You need to identify all relations, their attributes, Primary Keys (PK) and Foreign Keys (FK) keys, entering them into the blank boxes according to the following example: Example: PROJECT(pno, dno) PK: (pno) FK: (dno) First, enter name of relation and the the attributes; then the value(s) for the PK and then values for the FK (if any). Relations fit on specific boxes. Look carefully how to place the relations in the boxes provided so all the responses could fit (attributes, PKs, FKs). NOTE: Use exactly the same spelling and letter case, otherwise it will be not recognized correctly by Carmen. R1 is [R1] ([a1],[a2],[a3]), PK:([pk1]), FK:([fk1]) R2 is [R2] ([b1],[b2]), PK:([pk2]) R3 is [R3] ([c1],[c2],[c3]), PK:([pkc1], [pkc2],[pkc3]), FK: ([fkc1]) R4 is [R4] ([d1]), PK:([pkd1]), R5 is [R5] ([e1],[e2]), PK:([pke1], [pke2]), FKs: ([fke1],[fke2])
