1) I have listed down the changes in the word document.
2) I attached the latest solution with the GUI changes. But I did not do any changes to the code.
3) Also attached is a sample. You will notice that there are 2 project, LibDataAccess & LibBusiness. LibBusiness is the business logic while the LibDataAccess is the connection to the database.
Note that there is should be no more hard coded of database in the code.
