Many dBASE developers would eventually start working in the closely related Fox Software / Microsoft FoxPro system.Īshton-Tate also released a Macintosh database under the dBase name, called "dBase Mac". It was eventually sold to Borland in 1991, who then continued to sell dBase III Plus as well as IV. This version would be seen as its downfall, as it was slow, buggy, slow, incompatible, slow, and unable to compete against newer SQL offerings.
In 1988, after years of promises to rewrite, Ashton-Tate released dBASE IV. By the start of 1984 dBASE II had retained about 70% of the computer database market with over 150,000 copies sold. In 1982, enjoying large success on CP/M, dBASE II was ported to DOS and the IBM PC. At the time of conception Ashton-Tate was a garage based company but quickly grew. It was regarded as one of the killer applications for CP/M, and achieved good success. Ashton-Tate dBase was an early popular database management system for CP/M and MS-DOS.
