OCL 2.0

OCL 2.0 (Object Constraint Language 2.0) is a formal language used to specify rules and constraints for software models, particularly in designing complex systems. It allows developers to define precise conditions and relationships among objects within a model, ensuring consistency and correctness. Think of it as a way to write clear, machine-readable rules that validate how parts of a system should behave and relate to each other, making the design more accurate and easier to verify. OCL 2.0 enhances this by offering more expressive power and better integration with modeling tools.
