In some embodiments, the instant invention provides for a computer-implemented method that includes steps of: receiving data feeds associated with healthcare-related entities, where a data schema of each data feed is unknown prior to the receipt; automatically determining, in real-time, for each entity, at least: a first type data fragment identifying an identifier associated with the entity and ii) second type data fragments containing items of information about the entity; automatically storing the entity information across distributed non-relational computer databases, by: creating, each time, records, where each record includes a row with columns, where the row is associated with the first identifier and where each column of the row has: 1) a name composed of a hierarchical path to a content of each column and 2) the item of information of the second type data fragment; and determining a verified record of the entity at a particular time.
