I want to set-up log shipping but need a way of simulating database activity.

What I am wanting to do is simulate x number of transactions per second - essentially to prove the theory to my boss - so he can see it in action..

I'm not very hot on SQl queries hence me asking what I could do to achive this. Ideally some process I can run that pumps data into say the Northwind database - something that is really going to give log shipping a run for it's money!!
