The biggest change from the Delphi world is that you have to consider
that a DataTable is a collection of DataColumns and DataRows. You can
treat a column or row as a unique entity.

DataTables also support primary keys, but not more general indexes that
TClientDataSet is able to support. However, the main reason people use
indexes on TClientDataSet is to give you a certain order for the data.
In ADO.NET, DataViews are helpful to sort and filter data from a
DataTable.

Further, a DataTable can stand alone, or it can live in a bigger
collection called a DataSet. A DataSet adds other features that you
would normally expect in a database: support for multiple tables and
referential integrity between the tables (supported by DataRelations).
