In the case of direct connections through JDBC and ODBC, a license will be required for each individual user directly connecting through JDBC or ODBC. There will not be an additional license required for the individual's machine or device through which such access is made.
It is your responsibility to ensure you acquire the appropriate number of licenses for the anticipated use of the CMS, and to properly determine how many direct connections to the database will be required.
You are only licensed and allowed to make direct connections to the database up to the number of licenses you acquired.
If additional licenses are required, you are obligated to acquire them before making connection to the database.
