Tools for evolving civilizations
It's making something work that's hard.
Historical Platform: Oracle + AOLServer + ACS
The Oracle database is accessed via the database language SQL. Pages served by the AOLServer can contain programs written in the scripting language TCL. These programs are interpreted on the fly to access, query, and add to the database and compile dynamic content.
While Oracle is of course proprietary commercial software, the AOLServer and ACS are Open Source. These three components have been used together to build a great number of commercial and public web services by a number of developers and publishers, most notably by Arsdigita itself.
Current Platform: PostgreSQL + AOLServer + OpenACS
PostgreSQL is an increasingly popular Open Source database system, and the OpenACS is a version of the Arsdigita Community System that has been ported to use that database instead of the traditional and proprietary Oracle system.
The OpenACS is a very exciting development because it allows us to develop and deploy very powerful websites without the hassles of registration or royalties.
