A computer-based method of data replication of data in a programmable
computer system having an ISAM database and a transaction log file, with
the ISAM database having fields of tables and the transaction log file
maintaining all files transactions of the ISAM database, comprising the
following steps. Polling the transaction log file for file transactions
of at least one selected ISAM database fields of tables by at least one
data replication server. Reading the polled file transactions of the at
least one selected ISAM database fields of tables by the at least one
data replication server. Sending the polled file transactions of the at
least one selected ISAM database fields of tables from the at least one
data replication server to at least one relational database whereby the
polled file transactions of the at least one selected ISAM database
fields of tables sent to the at least one relational database is
accessible in real time.
