A computer program for software difference comparison is provided. The program extracts data from the files on the hard disk, including data such as symbols extracted from symbol tables, APIs extracted from help files, and/or configuration information. This information may be collected at two or more different times, for example, before and after a version of software is updated to a new version of the software. The collected data is extracted into a relational database. The relational database may be used to determine the differences between multiple versions of software, or between one piece of software and another.
