Description
This unit describes the performance outcomes, skills and knowledge required to produce structured query language (SQL) statements to work with server-side scripts enabling web designers to interact with web server databases.
Notes
Elements and Performance Criteria
1. Identify SQL requirements from the specification documentation
  • 1.1 Determine information to be used from database
  • 1.2 Identify tables that hold this information
  • 1.3 Identify primary keys in these tables
  • 1.4 Identify relationships between these tables, including foreign keys
2. Create a relational database
  • 2.1 Create tables in a database using SQL statements
  • 2.2 Identify primary and foreign keys for database table
  • 2.3 Manipulate data in a database using SQL statements
  • 2.4 Query the database using SQL statements
  • 2.5 Write SQL statements to retrieve information from database
3. Test SQL results
  • 3.1 Construct test data to test SQL statements
  • 3.2 Construct expected results to verify SQL statements
  • 3.3 Verify result of the constructed SQL statements against expected results
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:
Access
Informix
Microsoft Structured Query Language (MS SQL)
MySQL
Oracle
Postgre
Sybase.
SQL statements may include:
aggregate functions
conditions and Boolean operators
conditional operators
mathematical operators
table joins.
Manipulating data may include:
creating tables and rows
deleting tables and rows
adding and altering data
retrieving data.
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 use SQL to:
create databases and tables
query one or more tables to provide required data
add, modify and delete records from tables
drop databases and tables.
Context of and specific resources for assessment
Assessment must ensure access to:
development environment
server access
database server
appropriate learning and assessment support when required.
Where applicable, physical resources should include equipment modified 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 SQL statements and procedures
review of project-based SQL application prepared by candidate.
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.
