`!Linter SQL RDBMS`! is the main product of RELEX Group. Linter is a Russian DBMS compliant with the `F33f`_`[SQL:2003`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=SQL:2003]`_`f standard`:cite-ref-1[`F5bf`_`[1`#cite-note-1]`_`f] and supporting the majority of operating systems, among them `F33f`_`[Windows`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Microsoft_Windows]`_`f, various versions of `F33f`_`[Unix`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Unix]`_`f, `F33f`_`[QNX`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=QNX]`_`f, and others. The system enables transparent interaction between the client `F33f`_`[applications`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Application_software]`_`f and the database server functioning in different `F33f`_`[hardware`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Computer_hardware]`_`f and `F33f`_`[software`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Computer_software]`_`f environments. DBMS Linter includes program `F33f`_`[interfaces`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Interface_(computer_science)]`_`f for the majority of popular development tools. The system provides a high `F33f`_`[data security`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Data_security]`_`f level allowing the user to work with secret information. Linter is the only `F33f`_`[DBMS`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=DBMS]`_`f certified by FSTEC of Russia as compliant with Class 2 data security requirements and Level 2 of undeclared feature absence control. For many years Linter has been used by Russian `F33f`_`[Ministry of Defense`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Ministry_of_Defence_(Russia)]`_`f, `F33f`_`[Ministry of Foreign Affairs`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Ministry_of_Foreign_Affairs_(Russia)]`_`f and other government bodies.

>>History
The history of Linter dates back to 1980. The system has domestic predecessors whose developers later took direct part in the creation of Linter. By 1983, according to a state order, the `F33f`_`[Voronezh`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Voronezh]`_`f construction design office "Systemprogramm" had successfully completed the relational DBMS "BARS" under the `F33f`_`[real-time operating system`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Real-time_operating_system]`_`f "RAFOS" (`F33f`_`[RT-11`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=RT-11]`_`f prototype) for computers of the SM set. Since 1985, the system developers accepted the mobility, compatibility and openness concept. As a result, DBMS "INTEREAL" was implemented.
The system covered a wide spectrum of hardware and software platforms, from "Electronika-85" and `F33f`_`[Intel 8086`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Intel_8086]`_`f control modules to SM1702 and "Electronika-82" computer complexes and their `F33f`_`[VAX`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=VAX]`_`f prototypes. In 1990, the DBMS development team founded the research-and-production company "RELEX" ("Relational Expert Systems"). At this time DBMS Linter was launched.
In the late 1990s, Linter-VS 6.0 was developed as part of a project performed by RELEX for the Russian Ministry of Defense. The prototype of the system was Linter 5.7 (1999) developed by RELEX. Linter-VS 6.0 is available only for OS MSVS (mobile system of the armed forces). There also exists Linter-VS 6.0.1 developed in VNIINS based on `F33f`_`[PostgreSQL`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=PostgreSQL]`_`f 7.2 This system is also available for OS MSVS.
RelX Embedded, a compact American/Japanese-developed version of Linter is implemented in `F33f`_`[Sony`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Sony]`_`f products, including a Linter phone (Sony Ericsson SO903i),`:cite-ref-2[`F5bf`_`[2`#cite-note-2]`_`f] as well as a `F33f`_`[Kenwood`:/page/wikibook/entry.mu`zim=wikipedia_en_all_nopic_2025-08.zim|entry_path=Kenwood_Corporation]`_`f Navigation System ("HDD[Smá:t]Navi Emotional Sound" HDV-990 and HDV-790).`:cite-ref-3[`F5bf`_`[3`#cite-note-3]`_`f]
