Complex event processing typically requires studying the query language of a CEP engine and writing the required queries by hand. This is an overwhelming task, and requires extensive prior knowledge. In addition to that, the coding process becomes complicated with complex requirements and multiple steps involved. Therefore a visual editor which lets users construct CEP programs visually is a highly desirable addition to the CEP community. In this paper, we present an approach to creating a Visual Editor for construction of CEP programs.
