Kavitha,
If i understand your requirements correctly, you have the DATA and need to load this data in the tables and create indexes on them. And you also need some scripts for the IMPORT/EXPORT of the data.

And also you need the DATABASE, what do u actually mean by new DATABASE,, is the database is available for you or you need to create one ???

Would you be more clear of your requirements.. Anyway, for all your requirements, you can look at
http://metalkink.oracle.com
or
tahiti.oracle.com and do a search of your requirements.

May be they help you best for the time being
