Software updates that cause changes to a database accessible by software can be identified. A first database can be modified using first instructions associated with a first software update to generate a first modified database, and a second database can be modified using second instructions associated with a second software update to generate a second modified database. A difference between the first and second modified databases can be determined, and one or more instructions of the first or second instructions that caused the difference can be identified based on the difference. The first and second instructions can be converted into operations that, when performed against the first and second databases, result in first and second many-to-many tables being generated. The many-to-many tables can be queried to identify the operations associated with the difference between the first and second modified databases.
