n is there any tool in vb.net to directly map the data to the database

Can you please elaborate more ???

The things I understood from your question now is that:
You have a database, named "datacs" which have a table "Student" that have following attributes:
name->name of student
sem->Semister
rollno->student roll no
pho1-> ?????

Please explain:
>>>>roll no i have entered now i have to enter the marks in pho1 for all rol no how...........

>>>>is there any tool in vb.net to directly map the data to the database
Are you talking about Insertion, updation of records ???
