PROBE spatial data modeling and query processing in an image database application

The PROBE research project has produced results in the areas of data modeling, spatial/temporal query processing, recursive query processing, and database system architecture for nontraditional application areas, many of which involve spatial data and data with complex structure. An overview of PROBE is provided, focusing on the facilities for dealing with spatial and temporal data. It is shown how the PROBE database system and simple application-specific object classes combine to efficiently support PROBE´s spatial data model. It is also shown how an image-database application can be supported using PROBE´s data model and spatial query processor. The current status of the PROBE project and future plans are discussed
