This page aims to outline outlines the history support that is anticipated to be part of Activiti 5.0.



The history module provides access to historic process execution data and acts as a base data provider for basic process execution reports and statistics. For In an initial version, the history module should just provide enough information to feed simple statistical reports and queries about process instance / activity instance executions and their executon times.

Semantics: History vs. Audit

While history is focussing on the fact that and when a specific process or activity has been executed and how long it took to execute it, audit aims for providing comprehensive information on what exactly has been done during a process execution. Typically, the data provided by history builds the base for creating reports and statistics while audit aims for satisfying the regulatory/legal requirements of providing traceability and information on who changed what and from what value to what new value. Due to this different requirements, the natural data model for history and audit differ fundamentally: a history data model contains a consolidated view on executed process steps, optimized for querying, an audit data model in contrast focus on persisting the actual events together with the context data (user, condition evaluations, process data, ...) needed to trace the change.
