Cycle is PHP DataMapper, ORM and Data Modelling engine designed to safely work in classic and daemonized PHP applications (like RoadRunner). The ORM provides flexible configuration options to model datasets, powerful query builder and supports dynamic mapping schema. The engine can work with plain PHP objects, support annotation declarations, and proxies via extensions.
