OLE DB Provider for HDA
The OLE DB provider for HDA can be used to retrieve historical data from the
800xA System.
System 800xA history 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 History.
