Is there a plan to support different backend databases? My system currently uses MySQL for everything. A better question is how the CNS software makes database queries? If it uses perl_db like prizm did then getting MySQL to work wouldnt be a problem.
Currently there are no plans to support different backend databases. CNSS is tightly integrated with PostgreSQL, performing some of our statistic aggregation directly using PostgreSQL functions. I’m not sure how well this could be transferred over to MySQL.
The CNSS Java backend uses a PostgreSQL JDBC driver (http://jdbc.postgresql.org/). The PHP layer uses pg_connect (http://www.php.net//manual/en/function.pg-connect.php). The PHP layer is required for GUI functionality.
