Import and export the bulk data

Hi 
I created a duplicate application .i am able to duplicate the structure and not data .You people replied that there is a option to import and export the table data.
But    I have so many database  tables in my application . Now  i  am able to import and export single table data at a time. 
can i have the option to importing and exporting the bulk data(like more than  10 tables data at a time ) ?.


Please Help me out
