Abstract: A computerized enhanced discreet coupon (EDC) processing system processes shopper EDC(s) using a scanner and a processor. The scanner scans purchased items. The processor generates tickets corresponding to the purchased items, syntactically validates shopper EDC(s), semantically checks the EDC(s), and authenticates the EDC(s). If an EDC is authentic, then the processor compares the EDC against the ticket to determine if the EDC qualifies, and if so, then the EDC is redeemable. Authentication can be accomplished by, for example, comparing EDC rule(s) and/or rule identifier(s) against genuine rule/identifier sets. Genuine rule set includes a qualifying rule and a redemption rule.

Abstract: Techniques for performing test adaption and distribution for customer storage systems in accordance with a customer knowledge base. The techniques can include sending, by each customer storage system, data to the customer knowledge base. The data includes, for each customer storage system, a version of a data storage application and associated system configuration and parameters. In response to a query from a QA testing system, the data is migrated from the customer knowledge base to a QA database. The QA testing system analyzes the data to determine the most common system configuration, parameters, and data storage application version for most of the customer storage systems. The QA testing system adapts a test plan for testing the data storage application to conform with the most common system configuration and parameters and executes an application upgrade plan on QA storage appliances pre-prepared in accordance with the most common data storage application version.
