9. The apparatus of claim 1 wherein said at least one processing platform is further configured to at least one of replicate the data records, generate one or more snapshots of the data records and replace the data records.

10. The apparatus of claim 1 wherein the one or more of the plurality of data access policies are dynamically generated and analyzed in real-time during active sessions with one or more of the plurality of clients.

11. The apparatus of claim 1 wherein said at least one processing platform is further configured:

to assign a trustworthiness level to one or more of the plurality of data systems; and

to disable access to the one or more of the plurality of data systems in response to a negative change in the trustworthiness level.

12. The apparatus of claim 1 wherein said at least one processing platform is further configured:

to assign a trustworthiness level to one or more of the plurality of data systems; and

to quarantine data records in the one or more of the plurality of data systems produced after assignment of the trustworthiness level.

13. The apparatus of claim 1 wherein said at least one processing platform is further configured:

to determine whether given ones of the data records have been compromised;

to quarantine the given ones of the data records that have been determined to be compromised; and

to recreate the given ones of the data records from a snapshot.

14. The apparatus of claim 1 wherein said at least one processing platform is further configured to validate a trustworthiness of a data collection endpoint of the channel prior to transmission of the one or more of the data records through the channel.

15. A method comprising:

receiving a plurality of requests for data records from a plurality of clients, wherein the data records are in a plurality of data systems of a global namespace, and wherein the plurality of data systems are in a plurality of locations;

determining whether a given client of the plurality of clients is allowed access to one or more of the data records based on one or more of a plurality of data access policies;

retrieving the one or more of the data records from at least one of the plurality of data systems based on a determination that the given client is allowed access to the one or more of the data records;

providing the one or more of the data records to the given client; and

generating a plurality of data descriptors describing one or more characteristics of respective data records, wherein the one or more characteristics comprise one or more schemas for structuring content of one or more of the respective data records and respective versions of the one or more schemas, the one or more schemas defining how the content is organized in the one or more of the respective data records and how relationships in the content are structured;

wherein retrieving the one or more of the data records comprises:

determining a location of the plurality of locations for the one or more of the data records; and

generating a channel to the location through which the one or more of the data records are retrieved;

wherein the method is performed by at least one processing platform comprising at least one processing device comprising a processor coupled to a memory.

16. The method of claim 15 further comprising:

assigning a trustworthiness level to one or more of the plurality of data systems; and

disabling access to the one or more of the plurality of data systems in response to a negative change in the trustworthiness level.

17. The method of claim 15 further comprising:

assigning a trustworthiness level to one or more of the plurality of data systems; and

quarantining data records in the one or more of the plurality of data systems produced after assignment of the trustworthiness level.

18. The method of claim 15 further comprising validating a trustworthiness of a data collection endpoint of the channel prior to transmission of the one or more of the data records through the channel.

19. A computer program product comprising a non-transitory processor-readable storage medium having stored therein program code of one or more software programs, wherein the program code when executed by at least one processing platform causes said at least one processing platform:

to receive a plurality of requests for data records from a plurality of clients, wherein the data records are in a plurality of data systems of a global namespace, and wherein the plurality of data systems are in a plurality of locations;

to determine whether a given client of the plurality of clients is allowed access to one or more of the data records based on one or more of a plurality of data access policies;
