Elements and Performance Criteria Pre-Content

Elements describe the essential outcomes of a unit of competency.	Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide.

Elements and Performance Criteria

ELEMENT	PERFORMANCE CRITERIA
1. Confirm database design	1.1. Review database design documentation, including data structures, queries, reports and user interface 1.2. Compare database access and security feature design with organisational security plan 1.3. Document inconsistencies in database and security design

Evidence Guide

EVIDENCE GUIDE
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 build and implement a well-structured database that represents the client's business reality and provides the user with a productive business tool. To demonstrate competency in this unit the person will require access to: Database software Database design documentation Business requirements and strategy
Context of and specific resources for assessment	Appropriate database design with relevance to the organisation's objectives can provide rapid access to information, achieve client satisfaction and provides an ability to change to meet new demands on the organisation. 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. An individual performing at this standard will display self-directed application of knowledge and skills, with substantial depth in database design and development where judgement is required in planning and selecting appropriate equipment, services and techniques for self and others.
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, such as: ICAB4136B Use structured query language to create database structures and manipulate 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 Maintain knowledge of industry products and services
