Advantages of ADT

Some advantages of ADT over the conventional data structures are

  • ADT is reusable, robust, and is based on principles of Object Oriented Programming (OOP) and Software Engineering (SE)
  • An ADT can be re-used at several places and it reduces coding efforts
  • Encapsulation ensures that data cannot be corrupted
  • Working of various integrated operation cannot be tampered with by the application program
  • ADT ensures a robust data structure
ADT approach is based on the SE concepts of coupling and cohesion
Coupling property determines
  • How strongly two separate parts of programs are linked together
  • Extend to which changes made in one part impacts the other parts of a software module
Well designed software has a minimum coupling. An ADT promotes weak coupling.
Cohesion determines how well-integrated are components of software. An ADT inherently promotes maximum cohesion.
