Research conducted by the Chair of Information Systems PJIIT

  Leader: Prof. Kazimierz Subieta Staff:  11 research and didactic workers (1 Prof, 4 PhD, 6 MSc)  PhD and MSc students (ca.15 PhD + ca.80 MSc)  Research areas:  Databases (object-oriented and Web-oriented)  Distributed systems (Internet, grid technology)  Software engineering  E-learning

Research on databases

 Novel Stack-Based Approach (SBA) to object-oriented and Web-oriented query languages  Stack-Based Query Language, SBQL, several implementations:  XML DOM model, ICONS (5th EC framework), Objectivity/DB, YAOD and ODRA  Prototype object-oriented DBMS YAOD  developed from scratch in Java, client-server, XML oriented, SBQL embedded in Java.

 Prototype OO DBMS ODRA (currently developed)  Porting YAOD to .NET, C#, a fully-fledged database programming language based on SBQL, query optimization, strong typing, metadata management.

Web Content Management and Grid technology

    Navigational graphical query-browsing interface Mavigator for retrieval in an object-oriented database I mplemented for the European project ICONS   Integration of a fast distributed Web index based on the SDDS package (dynamic hashing) Our own approach to data-intensive grid and to P2P CORBA-like, federated databases, updateable database views, query language, enhanced Web Services, integration of distributed, heterogeneous and redundant data/service resources.

Implementation has just started (based on ODRA)

Relationships with software industry

  Several industrial software projects in the past 2002-2004, European Project ICONS (5th Framework)  7 partners (4 academic, 4 industry, Poland, France, Italy, Great Britain, Belgium)  The project has been successfully finished with ready to use software (Intelligent Content Management System)  2004-2005 development of methodology for estimation of software costs for Polkomtel SA, polish mobile phone operator.

 2005, application for a grant in 6th Framework EC Programme (e-Government), the project e-Gov Bus.

 3 academic and 4 industrial institutions, in particular European Microsoft Innovation Center (EMIC).
