I. Introduction
Today, the term low-code/no-code platforms (LCNC) appears in the industry more and more, as well as the concept of citizen developer in which the key/end user, who is definitely non-developer, uses low-code/no-code platforms to create extensions or new business applications suitable for solving needs in everyday activities instead of asking IT department or engagement of third-party companies. Users who can think logically, understand the business needs and understand basic programming structures, using low-code/no-code platforms, can become companies’ key asset [1]. Analytical companies, like Gartner and Forrester, estimate a significant growth rate of their application in the years to come [2], [3], [4].
