Index structures are designed to optimize search performance, while at the same time supporting efficient data updates. Although not explicit, existing index structures are typica...
Spatio-temporal databases deal with geometries changing over time. In general, geometries do not only change discretely but continuously; hence we are dealing with moving objects....
Abstract. Multidimensional databases are large collections of data, often historical, used for sophisticated analysis oriented to decision making. This activity is supported by an ...
Querying non-conventional data is recognized as a major issue in new environments and applications such as those occurring in pervasive computing. A key issue is the ability to qu...
Moving objects are currently represented in databases by means of an explicit representation of their trajectory. However from a physical point of view, or more specifically accor...
