Software design

Software design

1. Strategic programming

   • Produce a great design
   • Simplify future dev
   • Minimize complexity
   • Take extra time

2. Tactical programming

   • Get bug/feature ASAP
   • Use shortcuts
   • Bad design, High complexity

3. Code isn't enough

4. Classes

   • Should be deep
     • Real problem its abstraction
   • Large functionality underneath

5. Define errors out of existence

   • Exeption = Huge complexity
   • Minimize # places where exceptions must be handled
   • Try to reduce numbers of exceptions
     • Define semantics

6. Common problems

   • Pressure to get first
   • Fully tactical programming

7. Recomendation

   • Careful design
   • Good documentation
     • Find something to improve
