The benefits of connecting businesses through Web-services- based trading exchanges are huge. These exchanges allow various companies to connect supply chains in various industries or across industries, introducing new efficiencies and ways of buying, selling, and brokering products and services. Connecting businesses through Web-services-based trading exchanges give companies the ability to transact in ways that were never before possible. These exchanges help connect buyers to sellers and provide a shorter procurement trading lifecycle. Having this account, in this work a business processes integration and monitoring system has been developed to automate, integrate and monitor many of the enterprise business processes described as Web services without recurring to large investments in software development and deployment. The contribution of this work consists in a service-oriented architecture that follows the SOA?s principles of improving economical benefits of business collaborations.
