6. Determining optionality and cardinality
Each instance of Table B is related to a maximum of one and a minimum of one instance of Table A
TABLE A
TABLE B

7. Each instance of Table A is related to zero, one or more instances of Table B
TABLE B

9. Different notations are used to represent the cardinality of relationships
1:1
1:M
M:N
Which one was shown with more detail in the previous examples?

11. ERD Associative Entity

12. Bridge Tables
A Company is owned by several Owners who own stock. But Owners can have stock in many companies. Thus COMPANY and OWNER are related as Many to Many.

13. Bridge Tables
Let’s say that Joe Small owns $5000 of NORTEL and $3000 of ROGERS.
Bill owns $10000 NORTEL and $7000 of Gillette and $5000 of Big “O”
Mary has $50000 of NORTEL.
The Ownership table (bridge table) has an entry for each.
Relations required for the M:N relationship between COMPANIES and OWNERs
I COMPANY(Co#, CoName)
II OWNERSHIP( Co#, OwnerId , DollarAmount) This bridge table has
III OWNER( OwnerID, OwnerName ) more than just the PK!!!

14. LAB’s based on PREMIERE
Labs 8 and 9 Normalization exercises were based on the PREMIERE collection tables
ORDERS
ORDERLINE
PART
ORDERLINE was a bridge entity between ORDERS and PART

18. Bridge Tables
The Orderline table (bridge table) has unique entries with a concatenated key that match up with one and only one order in the ORDERS table or one and only one part in the PART table
What is missing in the Orderline table?
Relations required for the M:N relationship between ORDERS and PART
I ORDERS(Order#, OrderDate, Cust#)
II ORDERLINE( Order#, Part#, QtyOr, QuotedPrice)
III PART( Part#, PartDesc, OnHand, Class, Warehouse, ListPrice)

19. What is Normalization?
Normalization is a series of steps used to evaluate and modify table structures to ensure that every non-key column in every table is directly dependent on the primary key.
The results of normalization are reduced redundancies, fewer anomalies and improved efficiencies.

20. First Normal Form (1NF) 1 2 3

21. Second Normal Form (2NF)1 2

22. Third Normal Form (3NF) 1 2

23. Normalization Abstract Example
For the following un-normalized relation:
RELN1[A, B, {C, D}, E, F, G]
where E can be determined by knowing only A, G can be determined by knowing only F and C can be used to determine D
1NF: (without splitting the table)
RELN1[A, B, C, D, E, F, G]
2NF:
RELN1[A, B, F, G]
RELN3[A, E]
RELN2[A, B, C, D]
3NF:
RELN1[A, B, F]
RELN4[F, G]

24. Nested Repeating Groups Example
Representation of a user view in UNF may result in nested repeating groups.
The process of resolving a repeating group must be performed starting with the outermost repeating group first to produce a temporary new relation containing a repeating group.
The process of resolving a repeating group must then also be performed on this temporary relation
