Patent number: 11954460Abstract: A method and system for developing low-code and no-code software applications in a visual programming environment uses data flow expressions in which processing steps are represented as homoiconic data expression statements recorded in a transaction log that is accessible to developers at all times and that follows ACID rules. Data flow expressions are written in an interface description language for easy readability by non-programmers. An internal replacement language represents the modeled application and produces executable code by applying a target language template, producing executable code in other programming languages without knowing how to code in those languages.Type: GrantFiled: August 20, 2023Date of Patent: April 9, 2024Inventors: Robert G Baker, Jordan Henderson, Michael Cairl
