3 “the technique of converting records in a relational database into objects in an object-oriented programming environment.” Patrick Connor Linskey and Marc Prud'hommeaux Benefits  Need not to know about database management  ORM is in a language familiar to programmers  Ease of maintenance Used by many companies such as Intuit, IBM, Microsoft, Google, and more.

5  Structure which contains information about the relationship of data items  Is semi-structured data  80% of the web is semi-structure data  Use XPath and XQuery to access in a native XML database

9 A Java library that can store, retrieve and query object data in a native XML database has been an important issue. This tool will offer the efficient way of manipulating XML database in Java programming environment.

10  Hibernate XML, Hyperjaxb, and JaxMe  No feature able to directly convert Java Object to and from XML database  Data are not saved as XML databases but instead as relational DBMS  Selection of technology never intended for use with XML databases  Incomplete manual, feeble code base, and poor control of XML data manipulation

11  Persistence of any Java object into a native XML database  Concise APIs for XML database manipulation  Local databases through the XML:DB API  Persistence API for XML data binding and querying  Support for issuing XPath queries, returning results as typed Java objects

12 Existing Components  Database - we used eXist, an open source native XML database.  XStream – we used this component for serializing Java objects to XML, and vice versa. New Components  JOXM - this was the part we implemented. JOXM includes the code responsible for much of the administrative aspects of the program in general.

14  Our goal to create an XML equivalent to Hibernate was successful  Some possible future work:  Allow users to issue XQuery queries to the database,  XPath interpreter for the Hibernate Query Language (HQL)  Transaction management  Provide support for the XQuery Update Facility (XQUF)
