  • providing as input said data file that contains undifferentiated regions of both text and non-text;

    analyzing said data file using identification rules to differentiate between regions containing text and regions containing non-text;

    repeatedly modifying said differentiated regions containing non-text according to storage preference rules based on a time parameter associated with said data file to reduce storage size such that the storage size gradually reduces as a function of elapsed time;

    compiling said modified regions into a reduced data file; and

    storing said reduced data file in said database.
