Mature SGBD in Perl with a web interface
WODA is an easy to use web database, with graphical frontend and backend. Built with beginners in mind, it is far easier than any other tool I know, while remaining powerful for advanced users (Perl langage is directly available). It manages semi-relational multimedia databases and allows them to be defined, maintained, added-to, modified, and queried entirely through the web interface without programming. It comes from the 90's and thus is very low in computer resources. Žiga Turk, Woda original author, is also the creator of the famous Virtual Shareware Library (that later evolved into shareware.com) and the former Minister for Education, Science, Culture and Sports in the Government of Slovenia.
