Since 1998, DataPixel has developed a number of software titles with Helix RADE for operating systems prior to Mac OS X. Some received interface modifications to make them appear more like Mac OS X while running in Classic. (There is no affiliation with DataPixel.com of Spain.)
The distributor of Helix, QSA ToolWorks, offers Mac OS X versions of Client, Server and Runtime Engine software. On June 10, 2013 the OS X native version of the Rapid Application Development Environment, Helix RADE was made available.
Helix RADE is a relational database tool for developing applications in object code. Recent effort has been focused on AppleScript structure manipulation. Consult The Latest Word on the QSA ToolWorks website for current news regarding Helix development.
