Lesson plan

DBASE Mac

dBASE Mac was a database management system for the Apple Macintosh, released by Ashton-Tate in 1987. Although the GUI was lauded in the press, the application was so slow that it became something of a joke in the industry. Sales were dismal, and Ashton-Tate eventually decided to give up on dBASE Mac and instead port dBASE IV to the Mac, complete with a DOS-like interface. The product was then sold to a series of third-party developers, but they had little success and it disappeared from the market in the mid-1990s.
