Toward an Active Database Platform for Guiding Urban Pedestrians
2012 (English)Report (Other academic)
We present an Android-based platform for incrementally presenting spoken route directionsto guide pedestrians to destinations. Our approach makes heavy use of stored proceduresand triggers in an underlyingPostGISspatial database. In fact most of the ’intelligence’of our prototype resides in database stored procedures and tables. As such it representsan example of a challenging real world case study for the use of persistent stored modules(PSM) in a complex mobility application. It also provides a platform to study performancetradeoffs for complex event processing over spatial data streams
