Reduce the storage requirements of the database system in a data compression

2010 
The present invention discloses a method for reducing data storage requirements of the database system, system, and computer program product. One embodiment includes: based on a predetermined threshold level and compression boundary, determining at least one candidate data from at least one row has a fixed length data types of the compressed data in the database; candidate data according to the boundary of compression in at least one row is determined providing at least one bit; and storing the at least one row in the database system as compressed data. The candidate data to be compressed includes a column identified fixed length, the length of the column line of data is not less than a predetermined threshold level, and which comprises at least a bit length of the data to be compressed a candidate that has been determined the bit map. For compression based on a page boundary, which has been determined to be compressed candidate data string including redundant data byte pages of data, the redundant data comprises a byte string match between the multi-column length exceeds a predetermined threshold level data.
