Classification: CPC H  G | IPC G  H

Claim 11:
12. An apparatus for compression of data, comprising:
a memory configured to store instructions; and
at least one processor configured to execute the instructions to perform operations including:
accessing tabulated data in at least two of a plurality of first file formats, wherein the at least two of a plurality of first file formats are incompatible with one another;
extracting attributes from the tabulated data;
dividing the tabulated data into chunks;
processing the extracted attributes and chunks into correlated information;
selecting different compressors and dependency attributes for the attributes and chunks identified in the correlated information;
storing global data for compressors shared across chunks; and
generating a file in a second file format that includes the correlated information and further including information indicative of the different compressors used for compressing the chunks and attributes, wherein the second file format is different from the first file formats; and
generating access control policy information for the correlated information, and integrate the access control policy information into the file of the second file format, wherein the access control policy information includes first information indicating a first level of access for a first portion of the correlated information and second information indicating a second level of access for a second portion of the correlated information, and wherein the second level of access is different from a first level of access.
