AF 2 empowers users to move from a tag-centric view of their PI Server to asset-centric view of their PI Infrastructure. Before AF 2, contextual information was stored in PI Module Database (MDB). There are many applications leveraging the PI MDB today. It is very important for OSIsoft to protect your investment in PI MDB while allowing you to move forward with the latest technology and products from OSIsoft. To achieve this goal, and as part as a PI Server upgrade, the data stored in PI MDB will be migrated to an AF Database. A new PI Subsystem will allow existing PI MDB based applications to integrate with the AF Database. This talk will help you understand and see in action the general concepts of this integration.
