Workshop Partner
DATESO 2012 workshop proceedings was supported by SoSIReCR project
(CZ1.07/2.4.00/12.0039). The project is co-financed by ESF and Czech state
budget.
SoSIReČR
SOCIAL NETWORK OF COMPUTER SCIENTISTS IN THE REGIONS OF THE CZECH REPUBLIC
The project aims to promote communication and establish cooperation between the Czech IT
communities in academic and corporate sectors. The main output will be a Web portal that will
build a social network of computer scientists., which will differ from the usual social and
professional networks as Facebook or LinkedIn by providing unique tools to search for IT
specialists, to create teams (for joint projects, tenders), and in general to allow cooperation. The
aim of the project activities is to increase the competitiveness of the Czech Republic in the field of
computer science, as well as improvement of the status of IT in the Czech Republic and its
contribution to society.
Personal interconnection of educational and research activities and the cooperation of academic
and applied research are required for high-quality tertiary education and its fruitful cooperation
with industry and Government. From the social network will benefit students and graduates,
scientific personnel, schools, and businesses. It will be possible to search here for a job or an
interesting project, skilled workers or whole teams, even the schools can compare their learning
plans with the situation on the labor market. The social network portal SíťIT will be available for
general public in June, 2012 at https://www.sitit.cz/.
Another component of the project is to support personal meeting of the IT experts in the regions
(both among themselves and with companies), the sharing of experience and the identification of
needs. These are the conferences, regional seminars and workshops, aimed at improving
communication between the academic, corporate and public sector. One of the following activities
are for example Conversations with computer scientists (Hovory s informatiky), organised in the
framework of this project by Institute of Computer Science, Academy of Sciences of the CR.
On the SoSIReČR project cooperate:
Faculty of Mathematics and Physics, Charles University in Prague
Institute of Computer Science, Academy of Sciences of the Czech Republic
Czech Technical University in Prague
The Faculty of Informatics and Statistics, University of Economics, Prague
Higher Vocational School and Technical High School, Šumperk
The social network portal SíťIT will be at disposal at the address https://www.sitit.cz/.
Project (no CZ.07/2.4.00/12.0039) is running in period 01.11.2009 - 31.10.2012.

Preface
DATESO 2012, the international workshop on current trends on Databases, In-
formation Retrieval, Algebraic Specification and Object Oriented Programming,
was held on April 18 – 20, 2012 in Zernov, Rovensko pod Troskami.
The 12th year was organized by Department of Software Engineering MFF
UK Praha, Department of Computer Science and Engineering FEL ČVUT
Praha, Department of Computer Science VŠB-Technical University Ostrava,
and Working group on Computer Science and Society of Czech Society for
Cybernetics and Informatics. The DATESO workshops aim for strengthening
connections between these various areas of informatics, particularly this year,
Sematic Web, semistructured data, social networks, and formal specifications.
The proceedings of DATESO 2012 are also available at DATESO Web site:
http://www.cs.vsb.cz/dateso/2012/ and CEUR Workshop Proceeding site:
http://www.ceur-ws.org/Vol-837/ (ISSN 1613-0073). The Program Commit-
tee selected 14 papers (11 full papers and 3 posters) from 22 submissions, based
on three independent reviews.
We wish to express our sincere thanks to all the authors who submit-
ted papers, the members of the Program Committee, who reviewed them
on the basis of originality, technical quality, and presentation. We are also
thankful to the Organizing Committee and Amphora Research Group (ARG,
http://www.cs.vsb.cz/arg/) represented by Pavel Moravec, for preparation of
workshop proceedings. Special thanks belong to Czech Society for Cybernetics
and Informatics and the SoSiReČR project (Social Network of the Computer
Scientists in the Regions of the Czech Republic) for their support of publishing
this issue.
