Question:
Suppose you had an entity with the following attributes (see posted data dictionary):
INV_NUMBER, LINE_NUMBER, INV_DATE, CUS_CODE, P_CODE, P_PRICE, P_DESCRIPTION, LINE_UNITS, LINE_PRICE, V_CODE, V_NAME
where (INV_NUMBER, LINE_NUMBER) is a composite primary key.
Answer the following questions:
- Identify all partial dependencies.
- Identify all transitive dependencies.
Make sure to justify your answers, e.g. if A -> B is a partial dependency (where A and B are two of the attributes) you need to explain why it is a partial dependency.
