CUBRID
CUBRID is a free, self-hosted object-relational database management system for Internet data services.
What CUBRID is
CUBRID is a free, self-hosted object-relational database management system for Internet data services. Its architecture includes a database server, broker, and CUBRID Manager. Transactions support commit, rollback, and savepoints, with locking and logging for consistency. Backup options are online, offline, and incremental, while recovery can be partial or full. CUBRID HA synchronizes data between servers and can fail over when a master node fails, although HA supports Linux only. Security documentation covers TLS-encrypted client connections, access control, authorization, and transparent data encryption. Interfaces include CCI, JDBC, PHP, ODBC, OLE DB, ADO.NET, Ruby, Python, and Node.js. Downloads include CUBRID Manager and the Migration Toolkit. Installation documentation lists Windows and 64-bit Linux, requiring at least 1 GB memory and 2 GB disk space. The engine is listed as free under Apache License 2.0; APIs use BSD licensing.
