    abstract = {Web services based on the service-oriented architecture framework provide a
      suitable technical foundation for making business processes accessible within
      enterprises and across enterprises. But to appropriately support dynamic
      business processes and their management, more is needed, namely, the ability to
      prescribe how Web services are used to implement activities within a business
      process, how business processes are represented as Web services, and also which
      business partners perform what parts of the actual business process. In this
      paper, the relationship between Web services and the management of business
      processes is worked out and presented in a tutorial-like manner.},

    abstract = {Information integration has two fundamental aspects, data integration and
      function integration. Function integration is based on flow technology and
      adapter technology, and both of these add powerful capabilities to information
      integration. They provide access to a huge variety of data sources, such as
      standard applications, home-grown backend systems, and Web services. For
      accesses that are not restricted to read operations, flows can help in managing
      units of work across these data stores. When a database system is coupled with
      a flow engine, all of these capabilities are made available to database
      applications.},
