Design Of A Process

I'm going to design a web page for students parking permit application.I'm new to asp.net, I have a process in mind doing it like this:

The form asks student to choose a permit type, then fill in  applicant info, like name, grade, vehicle info, student may have 2 vehicles, and payment method, check or credit card,

I plan to create 3 tables like tblPermit, tblapplicant, tblVehicle.After the students fill in the form, click submit button, I pass the values and call a stored procedure, some thing like this.Dim Cmd As New Data.SqlClient.SqlCommand(MySQL, MyConn)

Cmd.CommandType = Data.CommandType.StoredProcedure

Then in the stored proceudre,  I will do :

Begin

insert into Permit table, then get permitID, by using something like this:Select @PermitID=@@Identity

Then insert into Student table, then use

Select @StudentID=@@Identity

Then insert into vehicle table.

All the above 3 processes I put it in begin, end--So that they will not messed up with other applicants data.

I think begin...end is one transaction.

SO am I doing correctly this way?  Thanks
