Abstract: A data organization scheme for business applications is disclosed wherein a shared core set of constituent data is centrally maintained for an individual or organization that takes on multiple roles. Additional data that is specific to the roles is separately maintained. The constituent data organization subsystem provides a means to track organizations and individuals as unique entities, as well as to manage the diffuse and context-dependent ways in which they represent themselves within a system. Also disclosed are specific security, data analysis and other features enabled through an implementation of the proposed constituent data organization scheme.
