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.
Diagnostic tool may include: | server software or may be inbuilt to the server software software applications external to the database server. |
Database may include: | commercial off-the-shelf (COTS) database packages object-relational databases proprietary databases relational databases. |
Performance may include: | archiving old records compacting database files creating indexes improvements to response time latch contention preventing events causing waits record or table locking repairing the database simultaneous access splitting database files. |
Architecture may include: | configuration: large memory model requests per second small memory model database software: DB2 Informix Ingres Microsoft SQL (MS SQL) server Mini SQL (mSQL) MySQL Oracle Sybase operating system: Linux Mac multi-user ability Novell NetWare 5 or above Windows 2000 or above. |

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
