    • A subscriber management system includes at least one Data Directory Server (DDS) located between one or more transaction generators and one or more data servers. The DDS efficiently routes transactions and provides data location functions. The DDS provides high data availability, high on-line transaction rates, batch capabilities, scalability and maintainability. In particular, based upon internal rules within the DDS and the particular transaction type, the DDS routes transactions to the appropriate server(s). Transactions are classified according to where they may be executed. Specifically, transactions may be classified as SPECIFIC, ANY or ALL. A SPECIFIC transaction must be processed at one or more specific servers irrespective of the accompanying arguments. An ANY transaction may be processed at any of the enterprise servers and selection is made randomly. Finally, an ALL transaction requires sequencing through each of the data servers within the enterprise and repetitively performing the transaction.
