.Net vs SSIS: What should SSIS be used for?

Question

If I have the option of using .Net and can do data transformations just fine in .Net, when would I need SSIS? Is there a certain task

Answer 1

I think main advantage is defining the entire programming construct visually. Any one look at the SSIS package is it pretty much self explainer. The tight integration with the SSIS with SQL allows you to be part of SQL for back up scheduling and huge plus.

As every one explained if you are doing the lot of data manipulation it is good tool. It is free if you have SQL you all set to go and very easy to learn with VS 2008 BIDS
