Version 1.0
Issue Date: March 2024


This unit applies to database administrators and designers who are required to design databases.

This unit describes the performance outcomes, skills and knowledge required to establish client needs and technical requirements and to design a database that meets those requirements.

No licensing, legislative, regulatory or certification requirements apply to this unit at the time of endorsement but users should confirm requirements with the relevant federal, state or territory authority.

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

Prerequisites

Employability Skills

This unit contains employability skills.




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.

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:

design a well-structured database that represents the client's business reality and provides the user with a productive business tool.

Context of and specific resources for assessment

Assessment must ensure access to:

current industry-accepted database software, network or other system for remote or multi-user access

business requirements

CASE or diagramming software

appropriate learning and assessment support when required

modified equipment for people with special needs.

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 liaising with client

verbal or written questioning to assess candidate’s knowledge of:

normalisation

indexing

security models

review of the final database and associated support documentation.

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.


Submission Requirements

List each assessment task's title, type (eg project, observation/demonstration, essay, assingnment, checklist) and due date here

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.

Required skills

analytical skills to determine data objects required, data structures and business requirements

communication skills to liaise with clients

literacy skills to:

produce database documentation

produce models

numeracy skills to calculate field lengths, table and database estimated size

planning and organisational skills to undertake business analysis

problem-solving skills to solve normalisation problems

technical skills to undertake data modelling and structured query language (SQL) programming.

Required knowledge

data analysis, particularly in determining data types and data structures and query and report design

data modelling related to developing the conceptual data model

data redundancy

database management system (DBMS) fundamentals, particularly during the design phase

encryption and authentication as they apply to database security features

function and features of data types and data structures

functions and features of databases

logical design concepts, particularly related to designing data structures, queries screens and reports

object model design concepts, particularly related to designing data structures, queries, screens and reports

scalability of databases.

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. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Client may include:

employees

external organisations

individuals

internal departments.

Database may include:

commercial off-the-shelf (COTS) database packages

object-relational databases

proprietary databases

relational databases.

Technical requirements may relate to:

business

database

network

people in the organisation

platform

system.

Documentation may include:

audit trails

data dictionaries

entity-relationship diagrams

International Organization for Standardization (ISO), International Electrotechnical Commission (IEC) and Australian Standards (AS) standards

naming standards

project management templates and report writing principles

version control.

Database management system may include:

distributed or centralised

online

partitioned geographically or thematically distributed.

Requirements may relate to:

business

database

network

people in the organisation

platform

system.

Security plan may include:

authentication

authorisation and integrity

security objectives of the organisation.

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.
