TMWTable component is much like standard Delphi TTable or TQuery components. TMWTable is used as an interface between data and your program or visual interface.

TMWTable is a TDataSet descendent so you can use it with data-aware controls such as TDBEdit and TDBGrid. Just like you use TQuery or TTable.

TMWTable is an interface that present MidWare communication buffer (TMWBuffer component) as a standard Delphi data table. It let you navigate thru all records and fields. You can and locate data, insert, delete or edit data. TMWTable has no storage for data: all data is stored in TMWBuffer component.

TMWTable has no knowledge of table structure. You must specify it using FieldLayout property. You can fill this property at design time if you know what it will be at runtime, or you may fill it at runtime once you know the value. The value may be known at runtime because your client application query the application server for field layout. You may also sent field layout in first record in result set, feed it to the property and then delete it from result set.
