What are the used UML diagrams? A Preliminary Survey.

Abstract. UML is a large notation offering many diagrams and a large set of constructs for each of them covering any possible modelling need. As a result its specification is a huge book, its metamodel is large, and defining/understanding its static and dynamic semantics is difficult. These features have a negative impact on the perception of the UML and lead in some cases to replace it by ad-hoc lean and simple DSLs. Thus, the following question arises: which are the most/less used UML diagrams/constructs? We would like to answer to this question by means of a survey, trying to detect which parts of the UML are the most used. To see how much a diagram is used we preliminarily investigate books, courses/tutorials, and tools covering UML. The less used diagrams will be then analysed to understand the reasons of their low usage. 1
