Historical and real-time data access is leveraged to provide unified data access for interacting with manufacturing process entities such as, for example, process overview displays, charting systems, reporting systems, logging systems, and/or recipe systems and the like. The unified data, for example, allows for playback of historical process overviews for a user selected period of time. In one instance, a “VCR like” user interface can be employed to allow ‘rewinding’ and ‘replaying’ of a historical process overview. This facilitates in proper monitoring and/or troubleshooting of manufacturing processes. The unified availability of past and current data also enables reporting systems to provide “living” reports that automatically update with real-time data. This can allow for efficient comparison of current data with historical data for a given manufacturing process.
