The Nested List Normal Form is proposed as a syntactic normal form for semantically well-designed database schemata obtained from any arbitrary finite nesting of records and lists....
This paper presents the Scalable On-Line Execution algorithm (SOLE, for short) for continuous and on-line evaluation of concurrent continuous spatio- temporal queries over data str...
Vehicle tracking data is an essential “raw” material for a broad range of applications such as traffic management and control, routing, and navigation. An important issue with...
