• 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.
