Week 1
"Blah blah blah" said User:Warwick Irwin. Nobody else got to say much. Some wiki pages were mentioned, including:
A big pile of books was waved threateningly at the students.
Everybody was asked to set up an account using their Real name.
Suddenly, it was Wednesday and everything changed. The Video rental system design example appeared, and students huddled into groups to scribble unintelligible marks on scraps of paper. Some of these scribbles were copied to the whiteboard, where they remained unintelligible. Several incantations were uttered:
- Separation of concerns
- Many to many association idiom
- Type and instance idiom (Couldn't think of a better name.)
- Beware type switches
- Switch statements smell
- Avoid redundant data
Learning happened, it seems.
A brave student (or students) should now update the Video rental system page with a record of the design(s) that emerged, & what we observed about it. Have courage.
