Welcome Letter by the Editor
Dott. Roberto Zicari is Full Professor of Database and Information Systems at Frankfurt University and
representative of the OMG in Europe. Previously,
Zicari served as associate professor at Politecnico di Milano, Italy; Visiting scientist
at IBM Almaden Research Center, USA, and the University of California at Berkeley,
USA; Visiting professor at EPFL in Lausanne, Switzerland, at the National University
of Mexico City, Mexico and at the Copenhagen Business School.
The idea of this Web portal originated during a meeting I had with Christof Wittig
of db4objects in June 2005. Christof asked me if I was interested to create an Educational
Program to help promoting and further use of object databases for the researchers
and developers communities.
I was intrigued by this idea. My interest in Object Technology in general and Object
Databases in particular is rooted back in the mid 80s. First at IBM Research Center
in Almaden , San Jose in 1985 and 1986 , where I worked with colleagues at the definition
of an extension of the relational data model to accommodate complex data structures,
and then starting in 1989 for a few years where I had the privilege to join in
the design team of the Gip Altair project in Paris later to become O2, producer
of one of the first object database product in the world, and to the best of my
knowledge the first commercial object database product made in Europe.
For me as a young researcher at that time, it was an incredible challenge. I had
the possibilities to see my research ideas turned into reality and incorporated
into a product that was supposed to replace the existing relational database systems
on the market...
This did not happen.
Years later, relational database systems are still very well established, and only
a few commercial companies offer object database systems.
So why embarking into this project? At first glance it looks like a challenge, not
obvious, and perhaps this is one of the reasons why I like this project, but there
are important factors that made me think and convince to accept to conduct this
First, Object Technology is main stream since years now. Both for modeling, UML,
and for programming environments, Java, C#. Code generation, MDA, patterns, platforms,
objects are all over. This is very different than in the mid 80s early 90s when
object modelers and developers were early adopters.
Second, the Open Source community clearly demonstrated the feasibility of their
ideas that Open Source is more than simply a number of talented developers around
the world cooperating together, but it is also a viable business model. Examples
of these are in the operating systems obviously Linux, and more recently in the
database market, MySQL.
Third, interesting new markets are shaping up, such as the Embedded market. This
could prove to be an ideal place for technologies such as object databases to bridge
that gap between all these objects around and databases..
Funny enough, the gap between objects on one side and databases on the other side
is still a problem, as it was several years ago. The important difference is that
now million of objects have been deployed in a variety of production solutions and
products around the world, not any more by a number of early adopters.
With this program I want to create a resource on the Web where researchers and developers
can freely download technical information, teaching material and when possible software
to help them in their work. Teaching at graduate or undergraduate level, conducting
research, developing software for a commercial product, developing software for
an open source project are all good examples of this.
This place is not exclusive, it is a shareable resource. I am honored that a number
of friends and colleagues around the world have agreed to contribute to this project.
They are all listed under the Expert Corners. A big thank you to all of them!
I also would like to thank our corporate sponsors for their support that made this
I wish you an enjoyable visit to ODBMS.ORG and I hope this will be useful for your

P.S.2 The world of data management is changing quickly! Big Data, Analytical data platforms, Scalable Cloud platforms,
NoSQL data stores, NewSQL databases, Object databases, Object-relational bindings, Graph data stores, Service platforms, and new
approaches to concurrency control are all becoming hot topics both in industry and academia.
ODBMS.ORG offers educational resources in all of these new areas.
