ICDT '97 will take
place in Delphi, Greece, on January 8-10, 1997. ICDT  is a biannual
international  conference on theoretical aspects of databases
and a forum for communicating research advances on the principles of database sy
stems.
Previous ICDT conferences were held in Rome (1986), Bruges (1988), Paris
(1990), Berlin (1992), and Prague (1995).
Since 1992, ICDT has been merged
with  the Symposium on Mathematical Fundamentals of Database Systems (MFDBS),
another series of conferences on theoretical aspects of database systems that
was initiated in Dresden (1987), and continued in Visegrad (1989) and Rostock
(1991).\\

\noindent
{\bf Topics:}
ICDT aims to attract papers of high quality, describing original ideas
and new results on theoretical aspects of all forms of databases. Major themes t
o be
covered include, but are not limited to:

%\medskip
{\small
\begin {tabbing}
database programming languages \quad \=distributed and heterogeneous
databases \quad \=\kill
active database systems \>
complex objects \>
complexity and optimization \\
concurrency control and recovery \>
data models and design theory \>
data structures and algorithms for databases\\
database programming languages \>
deductive databases  and logic \>
dependencies and constraints \\
distributed and parallel databases \>
fundamentals of security and privacy\>
heterogeneous databases\\
incomplete information \>
multimedia information systems \>
nonmonotonic reasoning \\
object-oriented databases \>
query evaluation and optimization \>
query languages \\
spatial and temporal data\>
transaction management\>
updates
\end{tabbing}}
%\medskip
\noindent
{\bf Submissions:}
Authors are invited to submit 8 copies of a full conference paper
(which might be an extended abstract where proofs are only sketched)
of about 5000 words (10 typed pages in no less than 11-point font) by
June 13, 1996, to one of the program
co-chairs:

\noindent
The cover page of each paper should contain the address, e-mail, fax and phone
numbers of the contacting  author, as well as a short abstract.
The results presented in the paper must be unpublished and not submitted for
publication elsewhere, including the proceedings of other conferences or
workshops. One author of each accepted paper will be expected to present the
paper at the conference.
As in the past, it is planned that the proceedings of ICDT'97 will be
published by Springer-Verlag in the Lecture Notes in Computer Science series,
 and  will be available at the conference.
