Concentric Data Systems, Inc., established in December 1979 by John J. Henderson and Jonathan Sachs, who were previously system programmers at Data General Corporation, began by offering software consulting services specifically for Data General machines. In 1981, the firm created CompuCalc, a spreadsheet application inspired by VisiCalc designed for use on Data General platforms.

In 1982, Sachs departed to co-found Lotus Development Corporation alongside Mitch Kapor.

Following this, Concentric redirected its efforts towards developing products for the IBM PC. The company introduced a file management tool named C.I.P, then launched Lotus 1-2-3 Report Writer, along with a collection of report writing software branded as R&R. These R&R solutions were compatible with dBase, FoxBase, FoxPro, and multiple SQL database systems.

In 1995, Wall Data Corporation based in Kirkland, WA acquired Concentric.

By 1999, the copyrights and intellectual property rights for the complete R&R and Arpeggio product suites were purchased from Wall Data by Liveware Publishing, Inc.. The R&R software has been continually enhanced since then and remains commercially available.
