PROJECTS

1.        Created    a       Web-based     demo     (http://www.db.ucsd.edu/objectrank)  of  the ΟbjectRank system, which precomputes the ObjectRank values and returns the most relevant objects for a keyword query. The demo uses the DBLP bibliographic database.

2.        Created a Web-based demo (http://www.db.ucsd.edu/xkeyword/) of the XKeyword system, which operates on top of a commercial Database System and answers keyword queries on the DBLP bibliographic database.

3.        Created Web-based demo (http://www.db.ucsd.edu/PREFER/) for the PREFER system. Also, implemented PREFER as a standalone, user-friendly application, which handles both the server and the client side of the system (available for download at http://www.db.ucsd.edu/PREFER/).

4.        B.S. thesis project. Implementation of a stock market analysis and presentation application that automatically loads data from Web pages and stores   them in a DBMS. Used Oracle Developer and Visual C++ ActiveX technology.
