OrgPublisher Enterprise Edition creates two files when you build charts using an ODBC connection. One of these files uses the .odb extension and contains the connection information to your database. The second file uses .otm and contains the formatting. The same name is used for both files and the .otm is saved automatically when you save the .odb. If you created a connection called test, you will have a test.odb and a test.otm file located in the same directory.
