System Interface

A System Interface is a boundary component that enables system interaction through defined protocols.

• AKA: Interface, System Boundary, Component Interface, System Interaction Point, System Connection Interface.
• Context:
  • It can typically define Interface Protocols through specification documents.
  • It can typically enable System Component Communication via message passing mechanisms.
  • It can typically enforce Interface Contracts through validation rules.
  • It can often provide Interface Capabilitys through exposed functions.
  • It can often implement Interface Security Mechanisms via access control policys.
  • It can often maintain Interface Version Management through versioning strategys.
  • It can range from being a Simple System Interface to being a Complex System Interface, depending on its functionality scope.
  • It can range from being a Physical System Interface to being a Logical System Interface, depending on its implementation type.
  • It can range from being a Synchronous System Interface to being an Asynchronous System Interface, depending on its timing model.
  • It can range from being a Static System Interface to being a Dynamic System Interface, depending on its binding time.
  • It can integrate with Interface Monitoring Systems for performance tracking.
  • It can integrate with Interface Testing Frameworks for validation checks.
