Refer to the Oracle Utilities Network Management System Customer Data Model specification.
Note: The bulk load of customers can be accomplished by running the createSql.exe file that will create .sql file to be run through ISQL.ces, which will populate the customer model. The createSql file should be provided the following command line options to create the sql. (IE. CreateSql -xmlfile create_customers.sql -outputfile product_customer_data.sql.) The -writetodb command can be provided to write the customers directly through to the database with out having to run ISQL.ces < product_customer_data.sql.
