DataAdapter serves as a bridge between a System.Data.DataSet and a TDataSet component (data source) for retrieving and saving data.
DataAdapter serves as a bridge between a System.Data.DataSet and a TDataSet component (data source) for retrieving and saving data. DataAdapter provides this bridge by mapping DADataAdapter.Fill, which changes the data in the System.Data.DataSet to match the data in the data source, and DADataAdapter.Update, which changes the data in the data source to match the data in the System.Data.DataSet.
