Delphi is a high-level, compiled programming language and integrated development environment (IDE) used for rapid application development (RAD) of desktop, mobile, web, and database applications. Based on the Object Pascal language, Delphi provides an extensive set of visual components and libraries, allowing developers to build rich user interfaces and connect to various databases with minimal coding. Known for its fast compilation and cross-platform capabilities, Delphi enables the creation of efficient, native applications for Windows, macOS, iOS, and Android. It is widely used in industries requiring robust, high-performance software with a strong focus on productivity.
