The phrase rapid application development was a concept made famous by Borland Delphi (now Embarcadero Delphi) nearly two decades ago. Delphi came with an impressive library of ready to use components, re-usable classes and functions that set a new standard in productivity. Delphi is still knocking out killer apps even today and is experiencing somewhat of a revival in the IT community. The visual component library and the fact that you can easily re-use and extend these controls means that you can do more in less time. You focus on writing your app rather than wasting time re-inventing the wheel over and over again.
