| 1 | 1 | **TDataSource**  is a component that mediates communication between a [[TDataSet]] based component that represents the database contents and Data Controls like [[TDBGrid]]. | |
| 2 | 2 | ||
| 3 | 3 | Typically, a `TDataSource` contains a field 'DataSet' that connects to a [[TSQLQuery]] or other `TDataSet` descendant. The DataSource should connect to the 'DataSource' field of a TDBGrid or other Data Control component. | |
