Accent R (the "R" is for Relational: Relational database, Relational model), is a fourth-generation programming language that was first installed in 1980.[1] Initially available for Digital Equipment Corporation's DECsystem-10[2] and DECSYSTEM-20, a VAX version was released and installed January 1982.[3]
It was developed by National Information Systems, Inc (NIS), and contains a compiled[4] structured programming language that can replace 3GL coding. Accent R goes beyond use of RMS: Oracle[3] and Sybase[5] are among the database systems supported.
Accent R is also supported on Linux.[6]
About National Information Systems, Inc (NIS)
[edit]National Information Systems, initially a Silicon Valley company, was founded in 1972 as a software company focused on providing tools for software developers. Their DPL (Data Processing Language),[7] written for the DECsystem-10 and DECSYSTEM-20, competed with Software House's System 1022. Both were used in the financial services industry, where some companies used both.[citation needed]
By 1988 NIS worked out and announced a cooperative marketing agreement with Sybase.[8]
The company's headquarters are now in Reno, Nevada.
