Contract

Contract

Contract is an agreement covering part of the collective behavior of roles. An artifact that serves to capture essential computational viewpoint semantics (or references to them) for management and reuse. Contracts bind together instances of the different services and applications using behavior patterns to fulfill particular business needs. They incorporate the integration semantics that brings disparate systems together. A specified agreement to some behavior common to a configuration of objects, that tells the environment what to expect. [RM-ODP].
