Transportable logic to facilitate a large calling card transaction network supporting dynamic changes

摘要

A dynamic transaction network having a management station, a terminal, and a database. In response to a transaction request from a caller, the terminal accesses information stored in the database via transportable logic. The transportable logic derives the location of relevant information in the database array from input characteristic(s) of the transaction request. The transportable logic stored in the terminal is updated with transportable logic stored in the management station if the terminal determines that there is a difference between its transportable logic and the management station's transportable logic. Some differences may include a change in the number of databases on the network, a change in the number of terminals on the network, or a change in the location of the information stored on the database.
