ICAB4136B Use structured query language to create database structures and manipulate data
Assessment tool
Version 1.0 Issue Date: March 2024
This unit defines the competency required to use a structured query language (SQL) to define, create and manipulate database structures and associated data in a relational database.
The following units are linked and form an appropriate cluster:
No licensing, legislative, regulatory 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.
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 following is essential:
Assessment must confirm the ability to use a structured query language to create database structures, and store, retrieve and manipulate data in a relational database.
To demonstrate competency in this unit the person will require access to:
Client requirements
Functionality and scope requirements
Access requirements and policy
Security policy
Naming standards
Context of and specific resources for assessment
SQL database functions are in place for most organisations and have become integral to internet-based data provision and data retrieval.
Any assessment of this unit of competency will usually include observation of real or simulated SQL code development and processes data engineering.
The breadth, depth and complexity of knowledge and skills in this competency would cover a broad range of varied activities or application in a wider variety of contexts most of which are complex and non-routine. Leadership and guidance would be involved when organising activities of self and others as well as contributing to technical solutions of a non-routine or contingency nature.
Assessment must ensure:
Performance of a broad range of skilled applications including the requirement to evaluate and analyse current practices, develop new criteria and procedures for performing current practices and provision of some leadership and guidance to others in the application and planning of the skills would be characteristic.
Applications may involve responsibility for, and limited organisation of, others.
Applications involve responsibility for SQL code structures and manipulation of data.
Method of assessment
The purpose of this unit is to define the standard of performance to be achieved in the workplace. In undertaking training and assessment activities related to this unit, consideration should be given to the implementation of appropriate diversity and accessibility practices in order to accommodate people who may have special needs. Additional guidance on these and related matters is provided in ICA05 Section 1.
Competency in this unit should be assessed using summative assessment to ensure consistency of performance in a range of contexts. This unit can be assessed either in the workplace or in a simulated environment. However, simulated activities must closely reflect the workplace to enable full demonstration of competency.
Assessment will usually include observation of real or simulated work processes and procedures and/or performance in a project context as well as questioning on underpinning knowledge and skills. The questioning of team members, supervisors, subordinates, peers and clients where appropriate may provide valuable input to the assessment process. The interdependence of units for assessment purposes may vary with the particular project or scenario.
Guidance information for assessment
Holistic assessment with other units relevant to the industry sector, workplace and job role is recommended, for example:
An individual demonstrating this competency would be able to:
Demonstrate understanding of a broad knowledge base incorporating some theoretical concepts
Apply solutions to a defined range of unpredictable problems
Identify and apply skill and knowledge areas to a wide variety of contexts, with depth in some areas
Identify, analyse and evaluate information from a variety of sources
Take responsibility for own outputs in relation to specified quality standards
Take limited responsibility for the quantity and quality of the output of others
Demonstrate understanding of broad database structures incorporating some theoretical concepts
Manipulate data and provide solutions to a defined range of unpredictable problems
Take limited responsibility for the quantity and quality of database data
Maintain knowledge of industry products and services

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
Analysis skills to determine data objects required, data structures and business requirements
Data modelling skills, particularly during the design and development phases
Report queries and view development using analytical and evaluation skills
Required knowledge
Broad knowledge of data modelling structures
Data analysis, particularly in determining data types, data structures and to query and report design
Run time facilities in relation to implementing live database
DBMS fundamentals
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.
Comparison operators may include:
equal to
not equal to
greater than
less than
greater than or equal to
less than or equal to
Booleanoperators may include the use of:
AND
OR
NOT

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.
