Using Postgresql 8.2.11 on Ubuntu 7.10.

I am writing a J2EE project but do not want user specific schemas because this application sits on a production floor and any production employee can walk to a workstation and access the database to punch work time. I know that the public schema is not supposed to be used.

Is the best practice to make one schema for the database and then delete public?

Will using a schema other than public cause problems for users accessing the database with ODBC from Windows?

Thank you,
Margaret.
