BCS to save data into different SQL Table

Hi,

There is a requirement to save data back to different table instead of original table that is retrieved using BCS whenever there is any CRUD operation is performed. Any idea whether it’s possible to saved data in different table.

OR

Is this possible to get data from XML file rather than SQL Table using BCS ? User is having XML file located lets say on file system. Using BCS or any other method, is this possible to show XML file data into SP list and perform CRUD operation on this data?

Any help will be highly appreciated.
