about Dataset?

Question

Someone can tell me there is a way to update (insert,delete) my Databsae (SQl Server 2000) after I update my Dataset object ? I know that Dataset is disconnected from Database, so i just know there is only way to update database by using SQLCommand object ( use SQL query or Stored procedures). Thnx for your answers.
