| Zusammenfassung: | Abstract: "Electronic commerce plays a more and more important role in today's economy. An increasing number of firms sell their products online, and portals bundle the services of other firms and offer them to the user thereby acting as one single point of contact. An important aspect in this trend is the composition of various services to form value-added offerings. The new, complex services must be easy to specify and understand and must be executed transactionally. Yet, this is only partly addressed by the technology in use today. The rule-based update language ULTRA covers the whole range from specification to execution and therefore is well-suited to overcome these shortcomings. It provides the necessary features, among them a high-level semantics and compositionality, and implicitly guarantees transactional execution. After an overview of the general ULTRA framework we present an instantiation which can be used to combine an arbitrary set of basic services to obtain new complex services. Among others, the instantiation features a specialized data structure for the internal representation of composed services that can be used for concurrency control and recovery as well. We then develop a suitable evaluation model for this instantiation. It is based on the well-known notion of nested transactions, uses compensation for roll-back and can handle sequential as well as concurrent services. It turns out that the proposed evaluation model only requires that compensation of the basic services is supported and that they take part in an atomic commit protocol." |
