Overview of assessment
Critical aspects for assessment and evidence required to demonstrate competency in this unit
Evidence of the ability to:
undertake activities from proposal to implementation stage for a data warehouse model that reflects current and future business requirements and the business knowledge management strategy.
Context of and specific resources for assessment
Assessment must ensure access to:
data in a DBMS
data-warehousing tool
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:
written report outlining:
cost-benefit analysis of a data warehouse implementation for a defined organisation
user guide for usage of an implemented data warehouse
technical documentation for an implementation of a data warehouse
questioning to determine knowledge of relationship between databases and data warehouses
project to implement a data warehouse.
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.
