PowerBuilder is a programming language created by Powersoft which was later purchased by Sybase. It is an event driven language used for Rapid application development (RAD). The word 'Powerbuilder' also applies to the integrated development environment used with the language.

PowerBuilder also includes a scripting language, Powerscript, which is used to specify the application behavior when events occur. Events usually correspond to user actions, such as clicking on an element of the user interface, or closing a window. Powerbuilder is used primarily for building business applications, but could theoretically be used to create any kind of application. Powerbuilder and the applications built with it are used exclusively on Microsoft Windows computers.

The PowerBuilder training series provides an introduction to PowerBuilder 6 and its development environment. It describes PowerBuilder's main components and explains how to create and manage libraries, use the Application Painter, and create menus and windows. The concepts of design are presented, and building objects is covered in detail. Also examined in detail is building windows, event programming, creating and using Data Windows, and using SQL commands to interact with databases in PowerBuilder applications. Additional topics covered include providing reports and implementingfinal touches in a PowerBuilder program, and how to debug an application and create an executable program.
