The SQL Data Reader is an object that allows you to read the data that is retrieved from a Data Command. It is refered to as a "fire-hose" connection, because you can only read in one direction (and can't jump back and forth through the Data Reader as you would an array or collection). This video shows several techniques of how to retrieve values and metadata from the Data Reader.
