MonetDB/SQL is a full-fledged relational ("SQL") DBMS optimized for (but not restricted to) analytical workloads as in, i.e., OLAP, data mining and BI. To achieve is query processing speed, MonetDB uses cutting-edge column store technology and is highly optimized for hardware-aware in-memory processing exploiting large amounts of main-memory However, data is persistently stored on disk as in any other (disk-based) relational DBMS. Data is written to disk whenever transaction policies require that. MonetDB/SQL provides ACID-compliant transaction.
