Abstract: A method includes defining a file attribute indicator based on an attribute associated with a source file and based on a mapping policy. The source file has a source filename and the source file is migrated to a target system from a source system. The target filename is based on the source filename and the file attribute indicator. The target filename is used by a target application of the target system to process the source file. The target application is the source application configured for use on the target system.

Abstract: An improved data compression method and apparatus is provided, particularly with regard to the compression of data in tabular form such as database records. The present invention achieves improved compression ratios by utilizing metadata to transform the data in a manner that optimizes known compression techniques. In one embodiment of the invention, a schema is generated which is utilized to reorder and partition the data into low entropy and high entropy portions which are separately compressed by conventional compression methods. The high entropy portion is further reordered and partitioned to take advantage of row and column dependencies in the data. The present invention enables not only much greater compression ratios but increased speed than is achieved by compressing the untransformed data.
