In this example, data is downloaded from a legacy database on a mainframe computer into a SQL Server 6.0 database on a server and is replicated to any number of subscription servers. This might be used, for example, in a large retail environment where sales and inventory information is entered at point-of-sale terminals and maintained on the mainframe but data is analyzed and management reports are created on the server and distributed to regional offices using SQL Server replication.
For information about implementing this scenario, see Chapter 15, Advanced Replication.
