Does Abyss Web Server support database X (MySQL, Access, Oracle, etc.)?
Database support is independent from the web server. Actually the web server invokes scripts and they are these scripts that connect to the database and use it. In other words, it is up to your script and to the script interpreter (PHP, Perl, or ASP for example) to connect to the database (MySQL, Access, Oracle, or whatever database you use.) Since Abyss Web Server is able to run PHP, Perl, ASP, and many other languages, database scripting is possible. For more information about how connect to a database, refer to the documentation of the scripting language you use.
