In this paper we present and discuss a novel architectural approach supporting the integration among legacy information systems of autonomous organizations. It is based on the use of a data warehouse in a new conceptual role. Namely, we propose to use ...

An important yet open problem in workflow management is the evolution of workflow schemas, i.e., the creation, deletion and modification of workflow types in such a way that the schema remains correct. This problem is aggravated when instances of ...

Traditionally, workflow management systems are used to support static processes, i.e., processes which do not change frequently. This has limited the scope of workflow management. Moreover, the networked economy of the new millennium requires workflow ...

Workflow management systems (WfMSs) are most applicable when processes follow a predictable and repeatable behavior. However, exceptional situations may occur in any process. An important class of exceptions is that of expected exceptions, i.e., of ...

In this paper, we present an approach to global transaction management in workflow environments. The transaction mechanism is based on the well-known notion of sagas, but extended to deal with arbitrary process structures including cycles and savepoints ...

Business processes exhibit concurrent execution, where different and sometimes inter-dependent parts, are isolated and run in parallel. In current workflow tools, this requirement is supported through a synchronization mechanism allowing for the ...

Warehousing and mining sales transaction data to generate summary information, customer profiles, and business rules has become increasingly important in e-commerce. Such summary information and rules have to be extracted from very large collections of ...

This work explores (semi-)automated EC on the WWW. The E-Contracts framework enables EC WWW sites and EC automated tools to present standardized information. This information (1) allows each party to decide whether it wishes to engage in an EC activity ...

Traditional approaches to managing business processes are often inadequate for large-scale, organization-wide, dynamic settings. However with the explosion of electronic commerce applications, increasingly many business processes exhibit these ...

Today, the design of workflow schemas is to a large extent a manual process. Starting with business-process models, developers must make many decisions that are not supported by tools, to finally deliver a workflow schema that can be executed by a ...

Office tasks related to processing of contracts in the insurance business are complex and highly dependent on legal and company-specific formal regulations. On the other hand, the increasing competition strongly influences efficiency as well as quality ...

The Web so far has been incredibly successful at delivering information to human users. So successful actually, that there is now an urgent need to go beyond a browsing human and make information accessible to applications, in order to offer automation, ...
