Integration ist eine wichtige Anforderung an Entwurf und Implementierung betrieblicher Informationssysteme. Am Markt gibt es ein breites Spektrum an anspruchsvollen, oft noch imWandel begriffenen Werkzeugen und Technologien (z.B. ETL, Application Server, Web Services, EAI, WfMS, SOA) mit zum Teil ähnlicher Funktionalität zur Lösung der Integrationsaufgaben. Die spezifische Auswahl eines geeigne...

In this paper we present LeXFlow, a web application framework where lexicons already expressed in standardised format semiautomatically interact by reciprocally enriching themselves. LeXFlow is intended for, on the one hand, paving the way to the development of dynamic multi-source lexicons; and on the other, for fostering the adoption of standards. Borrowing from techniques used in the domain ...

There is a wide range of scientific application domains requiring sophisticated management of spatio-temporal data. However, existing database management systems offer very limited (if any at all) support for managing such data. Thus, it is left to the researchers themselves to repeatedly code this management into each application. Besides being a time consuming task, this process is bound to i...

The Extensible Problem-Specific Tutor (xPST) system was created to facilitate the creation of intelligent tutoring systems (ITSs) on existing software and web-based interfaces. This research introduces xPST and describes an exploration of the ease of authoring an xPST tutor for three web-based tasks. Participants demonstrated a quick learning curve and alternated their attentional focus regular...

In recent years, numerous vehicular technologies, e.g., cruise control and steering assistant, have been proposed and deployed to improve the driving experience, passenger safety, and vehicle performance. Despite the existence of several novel vehicular applications in the literature, there still exists a signi€cant gap between resources needed for a variety of vehicular (in particular, data-do...

This work proposes a XML-based framework for distributing and enforcing RSVP access control policies, for RSVP-aware application servers. Policies are represented by extending XACML, the general purpose access control language proposed by OASIS. Because RSVP is a specific application domain, it is not directly supported by the XACML standard. Hence, this work defines the XACML extensions requir...

The Tools and Materials Metaphor is a design methodology for interactive software systems. It supports developers with both metaphors on how to interpret and understand an application domain as well as concrete techniques on how to actually construct systems according to the metaphors. The construction process is best supported by an application framework that captures those parts of the metaph...

A possible measure of quality for any model or methodology is the degree of acceptance and usage. This paper discusses the factors that contribute to the industrial acceptability of conceptual models for web application design. We present an empirical study that examined 62 companies or institutions (in America and Europe) involved in large-scale web application development. By investigating th...

With the rise of Model Driven Engineering (MDE) as a software development methodology, which increases productivity and, supported by powerful code generation tools, allows a less error-prone implementation process, the idea of modeling security aspects during the design phase of the software development process was first suggested by the research community almost a decade ago. While various ap...

This paper discusses a trade-off strategy for small projects and presents a preliminary guidelines for assessing the appropriateness of a trade-off. The motivation of this work is to make the development team aware of the performed trade-offs and to see both the associated opportunities and risks, to assess the appropriateness of a trade-off and to gather information for the future development ...
