This volume results from the four-day scientific Second International East/West Database Workshop which took place 25th-28th September 1994, in Klagenfurt, Austria, continuing a series of workshops started in Kiev in 1990 (Lecture Notes in Computer Science No. 504, Springer, "Next Generation Information System Technology"). The aims of this workshop are twofold: first, to provide a forum for the presentation and in-depth discussion of scientific achievements in the field of advanced databases that will effectively improve the building and use of future information systems; second, to establish and increase communication between research communities which were formerly separated and, therefore, had only rare opportunities to interact. It should establish contacts between researchers from the East and from the West to make exchange of ideas possible and to trigger collaborations. However, it is not only political borders which change their perviousness as a result of -or giving rise to -new autonomies or new possibilities for interaction and collaboration. The same happens with the borders between scientific areas, in particular in the dynamically evolving areas of computer science. Databases and programming languages are integrated in object oriented databases, database and information retrieval technology form together the basis for modern (multimedia) information systems. Furthermore, the borders between different information systems change and allow various forms of collaboration while maintaining different degrees of autonomy. Heterogeneous and distributed databases are enabling technologies for these systems.

This book is a comprehensive presentation of entity-relationship (ER) modeling with regard to an integrated development and modeling of database applications. It comprehensively surveys the achievements of research in this field and deals with the ER model and its extensions. In addition, the book presents techniques for the translation of the ER model into classical database models and languages, such as relational, hierarchical, and network models and languages, as well as into object-oriented models.

This book constitutes the refereed proceedings of the 9th East European Conference on Advances in Databases and Information Systems, ADBIS 2005, held in Tallinn, Estonia, in September 2005. The 27 revised full papers presented together with an invited paper were carefully reviewed and selected from 144 submissions. The papers are organized in topical sections on database theory, database modelling and physical database design, query processing, heterogeneous databases and interoperability, XML and databases, data mining and knowledge discovery, information systems and software engineering, and information systems development.

This book constitutes the joint refereed proceedings of nine international workshops held as part of OTM 2005 in Agia Napa, Cyprus in October/November 2005.The 145 revised full papers presented were carefully reviewed and selected from a total of 268 submissions. Topics addressed are agents, Web services and ontologies merging (AWeSOMe 2005), context-aware mobile systems (CAMS 2005), grid computing and its application to data analysis (GADA 2005), inter-organizational systems and interoperability of enterprise software and applications (MIOS+INTEROP 2005), object-role modeling (ORM 2005), a PHD symposium (PhDS 2005), semantic-based geographical information systems (SeBGIS 2005), Web semantics (SWWS 2005), and ontologies, semantics and e-learning (WOSE 2005).

This book presents a framework for developing as well as a comprehensive collection of state-of-the-art process querying methods. Process querying combines concepts from Big Data and Process Modeling and Analysis with Business Process Intelligence and Process Analytics to study techniques for retrieving and manipulating models of real-world and envisioned processes to organize and extract process-related information for subsequent systematic use. The book comprises sixteen contributed chapters distributed over four parts and two auxiliary chapters. The auxiliary chapters by the editor provide an introduction to the area of process querying and a summary of the presented methods, techniques, and applications for process querying. The introductory chapter also examines a process querying framework. The contributed chapters present various process querying methods, including discussions on how they instantiate the framework components, thus supporting the comparison of the methods. The four parts are due to the distinctive features of the methods they include. The first three are devoted to querying event logs generated by IT-systems that support business processes at organizations, querying process designs captured in process models, and methods that address querying both event logs and process models. The methods in these three parts usually define a language for specifying process queries. The fourth part discusses methods that operate over inputs other than event logs and process models, e.g., streams of process events, or do not develop dedicated languages for specifying queries, e.g., methods for assessing process model similarity. This book is mainly intended for researchers. All the chapters in this book are contributed by active researchers in the research disciplines of business process management, process mining, and process querying. They describe state-of-the-art methods for process querying, discuss use cases of process querying, and suggest directions for future work for advancing the field. Yet, also other groups like business or data scientists and other professionals, lecturers, graduate students, and tool vendors will find relevant information for their distinctive needs.

This volume includes very high quality papers in different areas of computer and information sciences. The main themes are (computer network) performance evaluation and artificial neural networks and their applications. The latest developments in these areas are presented by a number of distinguished researchers from all over the world. These proceedings of The 13th International Symposium on Computer and Information Sciences (ISCIS'98) contain outstanding papers specifically related to the areas of "Gelenbe" neural networks and their applications, performance of computer-communication networks, simulations and analytic methods in order to study the performance of telecommunication networks, scheduling and resource allocation in computer and multimedia systems, stochastic ordering applied to performance evaluation, and simulation of virtual humans.

This book constitutes the thoroughly refereed post-workshop proceedings of the 6th International Workshop on Database Programming Languages, DBPL-6, held in Estes Park, Colorado, USA, in August 1997. The 20 revised full papers presented have gone through two rounds of reviewing and selection. Also included are two invited talks, the transcription of a panel discussion and an introductory survey by the volume editors. The papers address all current aspects of database programming languages, in particular spatial databases, typing, query languages for new applications, views, expressive power, aggregate queries, cooperative work, and transactions.
