Enhancements were introduced to the model in run time and modeling capabilities. A new extension of their model, called ETEOR2 [26], includes modifications in the way tasks are defined, in the way the graphical workflow designer for process definition is used, in the way the automatic translations from the definition to the execution module is handled, and in the way multiple infrastructures are integrated and supported. 4 ....

....security management, and business processoriented systems management. However, there are also workflow implementations that focus on vertical markets. For example, Teoss 2000 from InConcert [60] targets the telecommunications market; HP s Changengine [56] targets business administration; METEOR 2 [116] provides workflow solutions for the health care industry; etc. But the key point here is that a wide range of application domains can benefit from workflow technology. 2.2.3 Monitoring and History The separation of process logic from the application components enables workflow to tap into the ....

A CORBA based runtime employs the CORBA services for communication, distribution, transactions and fault tolerance. A Web based runtime targets organizations that don t have the resources to manage a CORBA product [116]. In this case, tasks consist of CGI scripts coded in C C or Perl. HTML documents and forms with hidden tags implement data flow between tasks. 2.5.4 Examples Summary The three workflow systems presented in this section have different emphases. TriGS flow focuses on techniques specific to ....

....briefly sketched. In both works, components can coordinate their processes and thus share information on their process models. This is certainly necessary in design applications such as software engineering, while it is not feasible in the general workflow applications we consider. Sheth et al. [15] discuss workflow execution in heterogeneous environments. However, they focus on the access to heterogeneous resources, such as databases, using a variety of infrastructure technologies (such as ORBs and the Web) They use a single WFMS (METEOR 2 ) and therefore do not consider workflow system ....

....pathset search to avoid generating product automata, but the individual automata can be quite large. Neither of the above approaches can express or process complex dependencies as easily as the present approach. Recently, a distributed prototype was proposed, but it is not given a formal basis [13]. In our system, events variously wait, send messages to each other, and thereby enable or trigger each other. This appears intuitively similar to Petri nets, which can be applied to workflows [17] However, our goal was to find a way to characterize workflows that may be weaker than general ....

The point was not to make interoperate COTS but to extend Marvel with file system control. In Meteor [31], Many systems have focussed on the concept of point of view [19] 25] 29] 32] 34] These work address the problem of how to model a complex system by a combination of point of view, which bears some similarity with our approach.

....(CLF) a transactional rule based scripting language for specifying client=server interactions. As in Aurora, scripts are interpreted rather than compiled, thus enabling flexible resource binding. This is also a major difference with the workflow architecture proposed by the METEOR 2 project [16], which relies on a code generator to produce task management components and wrappers (both for human and automated tasks) that need to be manually installed at each participating site. Each wrapper includes a hard wired specification of the immediate predecessors and successors of the task that ....

....components are encapsulated in containers which expose a uniform interface for management purposes. This container framework, which enables detailed monitoring and control of active tasks and long running compositions of tasks, is a major distinguishing feature of our approach. The METEOR 2 [61] and Infospheres [24] projects also take the approach of establishing networks of components. This reduces the amount of data to be passed between processing entities, as compared to approaches similar to the INCAs model. METEOR 2 has developed two prototypes, ORBWork based on CORBA and WebWork ....

....in most settings where workflows are of interest. ffl Most existing scheduling approaches are centralized. Klein, 1991a] claims a purely distributed scheduler, but gives few details even in the longer article [Klein, 1991b] Recently, some distributed prototypes have been proposed, e.g. [Sheth et al. 1996], but these are not given a formal basis. Philosophical Remarks This paper seeks to better delineate the fundamental limits of workflow scheduling. Although we propose advanced techniques for scheduling, we obviously cannot go beyond what distributed computing allows, e.g. in terms of the ....

Work ow Management Systems have met with some success. One reason for the limited success is that realworld processes are very complex. Furthermore, since real world processes in business, engineering and science are ever changing, a WfMS should support such change. The ....

....necessary to define it as a collection of tasks. There are data and control dependency relationships among these tasks. WfMC [WfMC96] considers two kinds of tasks, automated and manual. While in some commercial products or research systems, more kinds of tasks are introduced. For example, METEOR [SKMW96, SK99], a WfMS developed at the Large Scale Distributed Information Systems (LSDIS) Lab, University of Georgia, supports some more kinds of tasks such as transactional, non transactional, compound (network) two phase commit, manual and so on.
