Abstract
An architecture for processing a plurality of transactions from a single point of initiation is disclosed. The initiating computer selects a terminal identification token, and associates the token with a transaction request, thereby ensuring the association of the transaction with a unique terminal identification despite being originated by the same terminal. The tokens are obtained from a token table, which contains a row for each token defined to the system. The table includes a column for the token, a column that identifies a system with which the token may be used, and a column that identifies a date and time field indicating when a particular token was selected for use. A null value in the date-time field indicates that the token for that row is not in use. A query operation selects a token with a null date-time value, and a set operation sets the date-time value to the then-current time to mark it in use. At the conclusion of the transaction, a set operation sets the date-time value to null, enabling the token to be reused for another non-concurrent transaction.
