Delphi Programming Tutorials

The Delphi programming language is used mostly for the development of desktop and enterprise software. It is a further development of Pascal, and it adds an object-oriented programming extension. Delphi is a high-level programming language, and it can be used for programming Windows applications, including .NET applications. Its main functionality is provided by class libraries, although it is possible to use Windows API directly. The Delphi programming language is easy to learn and applications are easy to write. The latest version, Delphi 2009, supports Unicode for an easy internationalization of programs.

Several widely used programs are written in Delphi, such as restaurant pos systems (point-of-sale). This is because the programs are fast and stable, and the database functions are included in Delphi. Basic accounting and inventory features are also easy to implement.

Pascal was designed with the purpose of creating a programming language that is easy to learn and easy to teach. Since Delphi is based on Pascal, the language includes many of the clear and safe features; for example, variables can be declared only at specific positions. One of the biggest advantages of Delphi is the high type safety that shortens the debugging process, since many errors are already found at compile time. Several standards for writing Pascal and Delphi code have been established since the development of the first Pascal version in the 1970s. Everyone who writes in Delphi should stick to these standards since they can help to develop fast programs that are easy to debug. If you want to participate in the huge, worldwide Delphi community, a clear and standard-conform programming style is absolutely necessary.
