Ektron CMS400.Net Reference
Ektron CMS400.NET leverages Windows Workflow Foundation for order processing.
Windows Workflow Foundation is a framework that enables users to create system or human workflows. It consists of a namespace, an in-process workflow engine, and designers for Visual Studio 2005/2008. It comes with a programming model, a re-hostable and customizable workflow engine, and tools for quickly building workflow-enabled applications on Windows.
Windows Workflow Foundation gives site developers complete control over how your store “works”. The workflow is completely extensible and can integrate with third-party ERP/CRM systems. There are default Ektron activities such as email notification and inventory checks, and the workflow can be customized to match the organization's business processes.
