Dear Peter,
At CORIOLIS in-situ data center, we are
starting to develop an opendap server directly connected on our ORACLE
RDBMS which contains the full profiles (date, position,
measurements...) managed by the CORIOLIS data center.
We would like to disseminate the profile
datasets, as DAPPER does : a sequence of location (position + date)
containing sequence of profiles (parameter list) containing sequence of
measurement (for each vertical level).
Our server has to be a web application
which is easy to deploy on existing tomcat server.
We're now looking for the best framework
to start with :
2) DRDS (
http://www.opendap.org/download/drds_server.html)
: it is a good model for us because it is easy to connect to a RDBMS
but it doesn't seems to handle
sequence
of sequence ? We could add that function to DRDS but we would like to
be sure the DRDS release will benefits of the future improvments of
Java-DAP.
3) With Dapper we should set up and
maintain a mysql server containing information copied from our Oracle
Database. Moreover, we will not benefit from the indexation of our data in
Oracle (qualitiy flags, vertical levels...) to improve the performance
of the request (dapper reads netCDF files).
4) Anagram seems to be a good candidate
but, firstly, we are a little bit afraid because only GDS
(GrADS-server) seems to be made from that framework. Secondly, we will
need specific filters at the upper layer of the Anagram architecture
(in order to prevent overload by counting the requested record in the
database).
What would you recommend in our case ?
Thanks for your help,
Bye,
Thomas and Arnaud.
