HiRDB is an evolving database for continuing business services.

HiRDB is a Japanese RDBMS (relational database management system) based on a "never-stop" design concept and exclusively developed by Hitachi. Since the mainframe era, Hitachi has been creating databases and other forms of IT infrastructure that support many social and enterprise systems. HiRDB, which evolved in open systems environment, is a database that inherits high-reliability technology and know-how cultivated in the mainframe fields. It has a proven track record of deployment, particularly in mission-critical fields.


Since the initial development of database technology, Hitachi has developed their own original mainframe databases using network data, hierarchical data, and relational data models. Since then, for more than 30 years, Hitachi has widely supported nationwide mission-critical information systems such as bank account online systems.

HiRDB is an open-platform relational database, inheriting mainframe database technologies with a proven track record. HiRDB is the embodiment of the various high-availability and high-reliability technologies that Hitachi has developed over the decades.
