Supporting TDD can be difficult when building Service-Oriented Architecture (SOA) applications, since standard test frameworks often do not have capabilities for performing and validating Web service (WS) calls; invoking Web services depends on running and connecting to a service container; and services and clients often have entirely separate implementations. In this paper we present case studies of two SOA applications we developed, GRIDL[i] and TxFlow. These are distributed, multi-language applications using Web services as the interface between service and client components. They implement Web service and client tests both for verification and validation of the application components and to facilitate the TDD process. Our approach to Web service testing to support TDD is easily reproducible in any SOA application without requiring significant development effort or changes to the software design.","PeriodicalId":159235,"journal":{"name":"2009 Congress on Services - I","volume":"143 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114909443","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While various schemes have been proposed for fault tolerant MAS, the replication approach provides the basis of short recovery latency, less intrusive with respect to the execution time, and high scalability. In this paper we propose a new replication scheme making a decision on either replicating data or replacing the failed agent according to the current status of the agents. It thus greatly reduces the overhead of the fault tolerance mechanism by minimizing the amount of replication of the agents. The effectiveness of the proposed approach is verified using the agent-based hospital information provisioning system implemented on the agent platform developed by the authors. The experiment displays that the proposed approach significantly outperforms the existing approach in terms of recovery latency.","PeriodicalId":159235,"journal":{"name":"2009 Congress on Services - I","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114444512","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, conventional choreography descriptions provide only a partial view of the interaction. They do not capture critical business-domain knowledge including: goals motivating participants to interact, organizational dependencies that enable the interaction, and physical activities that are part of the interaction contract. In the absence of this knowledge, it is hard to argue if a choreography description satisfies the business goals of participants. This deficiency is critical when the need arises to adapt the choreography to changes in business requirements. In this paper, we argue for representing choreography at the level of requirements motivating the interaction. To bridge the two worlds of choreographed messaging and requirements, we propose an automated technique for deriving choreography descriptions. Utilizing the precise semantics offered by requirements models we infer constraints on the choreographed messaging, from which we generate a choreography description that satisfies the requirements.","PeriodicalId":159235,"journal":{"name":"2009 Congress on Services - I","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114550603","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They can systematically collect provenance information for the derived data products to be later queried. Despite the efforts on building a standard Open Provenance Model (OPM), provenance is tightly coupled to SWfMS. Thus scientific workflow provenance concepts, representation and mechanisms are very heterogeneous, difficult to integrate and dependent on the SWfMS. To help comparing, integrating and analyzing scientific workflow provenance, this paper presents a taxonomy about provenance characteristics. Its classification enables computer scientists to distinguish between different perspectives of provenance and guide to a better understanding of provenance data in general. The analysis of existing approaches will assist us in managing provenance data from distributed heterogeneous workflow executions.","PeriodicalId":159235,"journal":{"name":"2009 Congress on Services - I","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114846298","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Laboratory Information Management Systems (LIMS) coordinate the management of wet lab tasks, samples, and instruments and allow reasoning on business-like parameters such as ordering (e.g., invoicing) and organization (automation and optimization) whereas workflow systems support the design of workflows in-silico for their execution. We present an approach that supports reasoning on scientific workflows that mix wet and digital tasks. Indeed, experiments are often first designed and simulated with digital resources in order to predict the quality of the result or to identify the parameters suitable for the expected outcome. ProtocolDB allows the design of scientific workflows that may combine wet and digital tasks and provides the framework for prediction and reasoning on performance, quality, and cost.","PeriodicalId":159235,"journal":{"name":"2009 Congress on Services - I","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134220152","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In a cloud, each service in an application is deployed as one or more service instances. Different service instances operate at different quality of service (QoS) levels. In order to satisfy given service level agreements (SLAs) as end-to-end QoS requirements of an application, the application is required to optimize its deployment configuration of service instances. $E^3/Q$ is a multiobjective genetic algorithm to solve this problem. By leveraging queuing theory, $E^3/Q$ estimates the performance of an application and allows for defining SLAs in a probabilistic manner. Simulation results demonstrate that $E^3/Q$ efficiently obtains deployment configurations that satisfy given SLAs.","PeriodicalId":159235,"journal":{"name":"2009 Congress on Services - I","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124451445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
