SQL Server 7.0 includes an OLE DB driver for Oracle, which facilitates the migration and movement of data and tables to and from Oracle servers to SQL Server 7.0 servers. DTS is one method that can be implemented to migrate and transform data. Data also can be migrated from one Oracle table to another using SQL Server 7.0 and DTS. The OLE DB driver for Oracle provided with SQL Server 7.0 allows an Oracle database to be a Subscriber in a SQL Server 7.0 Publisher without using a third-party product. In contrast, Oracle requires a SQL Server gateway for SQL Server to participate in Oracle replication.
