The general intent is that any corporate application (such as an order entry system or billing) requiring the use of customer information can interact through a services layer to the single view in order to obtain de facto information for any particular customer. Should any information within the single view prove to be incorrect, all subscribing applications would have had access to the same incorrect data at the same time. Further, should a service that writes or manipulates data in the single view contain a bug, any element that is touched could be compromised. In this way, data can be viewed as having viral properties. In an SOA environment, the effect can be akin to a pandemic-an enterprise pandemic SOA http://www.soamag.com/contributors/bio-rfishman.asp#When:31.08.09
