The Object-Oriented architecture is one of the most important and commonly utilized for developing software. n architecture in which everything (processes, files, I/O operations, etc.) is represented as an object. Objects are data structures in memory that may be manipulated by the total system, i.e. both hardware and software, and they provide a high-level description that allows for a high-level user interface. This architecture promotes various object-oriented concepts like Encapsulation, Inheritance, Polymorphism, Composition, Association, Objects, Classes and much more. The style of creating object-oriented software’s is completely different from functional or procedural style.
A software built by strictly following the object-oriented concepts makes it highly robust, scalable, reusable, maintainable and testable. It also reduces development time and cost. Object-oriented architecture systems can thus be considered as an extension or generalization of capability architecture systems and have the same ability to provide a basis for protection and computer security.
