An approach for the Development of adaptable Services-oriented Systems

Software engineering is marked by the emergency of two paradigms: SOC (Service Oriented Computing) and CAC (Context-Aware Computing). While SOC paradigm aims to deal in the problem of interoperability, the CAC paradigm main’s target is to challenge the adaptability of IS contexts. The adoption of these two paradigms raised the challenge of the development process of Services Oriented Systems (SOS) adaptable to the context. The purpose of this paper is to propose a model driven the development process of Services-Oriented Systems adaptable to users’ context

A Model-Driven Approach for Monitoring Business Performance in Web Service Compositions

Abstract — Supporting business services through Web service compositions (WSC) as part of service-oriented architectures (SOA) involves business performance monitoring requirements. Their implementation results in additional development activities. To support these activities, we already contributed a model-driven approach to the development of monitored WSC as part of our preliminary work. In this paper, we present an extension to this approach, which focuses on supporting the specification and transformation of indicators to an executable implementation. To reduce development effort for this particular task, we provide a template-based mechanism for defining performance indicators. In combination with our preliminary work, now fully monitored WSC can be generated automatically from platformindependent design models. We demonstrate the applicability of the overall approach by instantiating an integrated development process for a target platform based on IBM SOA products and showing its application for a sample business process along with monitoring requirements

Development of service-oriented architectures using model-driven development : a mapping study

Context: Model-Driven Development (MDD) and Service-Oriented Architecture (SOA) are two challenging research areas in software engineering. MDD is about improving software development whilst SOA is a service-based conceptual development style, therefore investigating the available proposals in the literature to use MDD when developing SOA may be insightful. However, no studies have been found with this purpose. Objective: This work aims at assessing the state of the art in MDD for SOA systems. It mainly focuses on: what are the characteristics of MDD approaches that support SOA; what types of SOA are supported; how do they handle non-functional requirements. Method: We conducted a mapping study following a rigorous protocol. We identified the representative set of venues that should be included in the study. We applied a search string over the set of selected venues. As result, 129 papers were selected and analysed (both frequency analysis and correlation analysis) with respect to the defined classification criteria derived from the research questions. Threats to validity were identified and mitigated whenever possible. Results: The analysis allows us to answer the research questions. We highlight: (1) predominance of papers from Europe and written by researchers only; (2) predominance of top-down transformation in software development activities; (3) inexistence of consolidated methods; (4) significant percentage of works without tool support; (5) SOA systems and service compositions more targeted than single services and SOA enterprise systems; (6) limited use of metamodels; (7) very limited use of NFRs; and (8) limited application in real cases. Conclusion: This mapping study does not just provide the state of the art in the topic, but also identifies several issues that deserve investigation in the future, for instance the need of methods for activities other than software development (e.g., migration) or the need of conducting more real case studies.Peer ReviewedPostprint (author's final draft

Modellgetriebene Entwicklung überwachter Webservice-Kompositionen

Ziel der Arbeit ist es, existierende Ansätze für die Entwicklung von WS-Kompositionen dahingehend zu ergänzen, dass die Überwachungsbelange zielgerichtet und effizient berücksichtigt werden können. Die Prinzipien der modellgetriebenen Softwareentwicklung werden dazu genutzt, um (1) eine plattformunabhängige Spezifikation der Belange und (2) eine vollständig automatisierte Überführung dieser Spezifikation in lauffähige Implementierungen zu ermöglichen

Benutzerinteraktion in dienstorientierten Architekturen

Ziel der Arbeit ist es, im Rahmen bestehender Entwicklungsvorgehen zur dienstorientierten Unterstützung von Geschäftsprozessen die Anforderungen des Menschen als Benutzer der IT von der Analyse bis zur Implementierung integriert berücksichtigen zu können. Hierbei kommen die Prinzipien der modellgetriebenen Softwareentwicklung zum Einsatz, um (1) eine plattformunabhängige Spezifikation dieser Anforderungen und (2) eine automatisierte Erzeugung der entsprechenden Softwareartefakte zu ermöglichen

An evaluation of the challenges of Multilingualism in Data Warehouse development

In this paper we discuss Business Intelligence and define what is meant by support for Multilingualism in a Business Intelligence reporting context. We identify support for Multilingualism as a challenging issue which has implications for data warehouse design and reporting performance. Data warehouses are a core component of most Business Intelligence systems and the star schema is the approach most widely used to develop data warehouses and dimensional Data Marts. We discuss the way in which Multilingualism can be supported in the Star Schema and identify that current approaches have serious limitations which include data redundancy and data manipulation, performance and maintenance issues. We propose a new approach to enable the optimal application of multilingualism in Business Intelligence. The proposed approach was found to produce satisfactory results when used in a proof-of-concept environment. Future work will include testing the approach in an enterprise environmen
