Program Description Answer

Approach of analyzing system using objects is known as object-oriented analysis.

Object-oriented analysis is based on objects and their interaction with the system. Objects can be any identifying entity such as a person, machine, place or any transaction which interacts as a group.

Object−oriented analysis is an approach to analyze the system through its group of objects and their functions to create an object model. Object model is a system based on object and its interactions in the form of functions.

  • Focus is on object or data and not on procedures or functions.
  • Effective in utilizing concepts of data encapsulation and data hiding.
  • It develops modules which can be easily reused and can be upgraded from smaller modules to large modules.
