Accessing 800xA via OLE DB

800xA Core supports OLE DB for DA and HDA.

OLE DB Provider for DA

The OLE DB Provider for DA can be used to retrieve real time process data from

the 800xA System.

The real time process data is accessed through the OLE DB provider with a

command syntax. Furthermore, it is possible to create a short reference to history

data that is to be exposed through the OLE DB provider. The purpose of this is

twofold; you can decrease the complexity and length of the command and the

limitation in command length, that some report clients have, can be circumvented.

Each short reference is a generic object placed in the Library Structure and includes

an aspect called OLE DB Access Table for DS.

The OLE DB Providers may be incompatible with some reporting packages

because of different standard interpretations.
