create database for OTA messages from XSDs (persisting OTA messages)

I have to tackle a project with OTA (open travel alliance) messages. These xml messages have huge xsd s, and I am trying to find a way to resemble them in a database schema in an object relational manner, most probably PostgreSQL or MySQL.

So can anyone direct me to any technique that can help me, either in creating class model开发者_开发知识库s ( preferably Java ) out of xsd s and creating a storage for them in a db?

Any help would be appreciated, thanks in advance.

I would try JAXB 2.x, HyperJAXB2 (http://java.net/projects/hyperjaxb2/) or HyperJAXB3.
