Requirements
Requirements state precisely what the application must do, for whom, and what counts as finished.

The big idea
The Class 9 capstone is a database-backed application taken from written requirements through implementation to something running somewhere other than the student’s own laptop.
Why it matters
Deployment is the step most school projects skip, and the one that makes a project feel real to the student who built it.
Unpacked
What you will actually learn
Three core ideas, each taught with worked examples and then practised until it feels obvious.
Implementation
Implementation proceeds feature by feature, tested as it goes, with the application working at the end of each session.
Deployment and demo
Deployment and demo mean getting it running for someone else and presenting it under questioning.
Did you know?
“It works on my machine” is the oldest joke in software. Deployment exists because that sentence is never enough.
Common mix-up
“Deployment is the last step.” Deploying early and often catches environment problems while they are still small.
Session by session
Your 8-session journey
Sessions 65–72 of the 72-session year, at two one-hour sessions per week.
- 1
Warm-up and big picture
Where this module fits, what you will build, and a hands-on starter that gets everyone curious about requirements.
- 2
Requirements
Guided teaching on requirements, worked through together with the teacher.
- 3
Requirements — practice lab
Independent practice, small challenges and one deliberate mistake to diagnose.
- 4
Implementation
Guided teaching on implementation, building directly on the previous two sessions.
- 5
Implementation — practice lab
Applied tasks that combine requirements and implementation in one piece of work.
- 6
Deployment and demo
Deployment and demo introduced and practised, completing the toolkit needed for the project.
- 7
Project build
Guided build session for the module project: Database-backed Python application.
- 8
Test, present and reflect
Finish, test against the checklist, present the work and explain the decisions behind it.
Project lab
Database-backed Python application
Every module ends with something the student built themselves and can demonstrate. This is the piece that goes into their portfolio and gets explained out loud at the end of session 72.
Try this at home
Deploy your app, then hand the link to someone who has never seen it and give no instructions at all. Watch what happens.
It is finished when
- It works from start to finish without breaking
- You can explain every part of it in your own words
- You tested it and improved at least one thing afterwards
- Someone else used or understood it without your help
By the end of this module
Students finishing Module 9 can:
- Explain and use requirements without prompting
- Explain and use implementation without prompting
- Explain and use deployment and demo without prompting
- Build and finish database-backed python application
- Test your own work and correct what you find
- Talk an adult through what you made and why
Word bank
The vocabulary introduced here, in plain language:
- deployment
- Making software available where others can run it.
- environment
- The system and settings a program runs under.
- demo
- A live demonstration of working software.
