Data for Database Research
Sometimes, it can be hard to find just the right time series for testing a new algorithm.
My own stuff
I have my own data repository. Quite modest!

- Earthquake Catalogs & Data (Seismic waveforms)
Astronomy
- Sloan Digital Sky Survey (access is through online SQL queries)
- The Sunspot Cycle (sun spots time series)
Motion Capture
- CMU Graphics Lab Motion Capture Database (includes time series)
Biomedical
