ABSTRACT:
A database version control method assures consistency of computer information that is resident in first and second data repositories. Each data repository is adapted to transfer changes in the computer information to the other data repository and further includes a version control procedure. The version control procedure implements the steps of: producing an independent change package data file (ICPF) in the first repository which indicates a change relating to a line of the computer information, the ICPF including a change order value which is temporally related. The ICPF is transferred to the second repository and is arranged in the computer information in the second repository in a change order value manner with respect to all other ICPF's evidencing changes to the same line of the code. The arranging of the newly inserted ICPF takes into account a creation time notation that is included in the change order value. The version control procedure further employs an absolute address accompanying each section of change data in an ICPF which lists the absolute addresses of all intermediate lines of code that are relevant to the latest ICPF. Even if the receiving repository does not include data for each listed address, the receiving repository employs the missing absolute address as a place holder--to await later possible insertion of the actual data.
