The development of personal desktop computers led to the introduction of multi-tasking, multi-user operating systems such as Microsoft Windows. However, as a result, the process of creating software has become much more complicated. Visual integrated development environments (IDE) and rapid application development (RAD) systems were created by market leaders to facilitate the interaction with operating systems, reduce coding time, and improve the quality of the code.

Visual Programming is a process of building software applications in which a user can simultaneously design, edit, debug and test the app using Visual IDE. In other words, Visual Programming is a combination of two interconnected processes: designing an application window visually; and writing the code.

Delphi, a powerful Pascal compiler with a number of significant improvements for creating Windows applications, was first released in 1996.

It is a high-level software development system with an integrated tool set for developing complete applications; it is a tool for rapid application development. Visual design and event-based programming concepts are the pillars of Delphi ideology. Using those concepts significantly improves application design processes and greatly reduces development time.

Visual design allows users to lay out the application and see the results of the process prior to even starting the actual program. There are other benefits too: to assign a property value to a control or element of the app, it is not necessary to write multiple lines of code. All it takes is to change that value in a Properties window. This change will automatically generate or update the code.
