Application
This unit describes the skills and knowledge required to define and produce common gateway interface (CGI) script and install that script on a server.
It applies to individuals working in the network or web development area who are required to use CGI scripting as a common means of interacting with websites, providing security access to directories and databases.
No licensing, legislative or certification requirements apply to this unit at the time of publication.
Elements and Performance Criteria
ELEMENT | PERFORMANCE CRITERIA |
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. |
1. Define specification for CGI script | 1.1 Determine the functionality of the CGI form 1.2 Define the functionality of the CGI script 1.3 Choose appropriate language in which to write the CGI script 1.4 Determine server requirements |
2. Create CGI form and write script | 2.1 Produce a hypertext markup language (HTML) web document that uses the form elements required by the CGI script specification and includes the uniform resource locator (URL) for the CGI script 2.2 Write the CGI script to function as required by the CGI script specification |
3. Test CGI script | 3.1 Configure the server, if required, that will host the CGI script 3.2 Upload the CGI script to the server 3.3 Run the CGI form and assess its output 3.4 Reiterate until the specification for the CGI script is met |
Evidence of Performance
Evidence of the ability to:
review the requirements
produce common gateway interface (CGI) forms and scripts to meet the requirements
upload scripts to a server
test the script and rework until requirements are met.
Note: If a specific volume or frequency is not stated, then evidence must be provided at least once.
Evidence of Knowledge
To complete the unit requirements safely and effectively, the individual must:
identify and describe a scripting language suitable for CGI
describe CGI 1.1/1.2 specifications and their functionality
describe the security issues surrounding CGI
outline common web servers
outline the principles behind copyleft and Free Software Foundation
describe copyright and intellectual property issues relating to programming.
Assessment Conditions
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 network industry, and include access to:
web servers
an e-business website
file transfer protocol (FTP) or file transfer client software
server access.
Assessors must satisfy NVR/AQTF assessor requirements.
Foundation Skills
This section describes language, literacy, numeracy and employment skills incorporated in the performance criteria that are required for competent performance.
Skill | Performance Criteria | Description |
Writing | 1.2, 2.1, 2.2 | Prepares workplace documentation that incorporates an evaluation of technical information and specialised and cohesive language in a format and style appropriate to a specific audience |
Numeracy | 2.1, 3.3, 3.4 | Analyses numerical data to determine functionality of script |
Get the work done | 1.1, 1.3, 1.4, 2.1, 3.1-3.4 | Takes responsibility for planning and organising own workload, identifying ways of sequencing, prioritising and monitoring own work Uses familiar digital systems and tools to access, organise, analyse and display information relevant to role Understands the purposes, specific functions and key features of common digital systems and tools, and operates them effectively to complete routine tasks Makes a range of important decisions in relatively complex situations, taking a range of constraints into account When dealing with complex issues, may use intuition to identify the general problem area, switching to analytical processes to clarify goals |
