A state engine system is disclosed. The system includes: a CPU and a memory operatively connected to the CPU, the memory including a program adapted to be executed by the CPU and the CPU and memory cooperatively adapted for managing a plurality of objects stored in a database, whose behavior can be modeled by means of a state diagram reacting on external events which occur in a non-deterministic order. The system additionally includes code segment embodied on a computer-readable medium configured and adapted for creating, storing and maintaining state diagram templates in a database. The database includes all states available for the object, the possible state transitions, the events which cause state transitions, and the actions which occur upon state transitions. There is at least one event causing each state transition, and the actions which occur upon a state transition are dependent upon the event that caused the transition.
