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 , 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) 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).
