Visual programming language was primarily used in the 80s and 90s to create gaming kits, multimedia tools, and databases. Work on their Rational Unified Process and related efforts eventually led to the creation of Unified Modelling Language and that had the potential to document every last part of a system without ever writing a line of code. UML provided a standardized and comprehensive language for describing object-oriented systems. Visual programming has lacked the success of other programming languages for multiple reasons, however, it is not dead. For most developers, VPL is not a sustainable alternative to model software programs because real-life things are too complex to be coded only visually. For visual learning enthusiasts, the software tends to be limited by the imagination of the creator in a way that doesn’t hamper general-purpose textual programming languages.
Tools like Visual Basic, Delphi, and their descendants have shown us that building software visually can be enormously efficient. Today, we have a world where software development is made up of increasingly complex parts and where developers are ordinary people with extraordinary specializations. That complexity and specialization are badly suited to the pure visual programming of those early tools but it also makes it increasingly hard to build rounded software engineering teams. While pure visual programming environments have failed, there is a whole cache of similar tools that take the best of visual programming and combine it with text-based coding. Whereas visual programming was “no-code,” these new tools are low-code.
Visual programming held so much promise but unfortunately in its early stages, it came up a little short on those promises. However, they continue to more relevant than ever. Real-world problems demand greater flexibility than visual programming could offer hence it might never be able to take the place of the superior textual programming languages. But low-code platforms are helping to reduce the complexity of coding and make it more accessible for citizen developers. We find in modern software development that VPL is an important part of the sector and will never fade into obscurity.
