Abstraction - 2

• Three basic abstraction mechanisms:

  • procedural abstraction
    • specification describes input/output
    • implementation describes algorithm
    • types: structural
  • data abstraction
    • specification describes attributes, values, properties, operations
    • implementation describes representation and implementation
    • types: compound data structure, abstract data type
  • control abstraction
    • specification describes desired effect
    • implementation describes mechanism
    • types: selection, repetition
