Thanks for you reply.
Now I want to use the Postgresql on the linux platform that is free database.It
provides the connection library in c/c++.It is not difficult to connect the
Postgresql.and I will export the packet summary information(such as
ip.src,tcp.port,dst.ip,dst.port,data len...)into the database.Exporting these
information into database is good to the statistics work.It can statistic data for
the week or the month.
I now am not sure to how to do it.You suggestion of "export to pdml" looks like a
good idea.Can you give me some document of pdml? I will study it and then make the
decision how to do it.
Thanks

format, this would be difficult, as it only saves the raw binary packet data
without any additional dissected info.

still required a mechanism to choose which Ethereal fields have to be exported to
the file (like in the first option).
