Which technologies you are using for building Data Explorer? This is interesting if it gets open sourced at some point in future. Do you use same stuff as with SO? C#, ASP.NET, MVC?

  • IMO this deserves to be a standalone faq now with the up-to-date answer. Commented Dec 22, 2013 at 17:46

Data Explorer

Like the rest of the Stack Exchange network, Data Explorer uses a WISC stack:

Data is populated into Data Explorer using an automated import script that converts and sanitizes data from the internal Stack Exchange databases, producing an output that is similar to the data dumps.

  • do you update the db as and when database dump is released ? Or do you have, er, "some other arrangement" ;p Commented Jun 2, 2010 at 0:51
  • no arrangement yet, but I will make sure that the latest data is up in very short order after the release

  • @Tim nice update! Where did you get all the information from? :) Commented Dec 22, 2013 at 17:42
  • @ShadowWizard Well, I know most of it, but otherwise I just copied from the network post under the assumption that it's the same.

  • @Brent aren't you consulting for Stack Exchange? If so, I think you should ask for a diamond here on Meta so you can edit anything at will. :) Commented Jan 18, 2014 at 21:10
  • @ShadowWizard well, I've got database access, so technically I can edit anything at will anyway. I try to be good and use the UI though. ;-)

While not strictly part of Data Explorer, it is possible to query Stack Overflow data as part of BigQuery's public datasets.

  • Also, it seems that the data available through BigQuery Public datasets program is updated from the internet archive dumps, on a quarterly fashion. As of december 2022, the latest data available via BQ is from September 2022
