implementing user interface
The DB-aware controls, for example, grid and others can be linked directly to our datasets. Therefore you no longer need TClientDataSet and TDataSetProvider to display and modify data
|

A multi-table join, stored procedure and union results can be easily edited with TDBXUpdateSQL linked to any eXtension dataset while the standard dbExpress usage requires writing the code
