Part $1)$

Identify $4$ database constraints $($examples can include: Not NULL, primary key, unique, domain; there can be different ones as well$)$ and data integrity, security, and availability issues related to relational databases.

Part $2)$

HINT: Review the Normalization Process: Parts and Suppliers One$-$to$-$Many Example in the Terms and Concepts discussion.

Background

We want to keep track of the price we charge for each type of part, the supplier for each type of part, and the amount we pay the supplier for each type of part $($the cost$).$ Each supplier can provide us with many different types of parts, but each part can be provided to us by only one supplier. This requires a one$-$to$-$many relationship.

Functional analysis:

Part $---->$ Price, Cost, Supplier, Street, City, State, Zip, Telephone

Supplier $---->$ Street, City, State, Zip, Telephone

Part $---->$ Price, Cost, Supplier

Table:

Parts $($Part$,$ Price, Cost, Supplier, Street, City, State, Zip, Telephone$)$

Compete the following:

$1.$ Include a definition of $2$ normal form

$2.$ Is the above table in $2$NF$?$

$3.$ Using the table and field names in the above table explain your answer.
