OlegDB is a free, open-source, NoSQL (Key-Value) DBMS. It was primarily written in C, with a Go frontend layer, and is compatible with any POSIX compliant operating system. The user can communicate with OlegDB using a simple REST API. They are also encouraged to adapt the system to their needs through several well-documented toggleable parameters.
OlegDB was created in January 2014, by a small team of international developers led by Quinlan Pfiffer. OlegDB first started as a humorous and personal project following the popularity surge of non-relational models at the beginning of the 21st century. However, the authors eventually released an open-source, licensed implementation at the end of March 2014. Several updated versions have been made public since then, the latest one dating back to January 2015, when the frontend code was migrated from Erlang to Go.
