Rule composition and decomposition is a hot research topic within the context of model transformation. Mostly, transformation rules are considered as atomic parts of the transformation and rule composition has been the focus of recent research in the model transformation area. In our approach, we consider the transformation operations such as add, delete and update operations as the atomic parts of the transformation and the synthesis of these operations constitutes a single transformation rule. Defining complex and hierarchical source pattern definitions requires approaches and techniques about the composition and decomposition of these operations. In this paper, we discuss the problem statement and present an example case in which operation composition is required.
