software design & development

1. development methodologies

   • agile
   • traditional/waterfall

2. software development process

3. development methodologies

   • agile
     • changing design requirements is allowed throughout development
     • constant co-operation between client and developer.
     • team reflection/evaluation
   • traditional
     • developer works independently
     • developer sends only a few things for the client to check
     • client is less involved

4. software development process

   • analysis
     • requirements set
   • design
     • design must meet all the requirements set for it
   • implementaion
   • testing
   • documentation
   • evaluation
     • look back on project and see what could be done better and what was done well
   • maintenance
     • update, fix, debug code to allow for efficiency

5. parameter passing

   • procedure
   • subroutines
     • increase maintainability of the code
     • easy to identify for debugging, testing and editing
   • subprograms
   • modularity
     • using two subprograms in software is call modularity

6. reading and writing files

   • csv file name only
   • open
     • read/write
       • close

7. parallel arrays

   • two lists in one file
     • (, )split line
