tool or other appropriate software
verbal or written questioning to assess candidate’s knowledge of:
data modelling techniques
normalisation
entity relationship diagrams
review of completed data model and associated documentation prepared by candidate.
Guidance information for assessment
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, where appropriate.
Assessment processes and techniques must be culturally appropriate, and suitable to the communication skill level, language, literacy and numeracy capacity of the candidate and the work being performed.
Indigenous people and other people from a non-English speaking background may need additional support.
In cases where practical assessment is used it should be combined with targeted questioning to assess required knowledge.
