Like master/slave ownership, this model avoids update conflicts while at the same time providing a more dynamic ownership model. Workflow ownership allows the right to update replicated data to move from site to site. However, at any one moment, there is only ever one site that may update that particular data set. A typical example of workflow ownership is an order processing system, where the processing of orders follows a series of steps, such as order entry, credit approval, invoicing, shipping, and so on. In a centralized DBMS, applications of this nature access and update the data in one integrated database: each application updates the order data in sequence when, and only when, the state of the order indicates that the previous step has been completed.
