What are the advantages and disadvantages of object oriented programming?

What are the benefits of object model?

What is the difference between an object and a class in the object oriented data model?

What is the difference between an object and a class in the object-oriented data model (OODM)? An object is an instance of a specific class. … A class is a collection of similar objects with shared structure (attributes) and behavior (methods.) Therefore, a class resembles an entity set.

Where is object oriented database used?

Consider an object database when you have a business need for high performance on complex data. Generally, an object database is a good choice when you have all three factors: business need, high performance, and complex data.
