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 paper intoduces the Scalable INcremental hash-based Algorithm (SINA, for short); a
new algorithm for evaluting a set of concurrent continuous spatio-temporal queries. SINA is …

A number of emerging applications of data management technology involve the monitoring
and querying of large quantities of continuous variables, eg, the positions of mobile service …

Location-aware environments are characterized by a large number of objects and a large
number of continuous queries. Both the objects and continuous queries may change their …

The rapid increase in spatio-temporal applications calls for new auxiliary indexing
structures. A typical spatio-temporal application is one that tracks the behavior of moving …

Publisher Summary This paper proposes a generalized bottom-up update strategy for R-
trees. This strategy is motivated by the class of monitoring applications, which are …

Moving object databases are required to support queries on a large number of continuously
moving objects. A key requirement for indexing methods in this domain is to efficiently …
