  DESIGN OF OBEJECT ORIENTED APPLICATIONS (DOA) DOOA:  Creating a blueprint or plan for the behaviour and structure of the software system is a necessary step in the design of an object-oriented application.  This procedure makes ensuring the application is scalable, modular, and maintainable. To develop an object-oriented programme, remember to take the following important phases and factors into account: 1. Identify needs:  Start with comprehending the objectives and needs of the application.  To do this, one must collect both functional and non-functional requirements, comprehend the issue domain, and pinpoint user requirements.  The design process is aided by the objectives being well defined. 2. Determine the major Objects and Classes:  Decide which classes and objects will be the major components of the programme.  Classes specify the guidelines for producing objects, while objects reflect actual things in the real world.  Determine these things' characteristics (info
