Dbix::sequence is intended to give easier portability to perl database application by providing a database independent unique id generator. this way, an application developer is not bound to use his database's sequence or auto_increment thus making his application portable on multiple database environnements.

this module implements a simple spin locker mechanism and is garanteed to return a unique value every time it is called, even with concurrent processes. it uses your database for its state storage with ansi sql92 compliant sql. all sql queries inside dbix::sequence are pre cached and very efficient especially under mod_perl.
