Evidence Required
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: install and configure database software manage database files, integrity, users and security create backup and restore databases monitor database performance. |
Context of and specific resources for assessment | Assessment must ensure access to: database-management system software database instance tools in administering database specific requirements, including client and functionality requirements policy and naming standard 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: direct observation of candidate performing: the installation, configuration and troubleshooting of a database management system software database tuning for performance using appropriate techniques and tools database backup creation and restore using the backup file data-management tasks, such as importing and exporting data, and instance creation database security tasks, such as creating users, and assigning roles and permissions to database users verbal or written questioning to determine candidate’s knowledge of database tuning and database security review of candidate’s database documentation. |
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. |
