Abstract

A method, system, and storage medium for providing versioning of data by associating a version number having a value with a data item, establishing a table for storing a most recent version of the data item, establishing a second table for storing all versions of the data item other than the most recent version, storing the current version of the data item in the first table, storing all other versions of the data item in the second table, and determining the version of said database data item based on the version number and storage location of the database data item.
