Service Component Architecture messages are in the form of class expressions. Each class expression is unique to the services and references of a component. Studio provides links from each component to create and edit these class expressions utilizing the same form as creating and editing queries in Actuality.
Components may provide services and/or provide references. Component services are referenced by sending a request message to the service and receiving back a response message. Components may also reference other component services by sending a message to a service of the other component.
