Today I did two things. One is the programming of the windows form., including the static page of the form and the responding to some actions. This part is before the launch.

And in the afternoon I try the access to the database use data provider for sql server.

Now I found a really good book published by Tshinghua Univ. And I know many things that troubles me.

The point I must know:

1. ADO.NET is the Mid-software for DB development, it is based on the .net framework..It include some classes and some namepaces provided by .net Framework.

The namespaces are System.Data.SqlClient, System.Data.OracleClient,OLEB,ODBC.

2. Dataset is a small DB.It is a very important part in the ADO.Net cuz it is like a buffer in the local.

3. There is also a layer structure here. The Dataset is above the Dataprovider layer, which is responsible to access the database.

4. The core class in the Data Provider is connection,command,parameter, datareader, dataadapter and so on..
