DataView is just equivalent to a Table image, you can modify, add, delete data inside.
DataSet can contain multiple TABLE, that is, multiple DataView can be included.
In fact, in general, use DataView and use DataSet, but if you use Dataset, you may have a long way.
Such as:
DataView1.count
Be equivalent to
Dataset1.tables (0) .defaultview.count

DataSet From a sense that it can be regarded as the structure of the database, you can put multiple DataTable in a DataSet, you can have multiple DataView in each DataTable, not only this, you can also set DataTable. Relationships and constraints, as well as multiple DataView of a DataTable, below is the general architecture of DataSet:
DataSet
------ TABLES
| ------- Columns
| ------- Rows
| ------- Contraints
------ RELATIONS

A DataSet can contain a lot of DataTable, each DATATABLE contains 0 to multiple data records. DataTable has a DefaultView reflects the "original face" (possibly sorted) of the data taken from the database from a database. The biggest use of DataView is to achieve a perspective of a DataTable, which is useful for Data Binding. Simply put is that DataView implements various sort according to DataTable existing data (of course, DataTable raw data has been sorted in some standard) and data filtering (displays or hide certain data).

So many people are talking about DataSet, I add DataView,
DataView is to easily filter, filter, search, and operate the class of data items, which does not destroy the data of the tablet, each Table DEFAULTVIEW is equivalent to the DataView when the filter criteria is null.

DataView is a data window of DataTable. You can see the requirements that meet the requirements through this window, and you can even change the data you see.
In fact, it is a kind of document of Document / View.

DataSet is quite with Database (with Table Collection, Constraint.etc;)
DataView is quite with views (there can be multiple, depending on different conditions)
