The family of languages that builds the foundation of the MEMO method is intended to feature a high degree of inter-language integration. For this purpose, the languages need to share common concepts. In order to define concepts that are semantically equivalent, it is recommendable to use the...

In this report a system for computer aided assessments and exercises on Java programming is presented and discussed. The report includes a detailed system description, experiences and evaluations from using the system, plans for future development and a brief overview about related work and...

In recent years, the development of domain-specific modelling languages has gained remarkable attention. This is for good reasons: A domain-specific modelling language incorporates concepts that represent domain-level knowledge. Hence, systems analysts are not forced to reconstruct these...

Das Handbuch erläutert und beschreibt die Linked-Employer-Employee-Daten des IAB, wie sie über das Forschungsdatenzentrum (FDZ) der Bundesagentur für Arbeit (BA) im IAB für wissenschaftliche Auswertungen externen Forschern und Forscherinnen zur Verfügung stehen. Es handelt sich dabei um auf...

Statistical research has always been at the edge of available computing power. Huge datasets, e.g in DataMining or Quantitative Finance, and computationally intensive techniques, e.g. bootstrap methods, always require a little bit more computing power than is currently available. But the most...

Automated use of electronic services calls for comprehensive service description languages.A couple of description languages have been developed so far each with a specific focus. Wedistinguish three different layers, syntactic, semantic, and resource description languages.In this paper we...

In diesem ersten Teil einer Reihe von Arbeitspapieren werden Grundbegriffeder Typtheorie (Datentyp, Typkompatibilität, Typsystem) vonProgrammiersprachen eingeführt. Es wird eine Klassifizierung vonTypsystemen vorgenommen.[...]

Unter modellgetriebener Software Entwicklung (sieheMDSD (Bettin, 2004), (Stahl u. a., 2006))werden Vorgehensmodelle verstanden, bei denen Software nicht primär in einer universellen Programmiersprachewie Java, C++, C# oder Smalltalk entwickelt wird, sondern bei der...
