TheexplosivegrowthoftheInternetandtheWebhavecreatedanever-growing call for for info structures, and ever-growing demanding situations for info platforms Engineering. The sequence of meetings on complicated info S- tems Engineering (CAiSE) used to be introduced in Scandinavia by way of Janis Bubenko and Arne Solvberg in 1989, turned a major ecu convention, and used to be held each year in significant ecu websites during the Nineties. Now, in its 14th year,CAiSEwasheldforthe?rsttimeoutsideEurope,showcasinginternational researchon info structures and their engineering. no longer unusually, this 12 months the convention loved extraordinary awareness. In overall, the convention got 173 paper submissions, the top quantity ever for a CAiSE convention. of these, forty two have been approved as usual papers and 26 as brief (poster) papers. moreover, the convention obtained 12 proposals for workshops of which eight have been authorized, whereas four tutorials have been chosen from 15 submissions. The technical application used to be prepare by means of a global committee of eighty one specialists. In overall, 505 studies have been submitted, with each member of the committeecontributing.Decisionsonallsubmissionswerereachedataprogram committee assembly in Toronto on January 26-27,2002. Workshop and instructional proposals have been dealt with individually by means of committees chaired via Patrick Martin (workshops), and Jarek Gryz and Richard Paige (tutorials). we want to expand an outstanding “THANK YOU!” to all participants of this system and organizing committees for his or her volunteer contributions of time and exp- tise. the truth that such a lot of busy (and famous!) humans took the difficulty to assist uswiththeorganizationofthisconferenceandtheformationofitstechnicalp- gram speaks good for the way forward for CAiSE and the ?eld of data platforms Engineering.

This e-book encompasses a selection of essays by way of major specialists associated with the phenomenal features of the coed in honour of whom it truly is released, Tullio Treves, who combines his educational heritage along with his functional studies of a negotiator of overseas treaties and a pass judgement on of a global tribunal.

Example text

The „INS“ construct represents the instance-and-class relation. The „ISA“ construct expresses conceptual generalization/ specialization. 2 UCM Use Case Maps (UCM)[1] provide a visual notation for scenarios, which is proposed for describing and reasoning about large-grained behavior patterns in systems, as well as the coupling of these patterns. The UCM notation employs scenario paths to illustrate causal relationships among responsibilities. It provides an integrated view of behavior and structure by allowing the superimposition of scenario paths on a structure of abstract components.

This type of service composition is specified on the fly and requires dynamically structuring and co-ordination of constituent services. – Semi-fixed composition: Here some of the actual service bindings are decided at run time. When a composite service is invoked, the actual composition plan will be generated based on a matching between the constituent services specified in the composition and the possible available services. , it can be searched, selected, and combined with other services. – Fixed composition: a fixed composite service synthesizes fixed (pre-specified) constituent services.

SCPL provides a simple light-weight but powerful mechanism for service composition nesting and substitution, composition extension, and dynamic service selection. A Service Composition Execution Graph (SCEG) is generated on the basis of an SCPL specification. Figure 5 illustrates the SCEG corresponding to the SCPL specification in Figure 4 . Formally an SCEG is a labelled DAG P =< N, A, spe > where N is a set of vertices, A is a set of arcs over N , such that – for every operand and label in a statement in SCPL, create a vertex; – for v ∈ V , spe(v) represents the type of composition and the mapping specification; – if u is used in v for composition, introduce an arc u → v.
