The Hellenic Data Management Symposium (HDMS) is the annual forum for the Greek database community to present and discuss recent advances for data-intensive applications. The 17th HDMS will be held between July 8-9, 2019 in Athens, Greece.

In addition to state-of-the-art research from Greek researchers inside and outside of Greece, for the first time this year we will open the meeting to the Greek startup community. We have invited successful startups from Greek founders as well as successful Greek VCs to participate in the conference with presentations and posters in a dedicated “Greek startups” session and there will also be an entrepreneurship panel. Our current list of startups and VCs includes:,,,,,

We invite submissions in the following three tracks:
(A) Research, (B) Working Ideas, and (C) Demos.

Topics of interest include but are not limited to:

Core database technologies (e.g., query processing and optimization, storage and indexing, database concurrency control, OLTP and OLAP processing).

Models and languages for the management of data (e.g., XML, RDF, probabilistic databases, meta-data management, multi-media, graph data management).

NoSQL and Cloud technologies (e.g., storage, scalability)

Techniques for high performance and scalability in the management of data (e.g., distributed data processing, hardware accelerators, new hardware technologies).

Emerging data management architectures (e.g., data stream management, peer-to-peer systems, mobile data management, blockchain).

Confluence of data management with: information retrieval, knowledge management, natural language processing, and data mining.

Data management applications (e.g., geographical information systems, data warehouses, social networks, scientific databases, IoT, crowd sourcing).

Other aspects of modern information systems (e.g., security, privacy, user interfaces, energy use minimization).

Τhe following evaluation principles will apply

Submissions recently accepted at top international conferences or journals are automatically accepted. Examples include SIGMOD, VLDB, PODS, ICDE, EDBT, and SIGIR. Each submission should include the DOI link of the original paper.

The Working Ideas track accepts original work, ongoing work, and position/vision statements. Authors should submit a 1 page PDF in ACM SIGMOD format. Submissions will be reviewed by the PC and chosen for presentation or poster.

This track accepts demonstrations of innovative data-intensive applications, systems, algorithms, etc. Authors should submit a 1 page PDF in ACM SIGMOD format. Submissions will be reviewed by the PC. If submitting an already published demonstration at a top conference, only the DOI is needed (and it will be an automatic accept).

Conference Format:

The conference format will be optimized for interactivity. We will have few long talks and many shorter talks (10 minutes) and posters.

With generous support from Oracle and IBM we have the opportunity to support a number of students this year at HDMS with a free registration (worth 100 Euros for each student). Students chosen for the award will also have the opportunity to meet in person with Oracle and IBM representatives, apply for positions, and go through interview screenings right at the conference site if they wish to do so.

The application for each student is through the following form (link) and should take a few minutes only.

The application deadline is on the morning of June 15 (1pm Athens).


The idea of the conference was conceived by Timos Sellis, Paris Kanellakis and Yannis Ioannidis at SIGMOD/PODS 1994. Many years followed, after Paris had passed away and Yannis returned to Greece and put the idea in motion with Timos. General chair for the first HDMS was Yannis Theodoridis, while Panos Chrysanthis was an enthusiastic and faithful supporter from the very beginning.
