What is the difference between direct and representative democracy?

Direct democracy means that every voter has the opportunity to make the final decision on an issue, for example in a referendum you are asked one question on a political decision.Wherass representative democracy is where you vote for a person that you believe will best represent your views. Therefore they vote on a variety of issues in parliament and your decision making power is delegated to them. So direct is you personally voting on every decision but representative is electing someone to do that for you.
