1. A data management system, comprising: processing resources including at least one processor and a memory coupled thereto; and a non-transitory computer readable storage medium; wherein the processing resources are configured to control the data management system to at least: enable a user to define a plurality of different logical containers over time, each logical container being backed by the non-transitory computer readable storage medium; receive sensitive information from the user; retrieve sensitive information from external data sources where authorized by the user, store an electronic representation of the received and retrieved sensitive information to the non-transitory computer readable storage medium; associate the received and retrieved sensitive information with one or more logical containers, the one or more logical containers being hierarchically arrangeable, and the received and retrieved sensitive information being hierarchically arrangeable within the one or more hierarchically arrangeable logical containers, a plurality of different logical levels being defined to reflect both hierarchies of the received and retrieved sensitive information and hierarchies of the one or more logical containers; store, for each logical container, a set of rules identifying one or more other parties that have access to the received and retrieved sensitive information associated with the respective logical container, and conditions under which those one or more parties are granted access to the received and retrieved sensitive information associated with the respective logical container; grant electronic access to a given logical container, and the received and retrieved sensitive information associated therewith, to a given party, external to the data management system, conditioned on the set of rules associated with the given logical container, wherein the granting of electronic access enables the given party to analyze the given logical container, and the received and retrieved sensitive information associated therewith, using a plurality of configurable, hierarchically-arrangeable rules administered by the data management system; record data representative of directly-authorized and indirectly-authorized accessions of logical containers and/or the received and retrieved sensitive information associated therewith; and responsive to a user request for a given logical container, present to the user an indication of the party or parties that has or have accessed the given logical container associated with the user request, and a further indication of what data in the given logical container associated with the user request has been accessed, wherein each said logical container is reusable over time by different parties based at least in part on corresponding updates to the at least one set of rules; wherein each of (a) the received and retrieved sensitive information and (b) content of each said logical container, is updatable over time; wherein the processing resources are further configured to control the data management system to at least transmit a signal to a computing platform of another party to cause an alteration to a multi-step process executed in connection with the computing platform of the another party, the signal being transmittable at any one or more of a plurality of different steps in the multi-step process, including steps where processing responsibility resides with the user and steps where processing responsibility does not reside with the user; and wherein the analyzing of the given logical container, and the received and retrieved sensitive information associated therewith, is at least a part of the multi-step process.
