ABSTRACT Organizations are living a paradigm shift in the development of their information systems: from data to process. The objective is tho emphasize business process to obtain flexible and agile architectures and hence to be capable to face the continuous changes that take place in the environment where the organizations make their business. The purpose is making independent the business process management of software applications and so to achieve that a change in business rules have not a big impact in applications software code. To carry out this goal it will be necessary to build Business Process Management Systems. A similar revolution took place when the introduction of the relational database model cause applications to separate their data model of their logic. This process oriented architectural change can be better obtained if the organization has a previous service oriented architecture. Moreover, in this case the organzation can make a externalization of their functionality by means of web services. Business process could allow to combine services using choreographies and orchestration. This work shows a BPMS general description, studying their relation with the integration of applications and services architectures. Las organizaciones están viviendo un cambio en el paradigma de desarrollo de sus sistemas de información: de los datos a los procesos. La finalidad que se persigue con ello es enfatizar los procesos de negocio para conseguir arquitecturas más ágiles y flexibles adaptables a los continuos cambios que se producen en los mercados en los que las organizaciones desarrollan su negocio. El objetivo es independizar la gestión de los procesos de negocio de las aplicaciones, para que cualquier modificación en la lógica de negocio no afecte al código de las aplicaciones. Para ello se utilizarán sistemas de gestión de procesos de negocio (BPMS). Es una revolución similar a la que se produjo al asilar la gestión de los datos de las aplicaiones, con la llegada de las bases de datos y el modelo relacional. Este cambio de arquitectura, orientada a los procesos, se consigue más fácilmente si la organización dispone ya de una arquitectura orientada a servicios que además le permitirá exteriorizar su funcionalidad en forma de servicios web. Los procesos de negocio combinarán estos servicos mediante orquestación y coreografías. En este trabajo se aborda la descripción general de los BPMS, estudiando su relación con la integración de aplicaciones y arquitecturas de servicos.

    ABSTRACT: Based on a rigorous analysis of existing workflow management systems and workflow languages, a new workflow language is proposed: yet another workflow language (YAWL). To identify the differences between the various languages, we have collected a fairly complete set of workflow patterns. Based on these patterns we have evaluated several workflow products and detected considerable differences in their ability to capture control flows for non-trivial workflow processes. Languages based on Petri nets perform better when it comes to state-based workflow patterns. However, some patterns (e.g. involving multiple instances, complex synchronisations or non-local withdrawals) are not easy to map onto (high-level) Petri nets. This inspired us to develop a new language by taking Petri nets as a starting point and adding mechanisms to allow for a more direct and intuitive support of the workflow patterns identified. This paper motivates the need for such a language, specifies the semantics of the language, and shows that soundness can be verified in a compositional way. Although YAWL is intended as a complete workflow language, the focus of this paper is limited to the control-flow perspective.

    ABSTRACT: This book offers a comprehensive introduction to workflow management, the management of business processes with information technology. By defining, analyzing, and redesigning an organization's resources and operations, workflow management systems ensure that the right information reaches the right person or computer application at the right time. The book provides a basic overview of workflow terminology and organization, as well as detailed coverage of workflow modeling with Petri nets. Because Petri nets make definitions easier to understand for nonexperts, they facilitate communication between designers and users. The book includes a chapter of case studies, review exercises, and a glossary. A special Web site developed by the authors, www.workflowcourse.com, features animation, interactive examples, lecture materials, exercises and solutions, relevant links, and other valuable resources for the classroom.
