Delphi is a well-known rapid application development tool (Rapid Application Development, RAD) under the Windows platform. Its predecessor was the “Borland Turbo Pascal” that was popular in the DOS era. The earliest version was developed by the American Borland company in 1995. The main creator is Anders Hejlsberg.
