Workflow engine

From Wikipedia, the free encyclopedia

Workflow engine is a software application meant to manage and execute modeled business processes.

It is a key component in workflow technology. It will typically make use of a database server.

The workflow engine will interpret events such as documents submitted to the server or due dates expiring and act on these events according to the defined business processes. The actions may be anything from saving the document in a document management system to issuing new work by sending an e-mail to users or escalating overdue work items to management. In other words you can say that, Workflow Engine facilitates the flow of information, tasks and events or you can say that it is the heart of a workflow application.
