List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.
ELEMENT | PERFORMANCE CRITERIA |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Determine the requirements of developing queries | 1.1 Recognise various query-related terminologies 1.2 Identify the type of data source for a chosen query language 1.3 Identify and use the necessary tools, and environment, in building queries |
2. Write queries to retrieve and sort values | 2.1 Use an expression to retrieve values from a single unit 2.2 Use an expression to combine values from more than one unit 2.3 Use an expression to sort values into a certain order |
3. Write queries to selectively retrieve values | 3.1 Use an expression to filter a sequence, based on a predicate or a condition 3.2 Use an expression to filter the subset of a sequence, based on a predicate or a condition 3.3 Use an expression to extract a specific value by position |
4. Perform a calculation in queries | 4.1 Use an expression to perform a calculation on numeric values 4.2 Use an expression to perform an operation on text values 4.3 Use an expression to perform an operation on date and time values |
Evidence of the ability to:
select and use tools in developing, storing, and executing queries to extract the appropriate data required for ad hoc reports, or to support developers
incorporate calculations using control statements, operators and functions.
Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
To complete the unit requirements safely and effectively, the individual must:
outline the information gathering methods
outline the data analysis techniques
define data mining
outline the characteristics of the data source
explain the features of the information system
explain typical systems and procedures.
Gather evidence to demonstrate consistent performance in conditions that are safe and replicate the workplace. Noise levels, production flow, interruptions and time variances must be typical of those experienced in the programming and software development industry, and include access to:
a data source
resources in the chosen query language
documentation regarding client and functionality requirements
resources to aid calculation.
Assessors must satisfy NVR/AQTF assessor requirements.
