An operational data hub (ODH) is a pattern in data architecture that provides a central location and a standard protocol for operational systems to communicate about and share data among themselves. Operational systems post messages about data events (add, change, delete) and subscribe to messages of interest posted by other applications. The hub works to share data among applications without the clutter and chaos of point-to-point data feeds.
