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 Voronezh construction design office "Systemprogramm" had successfully completed the relational DBMS "BARS" under the real-time operating system "RAFOS" (RT-11 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 Intel 8086 control modules to SM1702 and "Electronika-82" computer complexes and their VAX 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 PostgreSQL 7.2 This system is also available for OS MSVS. RelX Embedded, a compact American/Japanese-developed version of Linter is implemented in Sony products, including a Linter phone (Sony Ericsson SO903i), as well as a Kenwood Navigation System ("HDD[Smá:t]Navi Emotional Sound" HDV-990 and HDV-790).
