System Architecture

CUBRID is an object-relational database management system (DBMS) consisting of the database server, the broker, and the CUBRID Manager.

  • As the core component of the CUBRID database management system, the database server stores and manages data in multi-threaded client/server architecture. The database server processes the queries requested by users and manages objects in the database. The CUBRID database server provides seamless transactions using locking and logging methods even when multiple users use the database at once. It also supports database backup and restore for the operation.
  • The broker is a CUBRID-specific middleware that relays the communication between the database server and external applications. It provides functions including connection pooling, monitoring, and log tracing and analysis.
  • The CUBRID Manager is a GUI tool that allows users to remotely manage the database and the broker. It also provides the Query Editor, a convenient tool that allows users to execute SQL queries on the database server. For more information about CUBRID Manager, see

Note CUBRID Query Browser is a light version of CUBRID Manager and provides only the features that application developers absolute need: the database management and query editor features. For more details on CUBRID Query Browse, see
