Oracle Utilities Network Management System shares a common model between the OMS and DMS modules. If a customer decides to implement DMS functionality they will need to layer engineering attributes (for example, impedances, voltage, ratings, and so on.) onto the existing OMS connectivity model such that a power flow analysis can be conducted. If desired the engineering attributes can be pulled from 3rd party data such as GIS, planning system, and so on. Since the model is common between the OMS and DMS modules there are no requirements to implement a synchronization process between these two systems.

Module specific data requirements are discussed in later sections.
