th This volume contains papers presented during 13 International Conference on Inf- mation Systems Development - Advances in Theory, Practice and Education (ISD'2004), held in Vilnius, Lithuania, September 9-11, 2004. The intended audience for this book comprises researchers and practitioners interested in current trends in the InformationS- tems Development (ISD) ?eld. Papers cover a wide range of topics: ISD methodologies, methodengineering,businessandISmodelling,websystemsengineering,databaserelated issues, informationanalysisanddatamining,qualityassessment, costingmethods,security issues, impact of organizational environment, and motivation and job satisfaction among IS developers. The selection of papers was carried out by the International Program C- mittee. All papers were reviewed in advance by three reviewers and evaluated according to their relevance, originality and presentation quality. Papers were evaluated only on their own merits, independent of other submissions. Out of 117 submissions Program Comm- tee selected 75 research papers to be presented at the Conference. 39 best papers and 5 papers presented by invited speakers are published in this volume. th The13 InternationalConferenceonInformationSystemsDevelopmentcontinuesthe tradition started with the ?rst Polish-Scandinavian Seminar on Current Trends in Infor- tion Systems Development Methodologies, held in Gdansk, Poland in 1988. Through the years this seminar has evolved into one of most prestigious conferences in the ?eld. ISD Conferenceprovidesan internationalforumfor the exchangeof ideasbetween the research community and practitioners and offers a venue where ISD related educational issues are discussed. ISD progresses rapidly, continually creating new challenges for the professionals - volved. New concepts and approaches emerge in research as well as in practice.

The importance of databases and information systems to the functioning of 21st century life is indisputable.This book presents papers from the 13th International Baltic Conference on Databases and Information Systems, held in Trakai, Lithuania, from 1- 4 July 2018. Since the first of these events in 1994, the Baltic DB&IS has proved itself to be an excellent forum for researchers, practitioners and PhD students to deliver and share their research in the field of advanced information systems, databases and related areas. For the 2018 conference, 69 submissions were received from 15 countries. Each paper was assigned for review to at least three referees from different countries. Following review, 24 regular papers were accepted for presentation at the conference, and from these presented papers the 14 best-revised papers have been selected for publication in this volume, together with a preface and three invited papers written by leading experts. The selected revised and extended papers present original research results in a number of subject areas: information systems, requirements and ontology engineering; advanced database systems; internet of things; big data analysis; cognitive computing; and applications and case studies. These results will contribute to the further development of this fast-growing field, and will be of interest to all those working with advanced information systems, databases and related areas.

This book constitutes the refereed proceedings of the 13th International Baltic Conference on Databases and Information Systems, DB&IS 2018, held in Trakai, Lithuania, in July 2018.The 24 revised papers presented were carefully reviewed and selected from 69 submissions. The papers are centered around topics like information systems engineering, enterprise information systems, business process management, knowledge representation, ontology engineering, systems security, information systems applications, database systems, machine learning, big data analysis, big data processing, cognitive computing.
