CUBRID (/ˈkjuːbrɪd/ "cube-rid") is an open source SQL-based relational database management system (RDBMS) with object extensions developed by Naver Corporation for web applications. The name CUBRID is a combination of the two words cube and bridge, cube standing for a sealed box that provides security for its contents while bridge standing for data bridge.
CUBRID has a separate license for its server engine and its interfaces. The server engine adopts the GPL v2.0 or later license, which allows distribution, modification, and acquisition of the source code. CUBRID APIs and GUI tools have the Berkeley Software Distribution license in which there is no obligation of opening derivative works. The reason of adopting two separate license systems is to provide complete freedom to Independent software vendors (ISV) to develop and distribute CUBRID-based applications.
The feature that distinguishes CUBRID database from other relational database systems is its 3-tier client-server architecture which consists of the database server, the connection broker and the application layer.
The database server is the component of the CUBRID database management system which is responsible for storage operations and statement execution. A CUBRID database server instance can mount and use a single database, making inter-database queries impossible. However, more than one instance can run on a machine.
Unlike other solutions, the database server does not compile queries itself, but executes queries precompiled in a custom access specification language.
The CUBRID connection broker's main roles are:
