Let me give you some perspetive....
Data Management+ Laboratory
Spatial Data Types
Spatial Databases
deal with large collections of geometric objects (e.g., rectangle, point, polygon) in space.
Data Management+ Lab
Spatiotemporal databases
manage both space and time information,
e.g., tracking moving objects (mobile users).
Research Topics
Application Domains
Users, Application Domains
Location-based services
Bioinformatics modeling on e.g. a rat brain

a very large, integrated collection of data.
Research Topics
Moving Object Processing
Continuous Query Processing
e.g., 舉Look for a nearest gas station on my way to a mall.

Research Topics
Mutliple-dimentional Databases
Demo System: SkyEngine: Efficient Skyline Search Engine for Continuous Skyline Computations
Demo System: PLUS: A Message-Efficient Prototype
for Location-Based Applications

Future Trends
Cloud Computing: Software as Service and Data as Service in supporting light-weight client apps will be on-demand dramatically.
Lines: river
Points: restaurants
Polygons: lake
