The final tier of integration offers the ability to create entirely new applications (or applets) that may or may not have a data store of their own, and that utilize the high-quality, high-integrity data stores that have been integrated together in the previous tiers.
For example, a SAP NetWeaver portal can host “Web parts” (iViews) from Hexagon, Meridium and SAP simultaneously – all communicating with each other as part of a “role-based” application. In this example, a reliability engineer is browsing engineering data, maintenance data and failure data simultaneously, querying each application as if they were one, and then executing a new task which is not part of the three integrated systems, but of the new “composite applet.”
