System execution traces are useful artifacts for validating enterprise distributed software system quality-of-service (QoS) properties, such as end-to-end response time, service time, and throughput. With proper planning during development phase of the software lifecycle, it is possible to ensure such traces contain required properties to facilitate analysis for QoS validation. In some case, however, it is not possible to ensure system execution traces contain the necessary properties for QoS analysis. Consequently, this makes it hard to analyze such system execution traces for validation of QoS properties. this paper therefore presents preliminary work on the System Execution Trace Adaptation Framework (SETAF) for adapting system execution traces to support analysis of It also presents preliminary results from applying SETAF to externally developed applications. the initial results show that it is possible to validate QoS properties by adapting system execution traces at analysis time instead of modifying the application's existing source code.

this work investigates the use of knowledge about organizational roles captured in enterprise models for service configuration. Based on an industrial case, it presents a way to extract a role's information demand and to use this as initial configuration for agent-based services. In addition to the meta-model included in the enterprise modeling language, the use of a common ontology is proposed which captures both, the perspective of information demand and services. the architecture of the agent-based services is following the idea to characterize all enterprise members and components by their functions and to represent them by sets of services provided by them. the main contributions of the paper are (1) to show that a role's information demand is relevant for service configurayion, (2) to present a way of extracting information demand from enterprise models, and (3) to extend an approach for SOA-based enterprise representation with information demand.

It is crucial for enterprises to execute business operations in a compliant way. this is especially true for IT-driven business processes as enterprises may face considerable fines when violating laws and regulation in their business processes. through the advent of cloud computing, a new dimension of compliance requirements within the research area of compliant business process design has emerged. Data-sovereignty is one of the major compliance concerns enterprises have to deal with when moving applications and data to the cloud. enterprises are fully responsible for their data, also when the data is not present within their IT premises anymore. this lead to the policy that specific data must not leave the IT premises of the enterprise. In this paper we present an approach to support the human process designer in modelling compliant business processes. We are focusing on compliance requirements which have to be considered in the field of cloud computing. these requirements have been created to meet laws and regulations. these laws and regulations are considering data which is to other countries, for example. Looking at the characteristics of these requirements, we deal with data-centric compliance rules here.

Orthographic Service Modeling

international Workshop on enterprise distributed object computing, EDOCW

作者： Colin Atkinson Dietmar Stoll Christian Tunjic Software Engineering University of Mannheim Mannheim Germany

As the size and complexity of services has grown over the years, so has the number of different models and view types used to visualize them. However, in most development environments used today, views are usually organized in a fairly simple way within an arrangement of trees, and are often mixed arbitrarily with the artifacts they contain or visualize. In this position paper we propose a new paradigm for creating, organizing and managing the different views that are required in modern software development projects inspired by the orthographic projection paradigm that has been used for many years in other engineering disciplines. the approach therefore makes software engineering environments more like computer-aided design (CAD) tools for physical products. After explaining the basic idea behind the approach, which we refer to as Orthographic Service Modeling (OSM), we outline its three key ingredients - (1) on- demand view generation, (2) dimension-based navigation (3) and an inherently view-based method.

Automation Processes for enterprise Architecture Management

Automation Processes for Enterprise Architecture Management

Creating and maintaining an enterprise architecture model that is both up-to-date and accurate is a difficult task due to the size and complexity of the models and the dispersed nature of EA information in organizations. In current EA maintenance processes, the models are maintained manually with only little automation, which is a time consuming task. Literature from research and practice has identified this challenge, but only few scientific publications actually address the issue of EA model maintenance and its automation. In our research effort on Living Models, we are working towards solutions for a closer connection between EA models and what they represent in the real world. In this article we present (semi-)automated processes for maintaining enterprise architecture models by gathering information from both human input and technical interfaces and discuss implementation issues for realizing the processes in practice. this work is one of the first steps in the direction of minimizing manual work for EAM by automation and increasing EA data quality attributes such as consistency and actuality.

enterprise architecture (EA) management provides an engineering approach for the continuous advancement of the enterprise as a whole. the high number of involved components and their dense web of interdependencies nevertheless form a major challenge for such approach and demand high initial investment into documentations, communications, and analysis. Aforementioned fact has in the past been an impediment for successful EA management in practice. In the field of software engineering recently lightweight and agile methods have become more and more important. these methods aim at quickly creating results, while staying flexible in respect to the design goals to attain. In this article we explore to which extent the de-facto standard for agile methods, namely Scrum, can be applied to EA management. thereby, we derive challenges for an agile EA management approach and revisit current approaches regarding their agility. Finally, we outline how agile EA management can be implemented based on the method of Scrum.

the "Region Sans Film" ("Filmless Region") program was launched in 2009 by the French ministry of health in order to help the generalization to all healthcare structures such as hospitals or general physician practices, of Picture Archiving and Communication Systems (PACS), Radiological Information Systems (RIS) and archiving of medical images. It is done by means of a service platform whom building and running has been confided to an industrial consortium. this platform implements the latest technologies of medical image processing and of cloud computing. It is built in order to support service-oriented enterprise architecture composed of one main layer of software services. It is innovative because it is the first one which contains all the materials for the implementation of all services in the cloud, allowing for each healthcare structure to open these services beyond its borders. this opens new opportunities for the implementation of new business processes/services around sharing of images such as teleradiology or access to the images produced in hospitals to the general practitioners. By these means, the exercise of real film less radiology can be more widely achieved.

Standardization is an important aspect of building interoperable service-oriented e-Business solutions. XML-based standards have become increasingly popular to address some of the interoperability challenges, both in commercial and governmental organizations. However, the number of available XML-based standards has created a situation, where users have difficulties in choosing the most suitable standard, or are forced to support multiple standards at the same time. therefore, it is important to provide tools for analyzing and comparing different standards. Existing qualitative studies have created tools that can highlight general features by manual analysis. However, in this paper, we argue that additional insights could be obtained by extracting relevant quantitative metrics of the actual XML Schema documents that the standards contain. this study analyzes three prominent e-Business document standards in terms of their quantitative metrics. Based on our results we claim that quantitative studies can enhance the use of the qualitative analysis frameworks and bring attention to useful details when comparing different standards.

Local governments cover multiple service sectors and are typically organized into diversified, deeply hierarchical organizations. Public services offered are tangible, mostly non-IT-critical, and heavily dependent on human resources. Information management is mainly manual in strategy and management processes. In this case study of a large Finnish local government organization, enterprise architecture (EA) is proposed as a tool for improving the coherency of the local government and its alignment to IT and other resources. We ask, what kind of EA descriptions local government agencies need for coherency management, and how to organize them. We apply action design research principles at the Kouvola City concern by adapting the Finnish Government EA Grid there. the business architecture is unfolded to evaluate the target state for a planned change. the results give new insights into transformation of the local government towards new public management related operation models, government-IT alignment, and further development of EA description tools and repositories for public administration use.
