The mission of the PJIIT
• Train specialists who will be able to work creatively in
different areas of computer science which are especially
important for the development of the country.
• Conduct scientific research into the developments and
design of new information technologies.
• Establish and strengthen international ties for the
technological cooperation with special emphasis put on
the benefits of combining the Japanese team work culture
and highly advanced technology with the Polish tradition
in science and individualism.

– Object-oriented database management system based on StackBased Approach (SBA) and Stack-Based Query Language (SBQL)
– Client/server
– Imperative constructs, modules, procedures, classes, types,
methods, static inheritance
– Updateable OO database views
– Strong typing and query optimization
– Importers/exporters from/to external sources

European Projects
• European Project eGov Bus
– A dynamically adaptable information system supporting life events
experienced by the citizen or business serviced by European
government organizations.
– Integration of distributed, heterogeneous, redundant and fragmented
resources for eGov applications.
– 8 European partners, Jan 2006 - Dec 2007, total budget 4 M€
• European Project VIDE
– The UML-compliant action language VIDE to be researched,
developed, evaluated and disseminated during the project will enable
fully visual prototyping, programming, debugging and documenting of
future applications.
– Implementation of OMG MDA, visual programming.
– 10 European partners, July 2006 – Dec 2008, total budget 4 M€

Dec. 2006
SBQL in the eGov Bus project
• SBQL as embedded QL for application programming in Java.
• SBQL as a self-contained DBPL for application programming.
• SBQL updateable views will play the following roles:
– As mediators that virtually convert a local data and service resource
to the shape that is required by the canonical model.
– As integrators that virtually fuse fragmented collections residing on
different servers, resolve heterogeneities, remove redundancies, join
fragmented remote services into the form of a procedure (c.f. life
events) and (if necessary) equip some remote objects into new classes
and methods.
– As customizers that adapt the data that are seen through the canonical
model to the need of particular end user applications and/or to
particular users.

SBQL in the VIDE project
• SBQL queries will occur explicitly as VIDE language constructs
on the MDA PIM level
– depicted visually in the visual version of the language code.
• SBQL queries will address directly UML-like class diagrams.
• SBQL queries will be components of visual programming
graphical metaphors.
• The VIDE language will have both visual and textual syntax
with no losses in the automated conversion between the two.
• The programmer will have the freedom of choice to edit either
the visual or the textual code.
