The LNCS journal Transactions on Large-Scale Data- and
Knowledge-Centered Systems focuses on data management, knowledge
discovery, and knowledge processing, which are core and hot topics in
computer science. Since the 1990s, the Internet has become the main
driving force behind application development in all domains. An increase
in the demand for resource sharing (e.g., computing resources, services,
metadata, data sources) across different sites connected through
networks has led to an evolution of data- and knowledge management
systems from centralized systems to decentralized systems enabling
large-scale distributed applications providing high scalability.
This, the 48th issue of Transactions on Large-Scale Data- and
Knowledge-Centered Systems, contains 8 invited papers dedicated to the
memory of Prof. Dr. Roland Wagner. The topics covered include
distributed database systems, NewSQL, scalable transaction management,
strong consistency, caches, data warehouse, ETL, reinforcement learning,
stochastic approximation, multi-agent systems, ontology, model-driven
development, organisational modelling, digital government, new
institutional economics and data governance.
