RDB schema conversion to XML Schema

Question

Hi,

We are developing a project, with the concept of database virtualization, i.e considering more than one database as a single datbase so that in user view only one database exists for that we need to prepare common XML schema. So we need reading the schema information from the RDB and converting into XML. The RDB includes 'table name', 'fieldnames', and 'constraints(i.e primary key)' etc.
