Database compression oriented to combinations of record fields

A computer system comprising:

• a processor;
• and
• a computer-readable memory coupled to the processor, the memory comprising instructions that when executed by the processor perform:
• determining one or more combinations of fields of a record of a database that satisfy a frequency criterion indicating that access frequencies of the one or more combinations of fields are higher than an access frequency threshold;
• reorganizing the record based on the one or more combinations of fields to store fields of each combination of the one or more combinations of fields in a respective contiguous storage space;
• and
• compressing the reorganized record by applying a compression scheme to the one or more combinations of fields.

A computer program product, comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:

• determine one or more combinations of fields of a record of a database that satisfy a frequency criterion indicating that access frequencies of the one or more combinations of fields are higher than an access frequency threshold;
• reorganize the record based on the one or more combinations of fields to store fields of each combination of the one or more combinations of fields in a respective contiguous storage space;
• and
• compress the reorganized record by applying a compression scheme to the one or more combinations of fields.
