MonetDB as a shared library with a C API.
MonetDBLite is an embedded SQL database that runs inside another program and does not require the installation of any external software. MonetDBLite is based on free and open-source MonetDB, a product of the Centrum Wiskunde & Informatica.
MonetDBLite is similar in functionality to SQLite, but optimized for analytical (OLAP) use cases.
