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 identify technical considerations affecting the physical design of a database and the ability to build a database that meets the client's database performance requirements.
The final database will meet specified business rules, agreed budget and timeframe. The database will perform efficiently in the runtime environment (the environment required to operate the designed solution, not the development environment).
Reports must meet the specific output requirements and be presented in a logical and accessible manner.

To demonstrate competency in this unit the person will require access to:
Client requirements
Project deliverables
Acceptance criteria
Current IT blueprint
Security system plan
Technical specifications
Business analysis process outcomes

Assessment of this unit of competency will include a review of developed documents detailing:
Database directories
Calculation of space requirements for tables
Additional space requirements
Design of node groups
Context of and specific resources for assessment
Technical documentation defining architecture, platform and operating system specifications; database supplier technical specifications and manuals; data samples; database package.

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.
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:
ICAA4041C Determine and confirm client business expectations and needs
ICAB4059B Develop detailed technical design
ICAB4061B Monitor physical database implementation
ICAD4043B Develop and present a feasibility report
ICAS4125B Monitor and administer a database

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
