Application
This unit describes the skills and knowledge required to produce server-side scripts for dynamic web pages, using a range of relevant features from different but appropriate languages.
It applies to individuals working as web designers who apply a wide range of knowledge and skills across different information and communications technology (ICT) environments to support small to medium enterprises (SMEs) that require broader, rather than more specialised, ICT support.
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. Analyse the requirements for web documents requiring server-side dynamic interaction | 1.1 Determine the necessary dynamic functionality of the web document 1.2 Determine the appropriate language, to achieve that functionality 1.3 Determine web document requirements |
2. Design server-side scripts | 2.1 Design the web document and server-side code, to interact with an external data source 2.2 Design the web document and server-side code, to allow an administrator to insert, update, and delete entries to the external data source 2.3 Implement security features in the web document |
3. Produce the web documents | 3.1 Write the extensible hypertext markup language (XHTML), considering accessibility 3.2 Write server-side scripts to current XHTML standards |
4. Test the scripts and debug | 4.1 Test the web document against required the functionality and reiterate until correct 4.2 Complete the documentation and submit it to the appropriate person for their approval |
5. Set up security | 5.1 Determine the necessary permissions to prevent error messages displaying to the public 5.2 Configure server software to minimise potential database attacks |
Evidence of Performance
Evidence of the ability to:
create dynamic web pages according to all job requirements, using server-side scripting to retrieve information from a web-hosted database
create scripts for:
the quick upload of data to web-hosted databases
inserting, updating, and deleting data from a web server database
encoding passwords
uploading and retrieving images
managing sessions, and creating a secure login.
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:
explain server-side technologies, and the relevant web scripting languages
discuss server-side web analysis and design parameters
summarise and apply, programming control structures and object-oriented programming
outline web-programming concepts including:
the hypertext transfer protocol (HTTP)
stateless programming
session management
authentication and web security.
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 website technologies field of work, and include access to the:
client requirements
functionality and scope requirements
security policy
database server
internet and server
software development environment
web browsers.
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 |
Reading | 1.1, 1.3 | Identifies, analyses and evaluates workplace instructions and technical documentation, to determine all business requirements |
Writing | 2.2, 2.3, 3.1, 3.2, 4.2 | Develops clear and well-organised material for a specific audience, using precise language to convey explicit information requirements and recommendations |
Oral Communication | 1.1, 1.3 | Clearly articulates requirements using the language appropriate to the audience, and participates in a verbal exchange of ideas/solutions |
Navigate the world of work | 3.2 | Identifies and complies with the current standards |
Interact with others | 4.2 | Uses a range of strategies to establish a sense of connection, and to build rapport, with clients and co-workers |
Get the work done | 1.2, 2.1, 2.2, 2.3, 4.1, 5.1, 5.2 | Takes responsibility for planning, sequencing and prioritising tasks and own workload, for efficiency and effective outcomes Makes routine decisions and implements standard procedures for routine tasks, using formal decision- making processes for more complex and non-routine situations Uses familiar digital technologies and systems to access information, search and enter, data and code, present information and communicate with others, cognisant of data security and safety |
