Does InnoDB run bugless if PK is FK of same table relating to PK of an other table ?

[Baron Muenchhausen]

Question: Will the following Part of my DataBase run bugless with InnoDB of MySQL?? Please consider all PK-FK relations!!

PK:PrimaryKey FK:ForeignKey PKa belongs to FKa

table BorrowingProcesses:
PK[ FKBarcode, DateOfIssue ], FKCustomerID, DesiredDateOfRefund, DateOfRefund, FKaBorrowerStaffID, FKaTakeBackStaffID, Paid

table Customers:
PKCustomerID, FKFirstName, LastName, Email, PhoneNumber, FK[ FKCountryID,Zipcode ], Street, HouseNumber

table Companies:
PKCompany, POBox, FKCustomerID

table AcademicDegrees:
PK&FKCustomerID, AcademicDegree

table Staff:
PKaStaffID, StaffFirstName, StaffLastName, Password[encrypted]

all other relations between tables are unproblematic 1:mc-relations
