License BSD-3-Clause

Confirms the current value via BangDB's own documentation, which lists the community edition under BSD 3.

Released 2012

Corrects the current value of 2021-11, which is actually the BangDB 2.0 release date, not first availability. Founder Sachin Sinha states he developed BangDB in 2012; a July 2013 Wayback Machine capture of bangdb.com already promotes the database, corroborating an earlier launch.

Language C++

Confirms the current value via BangDB's own documentation, which states the server is written in C++; GitHub's own byte-count instead shows mostly Shell because only build scripts and prebuilt binaries are checked into the repo, not the C++ source.
