Claim 0:
1. A method for compression of data, comprising:
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;
generating a file in a second file format that includes the correlated information, and further includes information indicative of the different compressors being used to compress 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 integrating 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, wherein the second level of access is different from a first level of access.
