| SpADE Overview: |
-What
is SpADE?
|
| SpADE is the abbreviation of
SPatio-temporal Automatic
Database Engine for location-aware servieces. |
| |
| -Motivation |
The objectives of the project are to review
the requirement for moving object applications,
and propose various techniques that could be
used to provide both effective and efficient
database support for LBS. The expected research
deliverables and achievements include:
- A novel modeling method for spatial-temporal data. Different approaches will be explored based on the nature and application scenario of the data.
- Efficient spatial-temporal indexing structures for supporting spatial-temporal data, in particular, moving objects, with and without the support for historical data.
- An efficient concurrency control to facilitate the manipulation of spatial-temporal data.
- Buffer replacement strategies for reducing page accesses.
- Autonomic data distribution strategies based on query locations and patterns.
- Efficient operations for providing Nearest Neighbor (NN) and K Nearest Neighbor (KNN) searches, reverse KNN and KNN join will be designed based on the proposed indexes.
- Human-computer interactions including user interfaces design, in particular, the user interfaces using the new positioning and telecommunication devices.
- Visualization methods and tools for query results.

-Achievements
|
A prototype has been built with a novel indexing
scheme and the technical achievements are as
follows:
- Server console framework.
- Server backend database definition and access
module.
- Server side communication module.
- Client side map module.
- Client side light weight R-tree.
- Client side GPS module.
- Client side communication module.
- Client side human-machine interaction.
- Visualization tools and methods for query results.
- Server side Bx-tree index on MySQL.
- Server side query processing strategies with Bx-tree.
- Query results caching on client side small devices.
