DataNucleus supports persisting objects to Excel documents (using the
datanucleus-excel plugin).
It makes use of the Apache POI project.
Support for Excel is in its early stages and will be enhanced in future releases.
If you wish to help out in this effort either by contributing or by sponsoring particular
functionality please contact us via the DataNucleus Forum.
DataNucleus supports the following mode of operation, file-based
The following persistence properties will connect to a local file on your local machine
datanucleus.ConnectionDriverName=
datanucleus.ConnectionURL=excel:file:D:/myworkspace/test.xls
datanucleus.ConnectionUserName=
datanucleus.ConnectionPassword=
The following are known limitations of the current implementation
-
Relationships between objects are not supported currently and wouldn't be easy
to support since Excel doesn't have the concept of a relation
-
Datastore Identity is not currently supported
-
Optimistic checking of versions is not supported
-
Identity generators that operate using the datastore are not supported
