I think it would be more normal to write the information to files and
then have a cleanup process insert those files into the database and
delete the files. This will keep you from having long running transactions
help open for the duration of a simulation. If you don't want a separate
cleanup process, you could have the simulation process take care of
importing the data after the calculations have been completed.
