MQP Projects in CAPE
 Work on core engine, such as query processor,
scheduler, query approximator, data shedder,
distributer, resource allocator, etc.
 Develop full example application, e.g.: TRAFFIC,
 Load real data streams : traffic simulation
 Develop useful queries, like “average density in city
region X over last 5 minute window”
 Provide GUI to specify query, eg. By drawing a
rectangle over city map.
 Supply visual results to traffic monitor, e.g., in charts
of time trends.
