Thoughts on Time-series Databases

All we use are strip charts. It's all I saw at Boeing as well (through some proprietary charting software IIRC). What I'd like is some "rich" time series data format that stores a history of modifications (removing noise, filtering etc.), and an overall better interface for scrolling through the data (Windaq is pretty barebones).

Wow, that is pretty rough. That's so rough that I would consider figuring out some way to export your data from that software and then visualize it with python/matplotlib or similar.

I've been working on a Python module to read the files directly: https://github.com/choj/cldumpread/tree/master/WindaqReader/.... Scipy/numpy/matplotlib totally opens up what we can do with the data. The hard part is convincing a mechanical engineering manager who's extremely averse to new tools.

I've been there. Once I had to jump through huge hoops just to be allowed to install Python on a machine not connected to any networks.

I remember talking to someone that had an in-house flight test data warehouse with these kind of features, I think it might have been Cessna - give their FT dept a ring :)
