Hi, I wrote some code that transforms the data available on the US FDA's website at: http://www.fda.gov/cder/ndc/ into Berkeley DB databases in one file (db3) and also an XML file that describes the databases. Instructions on building are contained in the README file and the source code to build may be found at: http://www.soggytrousers.net/repository/ndc-data-create-db-0.1.tar.gz I plan on using the database in a Gtk+ GUI app that is not long underway. Regards, Elizabeth
