Abstract
Embodiments of the present invention disclose a method, computer program product, and system for detecting changes in database schema. The embodiments may include receiving a first database schema. The embodiments may include creating a first value corresponding to the first database schema by utilizing a compressed value algorithm. The compressed value algorithm may create a single value corresponding to each database schema. The embodiments may include receiving a second database schema. The embodiments may include creating a second value corresponding to the second database schema by utilizing the compressed value algorithm. The embodiments may include determining whether there is a difference between the first database schema and the second database schema by comparing the first value and the second value.

15. A computer system for detecting changes in database schema, the computer system comprising:
one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage devices, and program instructions stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, the program instructions comprising; program instructions to receive a first database schema, wherein the first database schema is metadata corresponding to a first database; program instructions to create a first value corresponding to the first database schema by utilizing a compressed value algorithm, wherein the compressed value algorithm creates a single value corresponding to each database schema; program instructions to receive a second database schema, wherein the second database schema is metadata corresponding to a second database; program instructions to create a second value corresponding to the second database schema by utilizing the compressed value algorithm; program instructions to determine whether a difference exists between the first database schema and the second database schema by comparing the first value and the second value. - View Dependent Claims (16, 17, 18, 19, 20)
