Affiliation with Omnibase/SmartStar

An announcement was made in 1984, that Britton-Lee's ''Intelligent Database Machine'' (IDM) was being sold together with Signal Technology Inc.'s Omnibase and SmartStar relational database software. This hardware/software combination of Omnibase/Smartstar/Britton Lee Data Base Machine(s), was used by

SmartStar is Signal Technology Inc (STI)'s application development environment for the VAX, and it supports several databases using native connections: :: RMS, Rdb/VMS, Oracle, Sybase, Ingres, Teradata/ShareBase. Although before SQL became standard STI's focus was on IQL (Interactive Query Language), now the query language it supports is SQL. Components include * ''SmartBuilder'' * ''SmartDesign'' * ''SmartStation'' * ''SmartGL'' * ''SmartCall'' and ''RSQL'' (for use from 3GL languages) * ''SmartQuery'' * ''SmartMove'' (mass load/unload) * ''SmartReport'' * ''SmartPainter'' * ''ISQL'' (Interactive SQL)


Signal Technology Inc

As the above combination moved along, STI and Britton-Lee saw a validation in the form of a review, which confirmed: "there exists no database management system that matches the performance of the IDM with OMNIBASE."{{cite journal , journal=Data Processing , volume = 28, issue = 9, pages = 482–484, quote=Smartstar, and Omnibase/. Britton-Lee, among others. After making a shortlist, they decided that Focus would make them generate too much non-procedural. , title=Application of a fourth-generation environment, doi = 10.1016/0011-684X(86)90317-5, year = 1986, last1 = Exton-Smith, first1 = Howard
