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: build and implement a well-structured database that represents the client's business reality provides the user with a productive business tool conforms to the client’s standards and structures. |
Context of and specific resources for assessment | Assessment must ensure access to: business requirements and strategy database design documentation database software programming language 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: verbal or written questioning to assess candidate’s knowledge of functions and features of databases and the process of developing a prototype evaluation of database review of: database documentation, including security controls test data used to test database functionality. |
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. |
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.
Database may include: | DB2 Informix Ingres Microsoft SQL (MS SQL) server Mini SQL (mSQL) MySQL Oracle Postgre Structured Query Language (Postgre SQL) Sybase. |
Documentation may follow: | audit trails International Organization for Standardization (ISO), International Electrotechnical Commission (IEC) and Australian Standards (AS) standards naming standards project management templates report writing principles version control. |
Client may include: | clubs external organisations individuals internal departments internal employees. |
Database management system may include: | distributed or centralised online partitioned geographically thematically distributed. |
Requirements may relate to: | business network people in the organisation system. |
