1970’s
SQL- SQL was initially developed at IBM by Donald D. Chamberlin and Raymond F. Boyce in the early 1970s. This version, initially called SEQUEL (Structured English Query Language), was designed to manipulate and retrieve data stored in IBM's original quasi-relational database management system, System R, which a group at IBM San Jose Research Laboratory had developed during the 1970s. The acronym SEQUEL was later changed to SQL because "SEQUEL" was a trademark of the UK-based Hawker Siddeley aircraft company.
PASCAL- 1 Jan 1970
Pascal is an influential imperative and procedural programming language, designed in 1968/9 and published in 1970 by Niklaus Wirth as a small and efficient language intended to encourage good programming practices using structured programming and data structuring.

C- is a general-purpose computer programming language developed in 1972 by Dennis Ritchie at the Bell Telephone Laboratories for use with the Unix operating system. Although C was designed for implementing system software, it is also widely used for developing portable application software. C is one of the most popular programming languages of all time[5][6] and there are very few computer architectures for which a C compiler does not exist. C has greatly influence
FORTH- Forth evolved from Charles H. Moore's personal programming system, which had been in continuous development since 1958. Forth was first exposed to other programmers in the early 1970s, starting with Elizabeth Rather at the US National Radio Astronomy Observatory. After their work at NRAO, Charles Moore and Elizabeth Rather formed FORTH, Inc. in 1973, refining and porting Forth systems to dozens of other platforms in the next decade
Because Charles Moore had frequently moved from job to job over his career, an early pressure on the developing language was ease of porting to different computer
