Borland Delphi is a software development suite that includes a programming language, Integrated Development Environment (IDE), and various tools and libraries. It is developed by Embarcadero Technologies, a subsidiary of Idera, Inc. Delphi is a high-level, object-oriented programming language that is designed to be easy to use and highly expressive. It is based on the Pascal programming language, with additional features and syntax borrowed from other languages such as C++, C#, and Java.

Delphi is used to develop a wide range of business software solutions, including desktop applications, mobile apps, web applications, and database-driven systems. It is particularly well-suited for developing Windows applications, but it can also be used to develop applications for macOS, Linux, iOS, and Android.

The Delphi IDE is a powerful tool for developing software applications. It includes a code editor, debugger, compiler, and various other tools and utilities that make it easier to write, test, and debug code. Delphi also includes a large library of pre-built components and functions, which can be used to build common features such as user interfaces, database connectivity, and networking.

In addition to its core product offering, Embarcadero also provides a range of additional tools and services for Delphi developers, including database management tools, application lifecycle management tools, and training and support resources.

Overall, Borland Delphi is a powerful and versatile software development suite that can be used to develop a wide range of business software solutions. It is particularly well-suited for developing Windows applications, but it can also be used to develop applications for other platforms.
