Abstract: A method for storing transaction data for an application in a wireless messaging system is disclosed. Applications can be used to allow paging messages to be entered into a wireless messaging system from external systems such as E-mail or the World Wide Web. Such applications may be implemented on an external application platform that includes the hardware system and system software required by the application. Applications often require the use of certain type of transaction data that has traditionally been stored in an application database designed specifically for this purpose by an application developer. The present invention provides a method for storing such transaction data without requiring the application developer to create a separate database. In the past, the development of such databases has been a significant burden on application developers.
