We at International Institute of Information Technology (IIIT) Hyderabad, India, have extended the Postgres database<br
/>systemwith the skyline operation. For this work, we were guided by our Prof. Kamalakar Karlapalem<br /> (<a
href="http://www.iiit.ac.in/~kamal/">http://www.iiit.ac.in/~kamal/</a>).<br/><br />We have extended SQL 'SELECT' clause
byan optional 'SKYLINE OF' clause in<br />version 8.0.3. The changes are done in parser, transformation, <br
/>planner/optimizer(a bit) and executor stages. For its execution, two novel algorithms - BNL (Block Nested Loop) and
SFS<br/>(Sort Filter Skyline) - are also implemented.<br /><br />Can this piece of work contribute to PostgreSQL? If
yes,then we'll send out a detailed report of this project including changes <br />made, issues involved/need to be
solved,limitations, future work, and the source code etc.<br /><br />Thanks very much.<br /><br />Regards,<br
/>Nikita<br/>Ranbeer<br /><br />--<br /><a
