ER Forum, Demo and Posters 2020 was part of the 39th International Conference on Conceptual Modeling (ER 2020), whose overarching theme was Digital Transformation|Exciting Times for Conceptual Modeling. ER 2020 encompasses a broad array of sub-themes such as foundations, data and object management, engineering, business information systems, advanced and cross-disciplinary applications and experiences with conceptual modeling. ER Forum, Demo and Posters 2020 o er a platform for presenting and discussing novel research ideas addressing any of the ER conference topics as well as new emerging topics related to conceptual modeling, where innovation prevailed over maturity. The main goal was to facilitate the interaction, discussion and exchange of ideas among presenters and participants. ER Forum, Demo and Posters 2020 accepted four types of submissions: full research papers (14 pages), short research papers (8 pages), tool demonstrations and posters. We received 28 submissions, whereas 9 full papers, 4 short papers and 5 demos were accepted. During the peer-review process, each submission received three reviews by an international program committee. ER 2020 was planned to be held in Vienna, Austria, on November 3{6, 2020. However, due to the COVID pandemic, the whole conference and satellite events were switched to a virtual format at the same dates. Presentation of the publications has started with a Madness-Show including all contributions since the rst ER Forum in 2017. Due to the virtual format, the Madness-Show was performed as a compilation of 1-minute videos. This was followed by live presentations of demonstrations and research papers. We would like to thank the international program committee members for their reviews and discussions about the submissions. We especially thank the authors who took the time to carefully write up the results of their research and submit papers for consideration. Finally, we would like to thank the other members of the Organizing Committee of the ER 2020 for their support and cooperation.
