The record

Purpose: MonetDB is a high-performance relational database system for analytics.
SQL and transactions: It provides a SQL-compliant interface with keys, joins, views, triggers, stored procedures, and full ACID properties for concurrent transactions.
Columnar analytics: Its query execution uses a columnar storage model and parallel execution plans optimized for heavy analytical workloads.
User-defined functions: MonetDB supports aggregate, filter, window, and table-returning SQL user-defined functions.
Architecture: Tables are stored using vertical fragmentation, with each column represented as a Binary Association Table and persistent BATs implemented as memory-mapped files.
Primary workload: The system is designed primarily for data-warehouse environments and bulk processing, including business intelligence and scientific analysis.
Transaction limit: Although MonetDB provides a full SQL interface, it has not been tuned for high-volume transaction processing.
Supported operating systems: Prebuilt packages are available for 64-bit Linux distributions, 64-bit macOS, and 32-bit or 64-bit Windows.
Programming interfaces: Native interface libraries are available for Python, Java JDBC, Node.js, PHP, Perl, Ruby, R, Go, and C# .NET, with a separate ODBC installer.
Integrations: The ecosystem lists integrations including a PostgreSQL foreign data wrapper, SQLAlchemy dialect, Django backend, Tableau connector, and GeoTools datastore.
Security: Client-server communication is unencrypted by default; TLS can be used through a termination proxy such as stunnel.
Support: The foundation provides documentation, Q&A, troubleshooting, and best-practice advice, while commercial support is available from MonetDB Solutions.
Users: The foundation says MonetDB is used by researchers, teachers, students, commercial companies, and government organisations in mission-critical applications.
Founded: 2004
