query: Who is the CEO of Ashton-Tate?
passage: Ashton-Tate
In 1990 Esber proposed a merger with Borland. During the first discussions, the board backed out and dismissed Esber thinking him crazy to entertain a merger of equals (combining the companies at existing market valuations) with the smaller competitor Borland, and on February 11, 1991 replaced him as CEO with William P. "Bill" Lyons. Lyons had been hired to run the non-dBASE business and heretofore had been unsuccessful. Lyons would ship dBASE IV 1.1, a product Esber managed and was already in beta when let go.
passage: Ashton-Tate
Ashton-Tate purchased Decision Resources of Westport, Connecticut in 1986. Decision Resources had created the Chart Master, Sign Master, Map Master and Diagram Master programs. These were simple, effective business charting/drawing programs that counted on various spreadsheet programs being so poor at charting that people would gladly pay for another program to improve on them. By the time Ashton-Tate purchased the company it was clear that newer generations of spreadsheet programs would improve their charting abilities to the point where the Decision Resource products wouldn't be needed, but the company was also working on a new drawing package that was more interesting in the long run.
