The role of open systems in the enterprise Supporting open distributed computing while meeting local requirements

Copyright © 2001, Data Access Technologies, Inc. The Enterprise “The Enterprise” The “open domain” zIndependent domains collaborating via open standards zNo assumption of “the same thing” on both sides! zAppropriate inside and outside the enterprise (EI & B2B) zRequires business (process collaboration and information) and technical (middleware) standards zThe open domain needs a point of ownership in the enterprise Enterprise boundaries are not static!

Drilling down – inside a role zThe open domain should make no assumptions about the “inside” of a role. zInside one role you frequently find more collaborating “parts” of the enterprise - the same model may be used zUntil you get to system inside a managed domain yShared resources (DBMS) yCommon Management yFrequently a legacy system Inner Role Legacy Inner Role Inner Role Domain Cust

Copyright © 2001, Data Access Technologies, Inc. Collaborative Business Semantics zDefined: The processes, information and contracts of interaction between collaborators within a community zCollaborative business semantics are a valuable long- term asset zCaptures information and process zRequires ownership and support in the open domain zDo not put this valuable asset in a (transient - one size fits all) technology specific form yUse technology independent models (MDA) yMap to the technology of the day (E.G.
