Distinguishing features

Borland Delphi and Kylix use the Pascal-based Delphi programming language, and compile Delphi source code into native x86 code or managed .NET code. A compiler is a Computer program (or set of programs that translates text written in a computer language (the source language) into another In Computer science, source code (commonly just source or code) is any sequence of statements or declarations written in some Human-readable See also X86 assembly language The generic term x86 refers to the most commercially successful Instruction set architecture in the history of Personal They include the VCL/CLX (Visual Component Library), support for COM independent interfaces with reference counted class implementations, and support for a large number of third-party components. VCL (Visual Component Library is a visual component -based framework for developing Microsoft Windows applications developed by Borland for use in its Component Library for Cross Platform (CLX (pronounced clicks is a cross-platform visual component-based framework for developing Microsoft Windows and Linux applications Component Object Model ( COM) is an interface standard for Software componentry introduced by Microsoft in 1993 In Computer science, reference counting is a technique of storing the number of references pointers or handles to a resource such as an object or block of memory Interface implementations can be delegated to fields or properties of classes. Interface generally refers to an abstraction that an entity provides of itself to the outside Message handlers are implemented by tagging a method of a class with the integer constant of the message to handle. A strong emphasis is placed on database connectivity.

History

Turbo Pascal, later Borland Pascal, was a low-cost, high-quality compiler, revolutionary when first introduced. Turbo Pascal is a complete software development system that includes a Compiler and an Integrated Development Environment (IDE for the Pascal programming language It went through a number of revisions over the years, and was used mainly to produce programs to run on text displays. When the use of graphical user interfaces became viable with Microsoft Windows 3, Delphi, using augmented Borland Pascal as its underlying language, was introduced. Microsoft Windows is a series of Software Operating systems and Graphical user interfaces produced by Microsoft. Delphi was one of the first of what came to be known as Rapid Application Development (RAD) tools when released in 1995 for the 16-bit Windows 3.1. Rapid application development ( RAD) is a Software development process, which involves iterative development and the construction of Prototypes Year 1995 ( MCMXCV) was a Common year starting on Sunday. Events of 1995 Delphi 2, released a year later, supported 32-bit Windows environments, and a variant using C++ as the underlying language, C++ Builder, followed a few years later.

In 2001 a Linux version named Kylix was released. Year 2001 ( MMI) was a Common year starting on Monday according to the Gregorian calendar. It was criticised as being of low quality and did not sell well, and was abandoned after version 3.

Support for Linux and Windows cross-platform development (through Kylix and the CLX component library) was added in 2002 with the release of Delphi 6. See also 2002 (disambiguation Year 2002 ( MMII) was a Common year starting on Tuesday of the Gregorian calendar.

Common Intermediate Language (CIL pronounced either "sil" or "kil" (formerly called Microsoft Intermediate Language or MSIL is the lowest-level Human-readable It was also significant in that it changed its IDE for the first time, from the multiple-floating-window-on-desktop style IDE to a look and feel similar to Microsoft's Visual Studio. Look and feel is a term used in descriptions of products and fields such as Marketing, Branding and Trademarking to signify the experience a person has using NET. The new IDEs still have the "Classic Undocked" windows layout available as an option.

The next version, Delphi 2005 (Delphi 9), included the Win32 and . NET development in a single IDE, reiterating Borland's commitment to Win32 developers. Delphi 2005 includes design-time manipulation of live data from a database. It also includes an improved IDE and added a for . . . in statement (like C#'s foreach) to the language. For each (or foreach) is a Computer language idiom for traversing items in a collection. However, it was criticized by some for its bugs; both Delphi 8 and Delphi 2005 had stability problems when shipped, which were only partially resolved in service packs.

In late 2005 Delphi 2006 was released and combined development of C# and Delphi. Year 2005 ( MMV) was a Common year starting on Saturday (link displays full calendar of the Gregorian calendar. NET, Delphi Win32 and C++ into a single IDE. It was much more stable than Delphi 8 or Delphi 2005 when shipped, and improved even more with the release of service packs and several hotfixes.

On February 8, 2006 Borland announced that it was looking for a buyer for its IDE and database line of products, which include Delphi, to concentrate on its ALM line.

Each version is available in two editions: Explorer—a free downloadable version—and Professional—a lower-priced (US$899 for new user, US$399 for update) version which opens access to thousands of third-party components. Unlike earlier Personal editions of Delphi, new Explorer editions can be used for commercial development.

On November 14, 2006 Borland announced that rather than selling the development tools group it would spin it off into an independent subsidiary company named CodeGear.

New features included support for MS Build and enhancements to the Visual Component Library for Windows Vista. CodeGear also introduced DBX4 as the next version of dbExpress. For the first time Delphi could be downloaded from the Internet and activated with a license key. International customers were served by releasing version 7 simultaneously in English, French, German and Japanese. RAD Studio 2007, which includes . NET development, was released on September 5, 2007.

Name

Delphi was originally a confidential research project at Borland which evolved into a product that was to be called AppBuilder. Borland Software Corporation is a software company headquartered in Austin Texas.

Developer Danny Thorpe chose the Delphi codename in reference to the Oracle at Delphi. Danny Thorpe is a software developer currently working on developer tools at Microsoft. PYTHIA is a computer simulation program for particle collisions at very high energies (see Event (particle physics) in Particle accelerators One of the original goals of Delphi was to provide database connectivity to programmers as a key feature and a popular database package at the time was Oracle database; hence, "If you want to talk to [the] Oracle, go to Delphi". Oracle Database (commonly referred to as Oracle RDBMS or simply Oracle) is a Relational database management system (RDBMS produced and marketed by As development continued, the name grew on them and there was growing support within Borland for the name Delphi.

Shortly before the first release of Borland's AppBuilder, Novell AppBuilder was released, leaving Borland in need of a new name. After much struggle, the name Delphi prevailed. [3]

Products developed with Delphi

Among the many products developed with Delphi are:

Clones and alternatives

There are several compilers of the Object Pascal originally developed by Borland, and also products that supply an entire development framework as Delphi does. Object Pascal refers to a branch of object oriented derivatives of Pascal, mostly known as the primary Programming language of CodeGear Delphi

Some of these can do things that Delphi cannot, such as supporting different operating systems, and allowing examination of the compiler source code. They are sometimes used to get the server parts of Delphi applications running on operating systems other than Microsoft Windows. Most had Linux support years before Kylix.
