solidDB is an in-memory relational database management system developed and sold by UNICOM Global. solidDB is designed for extreme speed as a persistent, relational in-memory database to meet performance and reliability demands of real-time applications.
solidDB includes an in-memory database as well as a traditional disk based database, which both employ the same SQL interface, and a high availability option. Both in-memory and disk based engines coexist inside the same server process, and a single SQL statement can access data from both engines.[citation needed] The High Availability option maintains two copies of the data synchronized at all times. solidDB can be embedded directly into applications and run virtually unattended for lower total cost-of-ownership.[citation needed]
SolidDB has historically been used as an embedded database in telecommunications equipment, network software, and similar systems. Companies using solidDB include Alcatel-Lucent, Ericsson, Cisco Systems, EMC Corporation, Hewlett-Packard, Nokia, Siemens AG and Nokia Networks.[citation needed]
Solid was a privately held company founded in Helsinki, Finland in 1992. Solid was acquired by IBM in late 2007. SolidDB was sold to UNICOM Global in 2014.
