US Patent 7788282 Methods and computer programs for database structure comparison

Methods and computer programs for comparing database structures such as database schemas and descriptions of application programming interfaces are disclosed. The methods involve identifying incompatibilities between information repositories such as relational databases and byte code repositories by extracting a first database structure from a first information repository, extracting a second database structure from a second information repository, filtering relevant sections from each database structure, asymmetrically comparing the relevant sections, and identifying any incompatibilities between database schemas or byte code repositories.
