Wikipedia
RAMIS, the first 4GL, was the direct ancestor of FOCUS, having been principally developed by Gerald D. Cohen and Peter Mittelman while working at Mathematica Products Group in 1970.
The product was sold by Mathematica to a number of in-house clients ( including Nabisco and AT & T ), and was also offered by the National CSS timesharing company for use on their VP / CSS operating system ( a derivation of IBM's CP / CMS which is now called VM / CMS ).
In 1970, Cohen decided to leave Mathematica and form Information Builders, after which he recreated the product he had built at Mathematica in the form of FOCUS which was released in 1975.
The syntax of FOCUS in its simplest elements is almost a direct clone of the syntax of RAMIS bearing a resemblance similar to the differences between various early dialects of SQL ).
All three products flourished during the 1970s and early 1980s, but Mathematica's time ran out in the mid-80s, and NCSS also failed, a victim of the personal computing revolution which obviated commercial timesharing ( although it has since been revived in the form of ASPs and shared web servers ).
