I Wasnt To Learn All The Possible Ways Of Accessing Data In ASP .net 2.0

Hello.
I would like to learn all the possible ways that we can access and modify data in ASP .net 2.0 programmatically.
for example one way would be like this:

 StringBuilder sql = new StringBuilder();
sql.Append(" SELECT *");        //count the total number of records
sql.Append(" FROM dbo.tblJobTitle ");  

//get the connection string from web services
string strConnection = new sqlconnection.SQLConnection().GetSQLConnectString(sqlconnection.SQLDSN.SCIC);

//Use the Microsoft.practices SqlDatabase object to execute our sql.
SqlDatabase SqlHelper = new SqlDatabase(strConnection);
SqlDataReader reader = (SqlDataReader)SqlHelper.ExecuteReader(CommandType.Text, sql.ToString());

the i can loop through reader and get the data OR I can create a DataSet like this: 
SqlDatabase db = new SqlDatabase(strConnection);

DbCommand dbCommand = db.GetSqlStringCommand(sql.ToString());

DataSet dst = db.ExecuteDataSet(dbCommand);

I want to know if there is a comprehensive book explainaning all these possible ways to access and modify data using C#  under ASP .net 2.0
I really really apreciate this.
Thank you very much.
