A web server manages and provides web pages to clients across the Internet or an Intranet. The web server hosts the pages, scripts, programs, and multimedia files and serves them using HTTP, a protocol designed to send files to web browsers and other protocols. A web server''s traditional function is to serve static HTML (and more recently XML) pages.
A workflow is an abstraction on a business process focussing on the flow of digitalised documents or objects, respectively. Human activities and decisions in the context of business processes are normally left out or taken into account with respect to their interaction with application systems only.
A Workflow Management System (WfMS) is a system that defines, creates and manages the execution of workflows through the use of software, running on one or more workflow engines, which is able to interpret the process definition, interact with workflow participants and, where required, invoke the use of IT tools and applications.
A workflow model represents a workflow type. The representation should support all concepts required for the intended automation; hence, it can contain aspects that are not represented in the corresponding business process model.
