Abstract
Methods and systems are disclosed for tracking change data in a database. A database, stored at a computer system, is accessed with a plurality of data written to fields in the database, wherein each data in the fields comprises a record header. Data is changed in at least one field of the plurality of data in the database via the computer system, wherein the changing the data changes the record header for the at least one field. A transaction identification (ID) is stored in the record header for each change to the at least one field. A flag is created in the record header signaling the change to the at least one field. 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 and identifying the flag.
