Workflow instance

A workflow instance is a running instance of a workflow definition . A single workflow definition will generate an unlimited number of workflow instances. For example, you can have a single workflow definition for order processing, and for each order, you will have a workflow instance. In a workflow definition you might have a variable named "Order number". Each workflow instance will have its own order number, and the variable "Order number" will have a different value. Each workflow instance will have its own state and internal variable values. A workflow instance can be started, running or finished. All workflow instance records are kept in the database, even the finished ones.
