Abstract
In a method for tracking change data, data is changed in a field of a plurality of data in a database at a computer system, where the plurality of data is included within a base table of the database, the base table including an original state of the plurality of data, where changing the data changes a record header for the field within a change data table of the database, where the change data table includes changes made to the base table. A flag is created in the record header of the data signaling the change to the field within the change data table. Successive versions of the database are linked together such that a subscriber accessing the database can automatically view a current version of the database with the change by accessing the record header of the data and identifying the flag within the record header of the data.
