On Evolution of XML Workflow Schemata
نویسندگان
چکیده
XML is arising as a new format to represent the enterprises' business processes, since it is a exible and interchangeable language. In the work ow area, one of the most discussed questions is the evolution of the work ow representations, in order to meet new requirements. Despite the number of existing proposals, none of them deals with evolution of work ows that use the XML syntax. In this paper, we present a proposal for work ow evolution in which the work ow schema is represented in XML. The proposal is based on versioning concepts, that allow the storage and use of di erent versions of the same work ow schema. An evolution architecture is proposed, in order to separate the involved concepts in a set of managers. Two of these managers are discussed in depth in this paper { Version Manager and Modi cation Manager. The Version Manager handles (schema) versions and the Modi cation Manager controls the changes that can be applied over them.

XML Schemata Inference and Evolution
This work addresses the automatic generation of conceptual models for XML-oriented databases, which in many cases have little or no support for schemata. Our techniques are based on both an incremental clustering algorithm, which groups together the incoming XML documents according to their structural similarities, and a schema inference method, which maintains dynamically the schema of each de...
متن کاملSchemata Evolution and Building Blocks
In the light of a recently derived evolution equation for genetic algorithms we consider the schema theorem and the building block hypothesis. We derive a schema theorem based on the concept of effective fitness showing that schemata of higher than average effective fitness receive an exponentially increasing number of trials over time. The equation makes manifest the content of the building bl...
متن کاملSchemata as Building Blocks: Does Size Matter?
We analyze the schema theorem and the building block hypothesis using a recently derived, exact schemata evolution equation. We derive a new schema theorem based on the concept of eeective tness showing that schemata of higher than average eeective tness receive an exponentially increasing number of trials over time. The building block hypothesis is a natural consequence in that the equation sh...
متن کاملEvolution von XML-Schemata auf konzeptioneller Ebene - Übersicht: Der CodeX-Ansatz zur Lösung des Gültigkeitsproblems
If new requirements arise models have to be adapted to them. Additionally, the instances based on these models have to be adapted as well otherwise they might not be valid anymore. The same applies to the XML schema as a model and widely accepted description for XML documents. One solution for solving the occurring validity problem is the here described XML schema evolution. On the basis of a c...
متن کاملIntegrierte Dokumenten- und Ablaufmodellierung von E-Business-Prozessen
Aufgrund der starken Zunahme internetbasierter E-BusinessAktivitäten werden Sprachen für die Modellierung von E-Business-Prozessen immer wichtiger. Ziel der Modellierung ist die formale Darstellung der organisationsübergreifenden Prozesse und aller prozeßrelevanten Objekte. Zur integrierten Modellierung von E-Business-Prozessen und den prozeßrelevanten Dokumenten wird daher eine neue Variante h...
