Referring next to FIG. 5, a diagram 500 is shown that depicts a portion of architecture stack 300 according to an embodiment of the invention. In particular, diagram 500 includes active unified data layer 308 and a portion of access management layer 310. Active unified data layer 308, as illustrated in diagram 500, includes an interoperability engine 502 (e.g., interoperability engine 220), a transaction management collection engine 504, a data store integrity engine 506, and a data store 508 (e.g., data store 226). Generally, interoperability engine 502 receives data from elements within aggregation layer 304 (e.g., from aggregation engine 420) and performs one or more operations with respect to the data. Interoperability engine 502 also facilitates storage of at least a portion of the processed information in data store 508.
