Delphi is a general purpose development environment for all versions of Windows. Delphi Programming is the most powerful tool available for software developers working on the Windows platform. It can produce any kind of Windows application, including Service and Console applications, IIS extensions, etc, but in the specific case of GUI applications and database access, it is the best tool available, bar none.
Delphi can create programs that run on any version of Windows, access every major kind of Database, including ORACLE, SQL Server, DB2, Interbase, Firebird, and supports n-tier and Client/Server architectures. Delphi Language has always supported native (Win32) development but also provides support for .Net development and, soon according to the current roadmap, will include support for native 64 bit and the newest .Net releases.
Delphi is one of the most respected and widely used Rapid Application Development (RAD) environments today. Over 1.7 million developers worldwide choose Delphi over other tools because Delphi radically speeds desktop, workstation, touch, kiosk, and Web application development without sacrificing an ounce of programming power or control. Applications built with Delphi are lightning fast, compact, provide rich UIs, and can connect with virtually any database or data source out-of-the-box.
With Delphi, you can:
RADically reduce development time and build Windows applications up to 5x faster than with other development solutions
Speed your way from prototype to production with visual drag-and-drop tools and a powerful component library
Free your customers from keyboards with dazzling touch based UIs
Delphi, considered as a powerful Rapid Application Development (RAD) tool developed by Borland, supports full OOP concepts enhancing reusability and ease of use and comes with an integrated IDE. The Delphi products all ship with a large framework called VCL (Visual Component Library) including most of its source code. The IDE includes a GUI for localization and translation of created programs which may be deployed to a translator at no additional cost. The VCL framework maintains a high level of source compatibility between versions which means one can upgrade existing source code easily in most cases to a newer Delphi version
