Study Notes

Operation Contracts

Operation contracts define system behavior in terms of state changes to domain objects.
Contracts describe detailed system behavior in terms of state changes to objects in the Domain Model, after a system operation has executed.
An operation contract is defined mainly in terms of two key components:
- Pre-conditions
- Post-conditions
