PHP/MySQL Experiments

The CRUD

The CRUD is an experiment in [C]ollaborative [R]ealtime [U]ser [D]omains - virtual spaces that will allow the users to navigate, build and textually embellish. This is sort of like a people-less online environment (in cyberspace, no one can hear you scream).

It was written from scratch by wOnko because he wanted a collaborative building tool and was used to things like MUDs and MOOs and because it was a nicely contained exercise that might lend itself to instruction.

Original rantings on what the CRUD should look and work like should be read first. Conceptual Modelling for the CRUD is also available.
