Space support in databases poses new challenges in every part of a database management system & the capability of spatial support in the physical layer is considered very important. This has led to the design of spatial access methods to enable the effective & efficient management of spatial objects.

R-trees have a simplicity of structure & together with their resemblance to the B-tree, allow developers to incorporate them easily into existing database management systems for the support of spatial query processing.

This book provides an extensive survey of the R-tree...

This book constitutes the refereed proceedings of the 10th East European Conference on Advances in Databases and Information Systems, ADBIS 2006. The book presents 29 high-quality papers selected in a rigorous reviewing process. The papers address a wide range of hot research issues and are organized in topical sections on: XML databases and semantic web, web information systems and middleware, query processing and indexing, modelling and design issues, and more.

This book contains the best papers of the 8th International Conference on Enterprise Information Systems (ICEIS 2006), held in the city of Paphos (Cyprus), organized by the Institute for Systems and Technologies of Information, Control and Communication (INSTICC) in collaboration with the University of Cyprus, Aristotle University of Thessaloniki and Athens University of Economics and Business. ICEIS has become a major point of contact between research scientists, engineers and practitioners in the area of business applications of information systems. This year, five simultaneous tracks were...
