PyPerSyst shares certain things in common with Prevayler, but has gone beyond the limited features provided by Prevayler. In particular, PyPerSyst provides base classes with features common in database management systems. I don't think anyone that conducted a serious evaluation of PyPerSyst would be troubled by the fact that I call it a DBMS[1]. [1] http://wikipedia.org/wiki/DBMS
