I have gone through the procedure of creating n External Content Type and based on that i was able to see an External List. So the data which i was seeing in the sql table was shown in the External List.
So now we have the same data in two different location on in the External List and the other in the SQL Table.
Is it really possible not to create an External List and in a Webpart i can call the External Content Type Methods and display the data.
