style="font-family:Calibri;color:black">SQL/XMLis an ANSI and ISO standard that provides support for using XML in the
contextof an SQL database system. Because SQL is the standard language for accessing and managing data stored in
relationaldatabases, it is natural that enterprises and users worldwide need the ability to integrate their XML data
intotheir relational data through the use of SQL facilities.SQL/XML makes it possible to store your XML documents in
yourSQL database, to query those documents using XPath and XQuery, and to "publish" your existing SQL data in the form
ofXML documents.</span><p style="text-align:justify;text-justify:inter-ideograph;background:white"><span
style="font-family:Calibri;color:black">NowadaysXml datatype is generally used to store,manipulate and export data
betweencross-platforms.We intend to implement and XML/SQL query for the postgresql based on XQuery,XPath. Postgresql
8.3implemetns core functionalities for the SQL/XML but the XQuery is still needed to supported. Since XML is
semi-structuredit is flexible to use by other programming languages,reporting web-based applications as well as data
exchangebetween different DBMSs.</span><p

href="http://english.iyte.edu.tr/main_eng.jsp?pageName=main.htm"><spanstyle="color:#551A8B">iztech</span></a> in
turkey.My areas of inetrests are information management, OOP(Object Oriented Programming) and currently bioinformatics.
Ihave been working with a Asistan Professor(<a href="http://jens.allmer.de/"><span style="color:#551A8B">Jens
Allmer</span></a>)in molecular biology genetics department for one year.Firstly, we worked on a protein database <a
href="http://www.2db.de.ms/"><spanstyle="color:#551A8B">2DB</span></a> and we presented the project in <a
href="http://hibit09.ii.metu.edu.tr/"><spanstyle="color:#551A8B">HIBIT09</span></a>organization. The Project  was
“Databasemanagement system independence by amending 2DB with a database access layer”. Currently, I am working on
anotherproject (Kerb) as my senior project which is a general sqeuential task management system intend to reduce the
errorsand increase time saving in biological experiments. We will present this project in <a
href="http://hibit2010.ii.metu.edu.tr/"><spanstyle="color:#551A8B">HIBIT2010</span></a> too. Moreover,I am good at data
structuresand implementations on C. </span><p
