dBASE IV v1.1

Ashton-Tate dBase was an early popular database management system for CP/M and MS-DOS. It was regarded as one of the killer applications for CP/M that achieved good success, as license prices were around $700 per installation for dBASE II. At the time of conception Ashton-Tate was a garage based company but quickly grew into one of the 'big three' software companies.

Enjoying large success on CP/M dBASE II was ported to DOS and the IBM PC in 1982. By the start of 1984 dBASE II had retained about 70% of the computer database market with over 150,000 copies sold.

After 2 years since announcement, Ashton-Tate released dBASE IV in 1988 which would be seen as it's downfall, as it was unable to compete against newer SQL offerings. It was eventually sold to Borland in 1991. Many dBASE developers would eventually start working in the closely related Fox Software / Microsoft FoxPro system.
