ABSTRACT:
A method, system, and computer program product provides the capability to compare data object definitions in a database in a less costly and less time-consuming manner than previous techniques. A method of comparing multiple versions of data item definitions in a database comprises generating a first version of comparison information relating to a plurality of data item definitions in the database by comparing information relating to data item definitions obtained from a first source and information relating to data item definitions obtained from a second source and generating a second version of comparison information relating to a plurality of data item definitions in the database by comparing information relating to data item definitions obtained from a first source and information relating to data item definitions obtained from a second source to the first version of comparison information.
