Welcome to Hermes Moving Object Database Homepage
______________________________________________________________________________________________________

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. HERMES 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 objects. 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.
