The Hellenic Data Management Symposium (HDMS) is the annual forum for the Greek database community to present and discuss recent advances in the Data Management (DM) field. The 20th HDMS will be held between July 2-3, 2026 in Athens, Greece.
The program will include academic and industry talks, keynotes, panels, research poster sessions, demos, student poster sessions, and other social activities. HDMS does not produce formal proceedings and encourages researchers to submit and present work that has recently appeared in other venues.
This year we plan to have some sessions in English to be inclusive with the foreign students that are part of the Greek database community, accommodate our non greek-speaking participants in general, and enrich our program. So if you can only present in English, you are still very welcome to submit your work.
To help the Greek community form a consistent corpus of relevant terminology, all accepted papers, must be accompanied by (i) title and (ii) abstract in GREEK. This information is NOT required for submission.
Submissions must be submitted electronically in PDF to: https://cmt3.research.microsoft.com/HDMS2026 (please use the appropriate track based on your submission type)
The Microsoft CMT Service was used for managing the peer-reviewing process for this conference. This service was provided for free by Microsoft and they bore all expenses, including costs for Azure cloud services as well as for software development and support.
We invite submissions to the following two tracks:
(A)
Previously-published peer-reviewed papers (long and short papers)
(B) Unpublished papers and abstracts
Specifically:
All submissions in this category will be automatically accepted after light review (to confirm they satisfy the track requirements) for full, short, or poster presentation, depending on program time constraints. Authors will be asked to enter their preference regarding presentation type in the submission form, but we may not be able to satisfy all requests.
Core database technologies (e.g., query processing and optimization, storage and indexing, database concurrency control, OLTP and OLAP processing).
Non-traditional data management architectures (e.g., data stream management, cloud data management, peer-to-peer systems, mobile data management, blockchain databases).
Data management applications (e.g., geographical information systems, data warehouses, social networks, scientific databases, IoT, crowdsourcing).
Models and languages for the management of data (e.g., XML, RDF, probabilistic databases, meta-data management, multi-media, graph data management).
Techniques for high performance and scalability in the management of data (e.g., distributed data processing, hardware accelerators, new hardware technologies).
Confluence of data management with: information retrieval, knowledge management, natural language processing, and data mining.
Data management and analytics for high-dimensional vectors, including time series, data series, and deep embeddings.
Other aspects of modern information systems (e.g., security, privacy, user interfaces, energy use minimization).
HDMS 2026 will take place in Athens (July 2nd - July 3rd 2026) at the Harokopio University of Athens, Amphitheater G. Karabatzos. Entrance to the Amphitheater is through the ground floor in the main University building.
