Your app

Only communication with enginethrough interfaces!

FEATURES

• Clean client API (ideally you shouldn't be using anything else)

• Simplified DB schema• runtime vs historical data separation!• eg process instance is in DB only during execution, afterwards it is deleted and stored in a history table

• Performance boost (and no method-chaining)

• Fancy web console (GWT)
