contract-to-logic coupling

The extent to which a service contract is dependent on the underlying service logic is referred to as contract-to-logic coupling.

This is considered a negative type of service coupling because service consumer programs that bind to the service contract end up also inadvertently forming dependencies on the underlying service logic.

One of the reasons service-oriented design processes advocate a "contract first" approach to service design is to avoid contract-to-logic coupling, which commonly emerges when service contracts are auto-generated by development tools.
