What is a Framework?

• A set of reusable classes and interfaces that cooperate to solve a software problem
• Provides abstractions of particular concepts, e.g. M-V-C
• Defines how abstractions work together to solve a problem
• Provides generic behavior that many different types of applications can use
• A framework is not a library:
  • Library: functions or routines that your application can invoke
  • Framework: code with extension points (hooks and slots) where you can provide functions
