CoMoNoS 2021:

2nd Workshop on Conceptual Modeling for NoSQL Data Stores

Co-located with ER 2021


The objective of the half-day workshop CoMoNoS is to explore opportunities for conceptual modeling, addressing real-world problems that arise with NoSQL data stores (like MongoDB, Couchbase, Cassandra, or Neo4j). In designing an application backed by a NoSQL data store, developers face specific challenges that match the strengths of the ER community.

The purpose of this workshop is to grow a community of researchers and industry practitioners working on conceptual modeling for NoSQL data stores. With this workshop, we hope to provide the necessary breeding ground: We are convinced that practitioners will ultimately benefit from the experience of the ER research community. At the same time, we want to provide a forum for researchers to learn about the actual pain points faced by practitioners.

Research Topics

In the context of conceptual modeling for NoSQL data stores, the scope of the workshop includes, but is not limited to the following topics:

  • Data modeling for schema-flexible or schema-free NoSQL data stores, in-cluding graph databases

  • Agile modeling

  • Modeling for DevOps

  • Data model reverse engineering (schema extraction)

  • Graph matching and graph transformation

  • Unified data modeling for polystores

  • Metamodeling

  • Data model evolution

  • Visualization of data models and data instances

  • Modeling and concurrency control

  • Modeling sharding and replication strategies

  • Modeling for query optimization

  • Process mining

  • Empirical studies and real-world use cases

  • Migrating software architectures to NoSQL data store

Important Dates

Workshop papers submission: July 16, 2021 June 16 (Deadlines extended)

Workshop papers notification: August 6, 2021 July 15

Final (camera-ready) version of papers: August 20, July 31

Conference dates: October 18-21, 2021


The limit for submitted papers (as well as for final, camera-ready papers) is 10 pages. Short papers have a limit of 6 pages.

Authors should consult Springer's authors' guidelines and use their proceedings templates, either for LaTeX or for Word for the preparation of their papers. Springer encourages authors to include their ORCIDs in their papers. In addition, the corresponding author of each paper, acting on behalf of all of the authors of that paper, must complete and sign a Consent-to-Publish form (Link will be added). The corresponding author signing the copyright form should match the corresponding author marked on the paper. Once the files have been sent to Springer, changes relating to the authorship of the papers cannot be made.

All submissions will be reviewed in a single-blind manner. All accepted papers will be made available as proceedings published by Springer.

Manuscripts not submitted in the LNCS style or exceeding the page limit will not be reviewed and automatically rejected.

Submission is done through EasyChair:
