Along with Microsoft and Lotus, Ashton-Tate was one of the big three software companies of the 1980s. It began life as a garage outfit called Software Plus, Inc (SPI) in 1980 and went on to create the first major database managements system for microcomputers, dBase.
An IBM-compatible version of dBase II came out in 1983 to great success, and in the same year the company became Ashton-Tate and went public. It released the C-written dBase III (opening screen for dBase III+ pictured above) in 1984, but later that year co-founder George Tate died of a heart attack. Company president David Cole briefly took over, but marketing man Ed Esber quickly succeeded him (Cole went to work for Ziff-Davis, which founded this publication).
Esber led the company very successfully for seven years, but he became known for being litigious, particularly when it came to companies that released dBase clones. Large corporations kept on using dBase, but smaller businesses deserted the platform. The 1988 version of dBase IV was slow and unstable, but rather than fix the bugs, the company concentrated instead on its next planned product line. The update for dBase IV only came out in 1990, by which time sales were down drastically.
Having turned down several merger opportunities — including with Microsoft and Symantec — Ashton-Tate finally merged with Borland in 1991. However, Microsoft introduced Access in 1992, trouncing dBase in the Windows marketplace.
