Object-oriented design needs to be used whenever it makes sense to do so. Structured design is a choice that can be used when the situation calls for it. what might be making this happen, etc.
Practice Programming Planning Problems using Object Oriented Design– Outline the classes and relationships and describe the programming process for an "automatic meeting scheduler using inputs from a calendar database." Use a simplified version of Unified Modeling Language class diagram. You are not writing the code for this, just the design and the algorithm.
Define the term " procedural cohesion " .

- Benefits of object-oriented analysis and design include its applicability in a variety of settings, including system analysis and design. There are several advantages to using an object-oriented approach, and this is one of them.arrow_forwardObject Oriented Programming (also known as Functional Decomposition) is great for small programs and tasks. It does not scale well as your software system grows because it centers around a single entity that does everything. This makes it hard to easily change your code without requiring multiple changes elsewhere. True/Falsearrow_forwardObject-oriented design should be utilized in all appropriate contexts.
