Nowadays, there are people working within the IT-industry without any major knowledge in programming. Some of them sometimes need to make changes that currently only can be done in the actual code. This project is about finding the best way for non-programmers to make changes in a data-model without having to change the code. The project is divided into three parts where the first two is about finding different ways to solve this problem and then evaluate them through expert evaluation and based on relevant theory. The third part is about taking the result from part one and two and develop it. The third part ends with user-tests and follow-up interviews with 12 test-participants. In this part, also programmers will participate to get a complete overview of all the intended user’s experience. The result is that a graphical concept is to be preferred for users with minor/without programming experience. For programmers, it is harder to tell which concept is best and a more extensive investigation probably has to be done to get a fair result. These conclusions are based on the results from the conducted tests/interviews together with available external theory. The results could be improved with more users and more extensive tests. Worth mentioning is since all users are individuals, different concepts suit different persons and what suits one user best might not suit another at all, despite background as programmer or non-programmer.
