Web-Accessible Scientific Workflow System for Performance Monitoring

摘要

We describe the design and implementation of a web-accessible scientific workflow system for environmental performance monitoring.This workflow environment integrates distributed automated data acquisition with server side data management and information visualization through flexible browser-based data access tools.Component technologies include a rich browser-based client,a back-end server for methodical data processing,user management,and result delivery,and third party applications which are invoked by the back-end using web services.This environment allows for reproducible,transparent result generation by a diverse user base,and provides a seamless integration between data selection,analysis applications,and result delivery.This workflow system has been implemented for several sites and monitoring systems with different degrees of complexity.
