A method is provided in which, responsive to a transaction request from a client machine, the transaction request is searched for any key words. If there are any key words present, the associated data and one or more driver parameters are retrieved from the database. The driver parameters are then placed into a data array for processing. Thereafter, control is passed to an XML object processor. While processing the parameter cards, which are the XML object structures, if an embedded tag is encountered, control is passed to a subsequent copy of the program, which then processes the embedded object. The parameter cards for each object may be used to invoke further database calls to retrieve any additional data required to fulfill the object. As each process completes, the "prior" application is run until the object and all associated data have been retrieved and assembled. Once all processes are complete, the processed data is transmitted to the client machine for display.
