CRUD operation with multiple tables using DAL and BAL (No EF

Question

I was looking for tutorial which implements the raw programming in C# asp.net CRUD operations with multiple tables. My tables will be like below holding the one-to-many and many-to-many relations .

 

 

I don't want to use Entity Framework but want to use the three tired architecture with separate DAL library and BAL library to perform all operations as below from asp.net mvc web pages.

-Performing all student,Tutor & Subjects CRUD operations

- In creating courses, need to select Tutor and Subject from dropdownlist

-Provide the other CRUD operations on courses

-Finally CRUD operations on the enrollment

 

I DIDN'T FIND ANY TUTORIAL WHICH SHOWS THIS BASIC CRUD OPERATIONS WITHOUT USING EF.
