If a company is setup in fthe following manner:

COMPANY has many DIVISIONS which has many BRANCHES which has many UNITS and I have 4 tables to represent this:

COMPANY

---

COMPANY_ID (PK)
COMPANY_NAME DIVISION

---

COMPANY_ID (FK)
DIVISION_ID (PK)
DIVISION_NAME BRANCH

---

MINISTRY_ID (FK)
DIVISION_ID (FK)
BRANCH_ID (PK)
BRANCH_NAME UNIT

---

MINISTRY_ID (FK)
DIVISION_ID (FK)
BRANCH_ID (FK)
UNIT_ID (PK)
UNIT_NAME What value, if any is their in cascading PK's to FK's down thought the tables? Does this violate normalization?
