Abstract: A system for analyzing an information system comprising a computer readable medium; and a set of computer readable instructions embodied in the computer readable medium for transmitting an audit application to a first store controller so that the audit application can generate audit data representing audit information from the first store controller, receiving audit data from the first store controller, transmitting an audit application to a second store controller so that the audit application can generate audit data representing audit information from the second store controller, receiving audit data from the second store controller, determining a comparison basis according to the audit information from the first store controller, comparing the audit date from the second store controller to the comparison basis, generating a set of comparison data resulting from the comparison, displaying items from the second store controller that are different from the comparison basis.
