TDataSource is a component that mediates communication between a TDataSet based component that represents the database contents and Data Controls like TDBGrid.
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.
SQLTransaction1.Database := SQLConnection1; SQLQuery1.Transaction := SQLTransaction1; DataSource1.DataSet := SQLQuery1; DBGrid1.DataSource := DataSource1;
