The 3rd Workshop on the Databases Worldwide


The 3rd Workshop on the Databases Worldwide will be held on the main days of the 30th FRUCT conference on October 28-29, 2021. Despite COVID-19, we keep on collecting submissions and plan, but the workshop will be held as a mixed of onsite and online participation, i.e., distant participation is welcome. We welcome you to submit your papers.


Call for papers, posters and demos

The workshop aims to provide complex discussion capability about the current problems and trends in the database systems. Over the years, it is evident, that the amount of the data was significantly changed. Almost every system, every device produces data that needs to be processed, evaluated, stored, and analyzed, with an emphasis on quality, reliability, temporality, and spatial determination. Complex decision making is possible only if the particular data are available, mostly produced by the database environment. This workshop will be concerned with the architecture of individual systems and approaches, performance optimization, transformation techniques, indexes, reliability of the processed values, as well as analytics. It will highlight performance, limitations, and new perspectives dealing with the data, mostly in cloud environment. Data retrieval, indexing process, and performance can really become strong issues if the amount of data is rapidly changed. Scalability and data distribution techniques will be concerned by the workshop, as well. Currently, each of us feels the importance and necessity of moving to an online environment where data efficiency is an essential element. We are looking forward to proposing the environment under the FRUCT organization and conferences to provide valuable contributions and discussions. 

The topics of interest include, but are not limited to, the following areas:

  • relational databases, architecture enhancements, 
  • autonomous databases in cloud, cloud computing, data driven applications and systems,
  • blockchain,
  • SQL tuning, 
  • spatial databases, 
  • temporal databases, 
  • non-relational approaches, indexing, and transformations, 
  • reliability of the data, 
  • databases and ad-hoc networks, 
  • cloud database environment, 
  • indexing in multiple database structures, 
  • data distribution techniques, 
  • workload management, 
  • database efficiency, 
  • database analytics, warehouses, marts, 
  • optimization in databases, 
  • complex data driven database applications in education, health-care systems, and transportation, 
  • usage of complex sensorial networks supervised by the databases in the industry and mobile environment, 
  • monitoring database, 
  • machine learning and artificial intelligent in database systems.

The event is being run alongside the 30th IEEE FRUCT an interdisciplinary conference. The participants to the workshop will have access to all the sessions of the FRUCT conference.

For your submissions please use the paper templates MS Word and LaTeX.
