CUBRID vs Firebird

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

Firebird is a free, open-source relational database management system with ANSI SQL features. It runs on Linux, macOS, and Windows, and supports self-hosted deployment. Its multi-generation architecture generally allows readers to access data without blocking writers. SQL features include stored procedures, triggers, common table expressions, cross-database queries, and flexible transaction management. A Trace API and monitoring tables support real-time monitoring, SQL debugging, and auditing. Security controls include users and roles, GRANT and REVOKE permissions, and a database owner concept; Windows Trusted Authentication can integrate with Windows domain or Active Directory security. Deployment choices include embedded, SuperServer, SuperClassic, and Classic architectures. Backup options include online backups and dumps, as well as incremental backup with partly supported point-in-time recovery. Drivers include Java JDBC,.NET, Python, ODBC, PHP, Delphi, and C++ Builder. Free community support is available through mailing lists, alongside commercial and special support. Firebird lists versions 5.0.4, 4.0.7, and 3.0.14 as latest in their series; versions 2.5 and earlier are discontinued and no longer maintained. The enterprise subscription is €199 a month, billed from €199/month/1 servers.
