Developing a reusable workflow engine

Every time a workflow solution is conceived there is a large amount of functionality that is eventually reinvented and redeveloped from scratch. Workflow management systems from academia to the commercial arena exhibit a myriad of approaches having as much in common as in contrast with each other. Efforts in standardizing a workflow reference model and the gradual endorsement of those standards...

Media360 Workflow-Implementing a Workflow Engine Inside a Database

I describe a Workflow Management System, where the workflow engine is implemented inside a database. The focus here is on the architectural approach and on the lessons learned from a commercial implementation in the workflow component of the Informix Media 360 content management solution. Conceptually, the two main primitives of workflow are activities, which represent the work items of a large...

Workflow Process Engine Interface External Workflow Engines

We introduce the ActivityFlow speciication language for in-cremental speciication and exible coordination of workkow activities. The most interesting features of the ActivityFlow speciication language include (1) a collection of speciication mechanisms, which provides a workkow designer with a uniform workkow speciication interface to describe diierent types (i.e., ad-hoc, administrative, or pr...

Workflow Engine for Clouds

A workflow models a process as consisting of a series of steps that simplifies the complexity of execution and management of applications. Scientific workflows in domains such as high-energy physics and life sciences utilize distributed resources in order to access, manage, and process a large amount of data from a higher level. Processing and managing such large amounts of data require the use...
