solidDB is an in-memory relational database management system developed and sold by UNICOM Global. solidDB delivers extreme speed as a persistent, relational in-memory database that meets performance and reliability demands of real-time applications. Unicom Global, known as UNICOM Government, Inc. is an American information technology (IT) hardware and solutions company,^[1][2] founded in 1983 to provide microcomputer software to the federal government of the United States.^[2] By 1986, it worked with local, state and federal government agencies.^[2] In 1996, it registered its URL and engaged in e-commerce.^[2]

Technology[]

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]} 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.^{[citation needed]}

Customers[]

It is historically used as an embedded database in telecommunications equipment, network software, and similar systems.^[3] Companies using solidDB include Alcatel-Lucent, Ericsson, Cisco Systems, EMC Corporation, Hewlett-Packard, Nokia, Siemens AG and Nokia Networks.

History[]

Solid was acquired by IBM in late 2007.^[4] It was a privately held company founded in Helsinki, Finland in 1992. Solid was sold to UNICOM Global in 2014.^[5]
