Non-SQL Server Publishers
Applies to: 
SQL Server
Publishing data from non- SQL Server sources allows you to consolidate data in Microsoft SQL Server. SQL Server can subscribe to snapshot or transactional data published from an Oracle database. For more information about publishing from Oracle, see Oracle Publishing Overview.
SQL Server supports the following heterogeneous scenarios for transactional and snapshot replication:
Publishing data from SQL Server to non-SQL Server Subscribers.
Publishing data to and from Oracle has the following restrictions:
| Replication | 2016 or earlier | 2017 or later |
|---|---|---|
| Replication from Oracle | Only support Oracle 10g or earlier | Only support Oracle 10g or earlier |
| Replication to Oracle | Up to Oracle 12c | Not supported |
Heterogeneous replication to non-SQL Server subscribers is deprecated. Oracle Publishing is deprecated. To move data, create solutions using change data capture and SSIS.
Caution
This feature will be removed in a future version of SQL Server. Avoid using this feature in new development work, and plan to modify applications that currently use this feature.
Publishing from non- SQL Server databases is ideal for the following scenarios:
| Scenario | Description |
|---|---|
| Microsoft .NET Framework application deployments | Develop with Microsoft Visual Studio and SQL Server while operating on data replicated from a non-SQL Server database. |
| Data warehousing staging servers | Keep SQL Server staging databases synchronized with a non-SQL Server database. |
| Migration to SQL Server | Test your application in real time against SQL Server while replicating the source system's changes. Switch to SQL Server when satisfied with the migration. |
