Hi Experts,

Recently I have got quite a challenging task. I did not have an experience dealing with huge amount of data before. So I'm looking for good solution for it. Basically as a source I have an xml data (200Mb file) it's approximately 50000 objects. I'm planning to use Weblogic as an application server, hibernate as a persistence layer and Oracle. I'm not sure whether hibernate is the right technology for it but I want to give it a go. If you had similar experience before I will appreciate if you can share it with me.

Thank you in advance

If it's xml then it's tagged text and should compress well

You are streaming the data and using hibernate, hibernate probably would not create overhead:

Use SAX parser to parse the elements and create as soon as you find complete data and call hibernate to persist that object

this covers what u need to store the xml directly

http://www.hibernate.org/73.html

or use Ajay-Singh's suggestion and parse the xml and use hibernate to persist the individual objects

Basically I parse an xml data using XMLBeans. After the parsing there are 50000 objects that I need to persist. The only thing I'm concerned about is performance. Do you guys tried to persist 50000 objects?? Is there any performance issues??

Ajay-Singh I appreciate your help. And I will accept your answer. Do you have any figures how long does it take to persist 50000 objects??

It can never meet the plain old jdbc numbers, but it would be somewhere around 50% to 100% more than that.
