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. High Availability option maintains two copies of the data synchronized at all times. In case of system failure, applications can recover access to solidDB in less than a second without loss of data. solidDB is easy to deploy and administer, with the ability to be embedded directly into applications and run virtually unattended for lower total cost-of-ownership.
It is historically 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.
