Since 1999, 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.)
In the past couple of years, the distributor of Helix, QSA ToolWorks, has released Universal Mac OS X versions of Client, Server and Runtime Engine software. QSA ToolWorks is now hard at work modernizing the last component of the software suite: the Rapid Application Development Environment, Helix RADE.
Helix RADE is a relational database tool for developing applications in object code. Updating its code base is a long process that may not see the light of day even in 2010. But the Helix faithful continue to exercise patience. Consult The Latest Word on the QSA ToolWorks website for current news regarding Helix development.
