28. University of Vienna, Institute of Distributed and Multimedia Systems Business State Centric nBusiness Collaborations are about managing a shared view on Business States. nAligning Business States between business partners requires exchange of Business Information. nBusiness Information is limited to the information required to change the state of one or more Business Entities affected by the exchange. nBusiness Documents also have the potential to change the state of a business entity. However, business documents do not concentrate on what is needed to change the state, and thus, include a lot of unnecessary data. nEach element included in a business document exchange is a source for incompatibility. nLimit the Business Information exchange to an absolut minimum, i.e. the information required to change the State of a Business Entity.
