SQLite has a backend which is well suited as a key-value store. Here is a NoSql database based on the SQLite backend: https://github.com/rochus-keller/Udb https://github.com/rochus-keller/Udb. I use it in many of my apps, e.g. https://github.com/rochus-keller/CrossLine https://github.com/rochus-keller/CrossLine. It's lean and fast, and supports objects, indices, hierarchical "globals" like ANSI-M and transactions.
