Can we get a definition of "coupling" and "cohesion" for object-oriented analysis and design?

Discuss the principles of SOLID in object-oriented programming. Explain each principle (Single Responsibility, Open/Closed, Liskov Substitution, Interface Segregation, Dependency Inversion) and how they promote good software design.

Does Object Orientation require a definition of its own? software engineering with an emphasis on objects

How can you ensure that method overriding is done correctly to maintain the Liskov Substitution Principle in object-oriented design?

Object-oriented design should be employed whenever it makes sense to do so, which is pretty much everything. When the conditions call for it, the use of structured design is an alternative that may be considered appropriate. what are some of the possible explanations for this, etc.
