Indirect persistent storage of data in a file that is associated with an
application program and is capable of having an embedded OLEObject
includes creating the OLEObject by way of a Component Object Model add-in
that supplements the application program, and using the OLEObject to
store the data in the file. The OLEObject is marked so that it is hidden
from a user of the application program. After loading a file that was
previously saved and closed, the OLEObject is initialized, and the stored
data is retrieved. The add-in may be a reporting add-in that queries a
database, such as an OLAP database.
