This book constitutes extended, revised and selected papers from the 22nd International Conference on Enterprise Information Systems, ICEIS 2020, held online during May 5-7, 2020.The 41 papers presented in this volume were carefully reviewed and selected for inclusion in this book from a total of 255 submissions. They were organized in topical sections as follows: database and information systems integration; artificial intelligence and decision support systems; information systems analysis and specification; software agents and internet computing; human-computer interaction; and enterprise architecture.

This book presents the refereed proceedings of the Second International Workshop on Constraint Database Systems, CDB '97, held in Delphi, Greece, in January 1997 together with some papers presented at the CP '96 Workshop on Constraints and Databases, held in Cambridge, Massachussetts, in August 1996.
The 18 revised full papers presented were carefully reviewed and selected for inclusion in the volume; also included are the extended abstract of an invited contribution and two survey papers. The papers are organized in sections on languages, expressiveness of spatial languages, systems, temporal applications, new applications, indexing, constraint programming, and optimization.

This book constitutes the refereed post-conference proceedings of the 24th International Conference on Enterprise Information Systems, ICEIS 2022, This conference was held virtually due to the COVID-19 crisis, during April 25-27, 2022. The 20 full papers included in this book were carefully reviewed and selected from 197 submissions. They were organized in topical sections as follows: Databases and Information Systems Integration; Artificial Intelligence and Decision Support Systems; Information Systems Analysis and Specification; Human-Computer Interaction; and Enterprise Architecture.

This book contains extended, revised and selected papers from the 23rd International Conference on Enterprise Information Systems, ICEIS 2021, held online during April 2021. The 26 papers presented in this volume were carefully reviewed and selected for inclusion from a total of 241 submissions. They are grouped in sections on databases and information systems integration, artificial intelligence and decision support systems, information systems analysis and specification, software agents and internet computing, human-computer interaction, and enterprise architecture.

Duale Studiengange kombinieren das Lernen an den Lernorten Hochschule und Praxis. Die Beliebtheit dualer Studienprogramme stieg in den vergangenen Jahren sukzessive an und ein Abflachen dieses Trends ist derzeit nicht erkennbar. Doch insbesondere zu den Lernprozessen am Arbeitsplatz sowie zu den Wirkungen der Praxisphasen ist forschungsseitig bislang wenig bekannt. An diesen Forschungsdesiderata setzt die vorliegende Monografie an: In einem Forschungsprojekt zwischen der Hochschule der Bundesagentur fur Arbeit (HdBA) und der Universitat Mannheim werden zwei Bachelorprogramme der HdBA in einem langsschnittlichen Forschungsdesign begleitet, um mehr uber die Praxisphasen der Studierenden zu erfahren. Neben der Analyse verschiedener Merkmale der Lern- und Arbeitstatigkeiten liegt ein zentraler Fokus in dieser Arbeit auf der Untersuchung potenzieller Einflussfaktoren der Kompetenzentwicklung. Dabei werden einerseits die Haufigkeiten verschiedener Lern- und Arbeitstatigkeiten, andererseits diverse Merkmale der Lern- und Arbeitsbedingungen berucksichtigt. Die Befunde der Untersuchung dienen als Grundlage der abgeleiteten Implikationen und Empfehlungen fur die Gestaltung von Praxisphasen in dualen Studiengangen.
