ABSTRACT:
An improved method and system for comparing database data. Data comparison may be performed either within a database or between two databases. Sets of cyclical redundancy check values may be created, at various points in time. Corresponding cyclical redundancy check values may be compared with each other to determine if the underlying data is different; differences may be displayed. Each cyclical redundancy check value may correspond to a user-determined amount of data within the database. The user-determined amount of data may be: (1) user-specified columns within one of the plurality of tables within the database; (2) a row within one of the plurality of tables within the database; (3) a table within the database; (4) the database in its entirety; or (5) any other subset of the database. A user-determined number of bytes corresponding to a user-determined subset of the user-determined amount of data may be stored for future use.
