Hi there ! Is there a comprehensive data modelling tool that can
convert logical data model into physical data model (database) of
your
choice (Oracle / SQL Server / DB2 etc). If yes than can this tool be
relied upon for re-engineering the physical database. If yes then
what
happens to the data that and how is the data managed during the
reengineering process.

I have not checked either url recently but both the following web sites used to have references to ERD tools:

http://www.databaseanswers.org/modelling_tools.htm

http://savage.net.au/Ron/html/drawing-tools.html

Some of the developers I work with have used CA Erwin and had a good opinion of it.

You need to distinguish schema information and data.  Modeling tools
deal with the schema information.

If you want to know more you can eg. look here
