When to use what...???

Hi, I'm using VB 2005, WinForms. I have a general quesiton regarding data-sources.

VB.NET offers different options in terms of data-sources such as DataSets, DataTables, DataViews, etc. When should each be used? In other words, why use a DataTable vs. a DataSet, or a DataView vs. a DataTable?

Also, is any one data-source more "flexible" or advantageous in any way in terms of use vs. any of the others?

Thanks for your guidance...

 If you read information from a database, you can store that on a dataset and then use it. You can then use a dataview to filter information.
You can use also datatables but has only one table but, in the other side, is very flexible to work with xml.
It depends of what you need!

Hello


Use DataTable instead of DataSet.

DataTable uses less memory than DataSet.
DataTable is faster than DataSet.
DataTable is simple than using DataSet.
Use DataSet if you have a huge collection of tables.


eq.
Dim da As xSqlDataAdapter
Dim dt As New DataTable
da = New xSqlDataAdapter("select * from xtable", xsqlconn)
da.Fill(dt)


Great is our GOD.
