OOPDA Lab 03B UML SEQUENCE DIAGRAM [using markup]Problem: Develop a Sequence Diagram (“SD”) for a lamp with a pushbutton that will
toggle off and on as user pushes button.
Use at least one ALT or OPT box in your SD. Preferably, more than one, possibly nested!
[Suggestion, consider scenario where user presses button and lamp doesn’t turn on!]
• Behavior to diagram: Imagine a LAMP that has a pushbutton on its base,
which will toggle the lamp ON or OFF.
1) Diagram a typical interaction(s) with a USER, then..
2) Consider one atypical situation and diagram it using
an alternative or an optional grouping
[consider some unusual scenarios,
like pushbutton doesn’t turn on lamp – what to do?]
3) Remember that you can use nested controls; for example, an alt box inside another alt box!
This lab should introduce SD as an analysis tool for a simple(?) problem, plus use of a diagramming app to create SD’s.
There will be about five more SD’s assigned throughout the course, so becoming a little familiar with
sequencediagram.org and its features now will be helpful. Experiment!!
Procedure using seqencediagram.org:
a) Open in browser: https://sequencediagram.org/
b)
– brings up Alice,Bob example with markup at left
c)
[Can click “Help” on menu at upper right then “Instructions” for a short reference manual]
d)
Can edit markup in left panel as needed…
◼ Can erase sample markup, start with your line 1), or edit
◼ continue your markup
◼ Ctrl-z erases last edit
e)[can add controls using mouse and selected objects]
◼
◼
◼
◼
Move mouse pointer and Right-click on diagram to add controls
automatically changes markup.
— select “fragment” for loop, opt, alt or par
— can also add box, note etc.
— click on timeline then “activate” to add active segment to timeline
f) Use “Export” icon at left to save as png
◼ I chose “render” then right-clicked to “save as”. There are several other ways to do this.
g) Drag mouse over your markup code, and paste into a Word doc or a text txt file
2) Deliverable: Submit png of your diagram, plus Word doc with your markup code
