Easy Way to delete bulk data

This question is asked on the blogs too much.

If you have some how uploaded bulk data in to the system and the form doesn't allow you to select all the datab and delete or you assume that deletion may take some time;

Then you can use data migration functionality to delete data easily.

In this case, you create a new data migration header and select "Truncate data" on the newly created header.

Then go on selecting the tables that you want to delete as you are uploading data.

Thats it

This is todays hint :)
