Boosting location-based services with a moving object database engine

Composition of temporal and spatial properties of real world objects in a unified data framework results into Moving Object Databases (MOD). MODs are able to process, manage and analyze discretely or continuously changing spatio-temporal data. This paper presents HERMES Moving Data Cartridge, which provides MOD functionality to OpenGIS-compatible state-of-theart Object-Relational DBMS. HERMES is designed to be used as a pure temporal or a pure spatial system, however, its main application is to support modeling and querying of moving A relevant collection of abstract data types (ADT) and their corresponding operations are defined, developed and provided as a data cartridge extending SQL-like query languages with MOD semantics. The usefuleness of the resulting query language is demonstrated by developing an application on top of this framework, which builds and visualizes the results of a palette of spatio-temporal queries that have been proposed in the literature as an advanced Locati...
