Working with Delimited Flat Files-target
Review the data in the target table. All looks good here.

We are done, successfully imported and loaded tab delimited flat file to a target table. Here we just used a simple mapping without formatting anything on input data, We may need to do some kind of data validation before we process through the transformation and that we will see in the next post.
