    ER Forum, Demo and Posters 2020 was part of the 39th International Con-
ference on Conceptual Modeling (ER 2020), whose overarching theme was Digi-
tal Transformation—Exciting Times for Conceptual Modeling. ER 2020 encom-
passes a broad array of sub-themes such as foundations, data and object manage-
ment, engineering, business information systems, advanced and cross-disciplinary
applications and experiences with conceptual modeling.
    ER Forum, Demo and Posters 2020 offer a platform for presenting and dis-
cussing novel research ideas addressing any of the ER conference topics as well
as new emerging topics related to conceptual modeling, where innovation pre-
vailed 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 first 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.
