The basis of object-oriented systems development is primarily centered around the use of the object as the unit of design. This approach means that the fundamental building blocks of the system are objects, which encapsulate both data and behavior related to that data. Objects represent real-world entities and are designed to model how those entities interact with one another through their defined behaviors (methods).

By placing emphasis on objects, this methodology fosters code reusability and modularity. It allows developers to create more complex systems by composing them from simpler, self-contained units. Additionally, inheritance, polymorphism, and encapsulation are key concepts in object-oriented design that enhance flexibility, leading to easier maintenance and expansion of applications over time.

In contrast, focusing solely on data structures does not capture the behavior aspects necessary for designing a responsive and adaptable system. Database management is crucial in information systems but is not the foundational principle of object-oriented design itself. Similarly, functional programming principles are distinct from object-oriented approaches, as they focus on the use of functions as the primary building blocks rather than objects.
