As enterprises merge, split up, or grow, existing legacy systems from different vendors implemented in different programming languages and running in different environments as well as roll-your-own applications have to be integrated. Furthermore, companies are starting to shift more and more on-premise software to software run in aSoftware as a Service (SaaS) business model. Outsourcing software to external and internal SaaS providers introduces new integration challenges, namely those of the integration of standard SaaS software with on-premise systems or other systems run at different SaaS providers which is a problem not addressed by SaaS platforms today. Recurring integration problems can be described by means of Enterprise Application Integration patterns. Those are used as nuggets of advice to solve complex integration problems. In this paper, we introduce executable EAI patterns offered in a SaaS business model to allow companies to focus on the integration without the need for the setup of complex integration infrastructures. Users will be guided by workflows customizing configurable EAI patterns to easily create integration solutions. We therefore propose EAI as a Service as a flexible, customizable, inexpensive way to tackle EAI problems both of on-premise systems but also of systems run in a SaaS business model.","PeriodicalId":210496,"journal":{"name":"2008 12th International IEEE Enterprise Distributed Object Computing Conference","volume":"49 15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133631858","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}

Many EIS apply role-based access control (RBAC) mechanisms to specify access rules based on organizational models. However, only little research has been spent on organizational changes even though they often become necessary in practice. Examples comprise the evolution of organizational models with subsequent adaptation of access rules or direct access rule modifications. In this paper, we present a change framework for the controlled evolution of access rules in EIS. Specifically, we define change operations which ensure correct modification of access rules. Finally, we define the formal semantics of access rule changes based on operator trees which enables their unambiguous application; i.e., we can precisely determine which effects are caused by respective adaptations. This is important, for example, to be able to efficiently adapt user worklists in process-aware information systems. Altogether this paper contributes to comprehensive life cycle support for access rules in (adaptive) EIS.","PeriodicalId":210496,"journal":{"name":"2008 12th International IEEE Enterprise Distributed Object Computing Conference","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130745791","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}

Capra","doi":"10.1109/EDOC.2008.10","DOIUrl":"https://doi.org/10.1109/EDOC.2008.10","url":null,"abstract":"Service providers as we know them nowadays are the always-on static web service providers, that aim at Five9 availability (99.999%). Formal, or de-facto, standards, such as WSDL and BPEL, have become technology enablers for the easy discovery, use and coordination of such services. However, we envisage tomorrow's services to become increasingly pervasive, being deployed within buildings, transport systems, markets, as well as people portable devices. Such services will be, by their own nature, simple and fine grained; as a consequence, service composition will become crucial to deliver rich functionalities that satisfy end-users requests. Composing services in mob.ile environments opens up significant challenges. In particular, the Five9 availability assumption no longer holds: the higher the dynamic nature of the environment, the higher the chances that services will move out-of-reach before the composition completes, causing the service as a whole to fail. We argue that, in order to enable the successful completion of compound services, the reliability of the composition must be measured and reasoned about. In order to do so, we propose to dynamically deploy a prediction model to estimate the duration of colocation between componentservices. These estimates are fed in input to a service composition semantics reasoner, which then autonomically selects those providers, within the current environment, that maximise the chances of successful compound service completion. We demonstrate the positive impact that the reliability reasoning has onto the ratio of successfully completed compound services in a typical human movement scenario.","PeriodicalId":210496,"journal":{"name":"2008 12th International IEEE Enterprise Distributed Object Computing Conference","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115748959","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}

These properties are referred as quality of service (QoS). Failing to accurately specify and communicate quality details can lead to wrong and inconsistent expectations held by the service provider and service consumer and result in serious disagreement. Popular Web service description development and management solutions, e.g. WS-Policy and Web Service Level Agreement, do not properly cater for the specification and negotiation of quality related requirements for collaborative services. In this paper we present a comprehensive mechanism for the specification of quality requirements. The proposed approach allows service providers and consumers to explicitly define and adjust both higher level and concrete measurement requirements for quality of a service in a formally verifiable manner. As a result, quality negotiations can be performed effectively for the establishment of service provision agreements.","PeriodicalId":210496,"journal":{"name":"2008 12th International IEEE Enterprise Distributed Object Computing Conference","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130376024","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}

The EAM Pattern Catalog, presented in this article, is a collection of best practices for addressing specific concerns in EA management related to e.g. architectural standardization, application landscape planning, or interface, business object, and service management. It provides methodologies for addressing these concerns, together with information models defining the relevant concepts, and viewpoints for visualizing them. This article describes the structure and extent of the EAM Pattern Catalog, and exemplifies its approach by outlining EAM patterns for addressing architectural standardization. Architectural standardization tries to tackle the complexity of the EA created by historically grown structures. These structures lead to disadvantages as low maintainability, low bargaining power at IT suppliers, or the need of largely diverse skills in the IT workforce.","PeriodicalId":210496,"journal":{"name":"2008 12th International IEEE Enterprise Distributed Object Computing Conference","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115133233","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}
