Transfer Objects

The following transfer objects generally apply to relational database plug-ins in the OPC Router.

• DB Select transfer object for reading records from tables and views.
• DB Insert transfer object for writing new records to tables and views.
• DB Update transfer object for updating existing records.
• DB Delete Transfer Object for deleting records.
• Stored Procedures Transfer Object for calling stored procedures via relational database plug-ins.
• DB Log Table Transfer Object for comparing the structure of a table and subsequently writing the records.

In current versions of the OPC Router, table- and view-based database accesses are no longer bundled into a single general transfer object but are divided into separate transfer objects.
