Presentation Transcript

  1. 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

  2. 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.

  3. Web Content Management and Grid technology • Navigational graphical query-browsing interface Mavigator for retrieval in an object-oriented database • Implemented 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)

  4. 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).
