WikiXMLDB

Start of project – 2010. End of project - 2010.

This project provides a way of querying Wikipedia with XQuery. We have parsed Wikipedia content into well-structured XML representation, loaded it into Sedna XML database and implemented an XQuery Web interface.

Content and Knowledge Management Framework

Start of project – 2008. End of project - 2009. Customer - Great Russian Encyclopedia Publishing Company.

The framework provides full-life cycle content and knowledge management services that are used to develop advanced information products based on encyclopedias and references. Our Sedna XML Database is the core component of the framework. It provides a single-sourcing publishing, powerful content reuse, superior search & navigation, and great flexibility in information products customization.

TweetSieve

Start of project – 2008. End of project - 2008.

TweetSieve – a system that allows obtaining news on any given subject by sifting the Twitter stream. Our work is related to frequecy-based analysis applied to blogs, but higher latency and lower coverage in blogs makes the analysis less effective than in case of micro-blogs.

BizQuery - XML-based Virtual Data Integration System

Start of project – 2000. End of project - 2003.

BizQuery is a package of servers and tools for application development in presence of heterogeneous data sources. The main component of the package is BizQuery Integration Server, which is for querying across multiple heterogeneous databases in XQuery language. BizQuery Integration Server supports the notion of global schema defined in XML.

ISP ORB

Start of project – 1997. End of project - 1998.

ISP C++ ORB is a free tool for development of distributed software. ORB plays the role of communicator between different components of distributed applications which can run on the different platforms. ISP C++ ORB is compliant with OMG Common Object Request Broker Architecture 2.0 (CORBA 2.0) standard.

GNU SQL Server

Start of project – 1996. End of project - 1999.

GNU SQL Server is a free portable multi-user relational database management system. It supports the full SQL89 dialect and has some extensions from SQL92. GNU SQL Server implements highly isolated transactions, and static & dynamic query compilation. Both, client & server sides of the system work on Unix-like systems. Client/server interaction is based on an RPC mechanism. The server sub processes facility requires message passing and memory sharing facilities.
