Within entity-based data store 524 is retained data in a non-relational database format. Thus, the data within entity-based data store 524 may be retained in a structure other than tables. Such structure may be appropriate for large and complex data sets. In some examples, entity-based data store 524 (or any other data store) may be a unified system, which may include: a document-centric, schema-agnostic, structure-aware, clustered, transactional, secure, database server with built-in search and a full suite of application services. An example of such a unified system may be Marklogic. Entity-based data store 524 can support data aggregation, data organization, data indexing, data tagging and mapping to semantic standards, concept matching, concept extraction, machine learning algorithms, concept discovery, concept mining, and transformation of personal record information. In some examples, entity-based data store 524 includes data pertaining to decision making (similar to general data store 520) as discussed that is organized and accessed in a different manner. For example, the data within entity-based data store 524 may be optimized for providing and receiving information over one or more information exchanges. In some examples, entity-based data store 524 includes a subset of the information that is included in operational data store 522.
