A summary of research carried out in the CHOROCHRONOS Project, established as an EC-funded Training and Mobility Research Network with the objective of studying the design, implementation, and application of spatio-temporal database management systems. The nine coherent chapters by leading research groups are written in a tutorial style, making the research contributions of the project accessible to a wider audience interested in spatio-temporal information processing. Following an introductory overview, the book presents chapters on ontologies for spatio-temporal databases, conceptual models, spatio-temporal models and languages, access methods and query processing, architectures and implementation of spatio-temporal DBMS, interactive spatio-temporal documents, and future perspectives.

This book constitutes the refereed proceedings of the 8th International Conference on Extending Database Technology, EDBT 2002, held in Prague, Czech Republic, in March 2002.The 36 revised full papers presented together with six industrial and application papers, 13 software demos and one invited paper were carefully reviewed and selected from a total of 207 submissions. The papers are organized in topical sections on query transformation, data mining, XML, advanced query processing, moving objects, distributed data, distributed processing, advanced querying, XML-advanced querying, fundamental query services, estimation/histograms, and aggregation.

This book constitutes the refereed proceedings of the 7th International Conference on Spatial and Temporal Databases, SSTD 2001, held in Redondo Beach, CA, USA, in July 2001.The 25 revised full papers and two industrial papers presented were carefully reviewed and selected from a total of 70 submissions. The book offers topical sections on modeling and querying, moving-object query processing, query processing: architectures and cost estimation, processing advanced queries, formal aspects, data representation, industrial session, data warehousing and mining, and indexing.

The 1999 Workshop on Spatio-Temporal Database Management, held in Ed- burgh, Scotland, September 10 11, 1999, brought together leading researchers anddevelopersintheareaofspatio-temporaldatabasestodiscussthestate-- the-art in spatio-temporal research and applications and to understand the new challenges and future research directions in this emerging and rapidly advancing area. The workshop served as a forum for disseminating research and expe- ence in spatio-temporal databases and for maximizing interchange of knowledge among researchers from the established spatial and temporal database com- nities.Theexchangeofresearchideasandresultsnotonlycontributestothe academic arena, but also bene?ts the user and commercial communities. Theseproceedingscontainthe researchpapersselectedforpresentationatthe workshop. The workshop was conceived from the outset to have a general scope within its areaand to be internationalin participation.The callfor papers aimed to attract the highest quality and most up-to-date research contributions from around the world, and the workshop was co-located with VLDB 99, enabling many participants to conveniently attend both events and thereby facilitating the widest possible international participation. The call for papers attracted 30 research papers, which were submitted by authors from 14 countries and ?ve continents, clearly indicating the truly int- nationalnatureoftheemergingareaofspatio-temporaldatabases.Aprogram committee consisting of 25 researchers from four continents conducted four - viewsofeachpaperandselected13outstandingpapersofrpresentationand discussion at the workshop and inclusion in the proceedings.

The three-volume set LNCS 12681-12683 constitutes the proceedings of the 26th International Conference on Database Systems for Advanced Applications, DASFAA 2021, held in Taipei, Taiwan, in April 2021. The total of 156 papers presented in this three-volume set was carefully reviewed and selected from 490 submissions. The topic areas for the selected papers include information retrieval, search and recommendation techniques; RDF, knowledge graphs, semantic web, and knowledge management; and spatial, temporal, sequence, and streaming data management, while the dominant keywords are network, recommendation, graph, learning, and model. These topic areas and keywords shed the light on the direction where the research in DASFAA is moving towards. Due to the Corona pandemic this event was held virtually.
