Introduction

Why OO

  • Modern systems are large and complex - lots of interconnected components, distributed and heterogeneous.
  • OO is particularly useful to build such systems.
  • Remember OO is not always the best approach, but is useful in the right setting.

When to use OO

  • For the systems where the user is in control e.g. decision support systems, CRM's, enterprise systems. OO makes it easier to model such systems.
  • Systems where long term extensibility is important. Again OO's concepts make it easier to incorporate extensibility.

What is OO Development

  • Quite simply, the use of classes and objects in developing software and systems.
  • OO Development implies using classes and objects throughout the construction process - requirements analysis, design, coding and testing.
