Borland Reflex

Borland Reflex is a flat-file database management system for DOS.

It was the first commercial PC database to use the mouse and graphics mode, and drag-and-drop capability in the report formatting module.

[1][2][3] The engineering team of Analytica, managed by Brad Silverberg and including Reflex co-founder Adam Bosworth became the core of Borland's engineering team in the U.S. Brad Silverberg was vice-president of engineering until he left in early 1990 to head up the Personal Systems division at Microsoft.

Another Reflex developer, Ken Day, later moved to Macromedia where he worked on Shockwave, among other projects.
