Abstract: A market management system is designed to manage energy industry standardized transactions between energy providers and utility distribution customers. The system includes business process and transaction validations along with transaction tracking. The market management system processes transactions in its own data format but stores the transactions in a client's customer information system (CIS) using the CIS's data format. Using only the CIS database for transaction storage eliminates the need to synchronize transaction records in the CIS database with records in a market management database. Exception management is integrated with the CIS to eliminate duplication of effort. The market management system's functionality is scalable such that varying levels of service may be provided to customers. Predetermined business rules may be customized for the purpose of validating transactions.
