Converting the SQL data isn't even the important part.  You have to convert / re-create all of your queries because MongoDB isn't SQL, doesn't run SQL queries.  More info: http://docs.mongodb.org/manual/tutorial/query-documents/

So I think I need to create collection in mongodb which is same as table structure and create  documents and relationship between the documents . pls clarify if that is correct

I think you need to go read up on MongoDB.  It is not at all the same as an SQL database.  This page is a comparison of SQL to MongoDB: http://docs.mongodb.org/manual/reference/sql-comparison/

the philosophy behind using noSQL databases such as MongoDB is that the data needs to be stored in a fashion that makes it easy for consuming applications to read and write therefore reducing latency.

Simply trying to map your RDBMS data to nosql won't work. You need to look at the use cases for your applications.
