The OpenACS system is made up of OpenACS, AOLserver and either Oracle or 
PostgreSQL.

This is roughly the same division of responsibilities as I imagine the 
future combination of Plone, Zope3, and ZODB4 will have.


The OpenACS framework requires knowledge of the configuration languages 
of Oracle or Postgres, of AOLserver and of your chosen RDBMS.

If you want to use stored procedures, you have the choice of all the 
languages that PostgreSQL allows you to use. You'll need to use Tcl, as 
that's what AOLserver and OpenACS use. You'll need to use SQL. It is 
common to extend AOLserver in C. AOLserver has its own templating system.

So, that's at least two configuration languages, a programming language, 
a scripting language, a database query langauge, and a templating language.

People also use the add-on XSL-T module. I'm not sure whether to 
classify that as a templating language or a programming language.


I don't actually use ACS so I might be a bit inaccurate in what I said 
above. If so, perhaps someone more knowledgeable can correct me.
