Version 1.0
Issue Date: April 2024


This unit describes the skills and knowledge required to understand business operations, identify entities and data, diagrammatically represent their relationships, and prepare a data model.

It applies individuals who have a broad range of analytical, technical and communication skills and who work within broad but established parameters.

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

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)


Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

ELEMENT

PERFORMANCE CRITERIA

Elements describe the essential outcomes.

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

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

Evidence of the ability to:

document client business requirements

construct an entity relationship diagram

construct and document a data model

normalise the model

validate the model.

Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.

To complete the unit requirements safely and effectively, the individual must:

fully describe:

database identifiers and their impact on database usability

normalisation rules and processes

type hierarchies, including sub-types, super-types and root-types related to development of structured data types

validation procedures and processes

describe the function and features of:

an approach to data modelling, such as the entity-relationship model

keys, e.g. unique keys, composite keys, primary keys and primary index

time stamps related to the use of keys

user defined types, structured types, reference types and user defined functions

data types and their application

summarise the particular business domain.

Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances must be typical of those experienced in the systems analysis and design field of work, and include access to:

client’s business requirements

special purpose tools, equipment and materials

industry software packages

computer aided software engineering (CASE) tools

entity relationship diagrams.

Assessors must satisfy NVR/AQTF assessor requirements.

Submission Requirements

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Assessors must satisfy NVR/AQTF assessor requirements.
Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
