Relational Database Transfer Objects

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

• DB Select for reading records from tables and views.
• DB Insert for writing new records to tables and views.
• DB Update for updating existing records.
• DB Delete for deleting records.
• Stored Procedures for calling stored procedures via relational database plug-ins.

In current OPC Router versions, table- and view-based database access is no longer bundled into one general transfer object, but split into separate transfer objects.
