Check out our new website for updates and the NWNX forum: www.nwnx.org ! The Neverwinter Nights Extender (NWNX) is a solution that adds new functionality to the dedicated server. It dynamically loads libraries into the server that can perform various tasks, like ODBC database connectivity. You can create your own NWNX module starting with version 2.5 and do things that you can't even dream of in NWScript.
About the ODBC interface: Unlike other persistence systems, the Avlis Persistence System (APS) and the underlying NWN Extender 2 read and write information from database servers like MySQL or other products on the fly and make information stored in the database available in real-time.
