This paper introduces the first major release of the bigER modeling tool. bigER offers various features for flexibly specifying and visualizing Entity Relationship (ER) data models. Within the Visual Studio (VS) Code IDE, the tool enables hybrid modeling through a textual editor and a graphical editor to display and modify the textual and graphical ER model, respectively. Both editors are realized with a custom language to specify ER elements and allow multi-notation support (currently Bachman, Chen, Crow’s Foot, Min-Max, and UML). The bigER modeling tool incorporates the Language Server Protocol and is based on web technologies, which makes the tool platform-independent and easily extensible. We present the newest extensions of bigER, i.e., multi-notation support and improved edge routing.
