Introduction to Programming

Software Engineering

• The Software Life Cycle
  • Problem Definition and Specification
    • Prototyping
    • Requirements
  • Design
  • Development
  • Testing
  • Deployment
  • Maintenance
    The system should be: correct, rugged, efficient, modifiable, portable

• Programming in the Small
  • Usually done by one person or a small group
  • Code should be clean and easy to modify
• Programming in the Large
  • Work should be partitioned into modules
  • Interactions should be precisely specified
  • Careful planning, project management, and documentation
  • Architecture should be designed to minimize changes
  DeRemer and Kron:

  "... structuring a large collection of modules to form a `system' is an essentially distinct and different intellectual activity from that of constructing the individual modules."
