MIST 4610 Final Exam
Normalization - correct answer ✔Method for increasing the quality of
database design and a theoretical base for defining the properties or
relationships. Goal is identical to data modeling- a high fidelity system. The
recommended approach for arriving at a normal form is data modeling.
1NF - correct answer ✔If and only if all columns are single valued. All
occurrences of a row must have the same number of columns. An attribute
that can have multiple values must be represented as a one to many
relationship at a minimum.
2NF - correct answer ✔If and only if it is in first normal form, and all nonkey
columns are dependent on the key.
3NF - correct answer ✔If and only if it is in second normal form and has not
transitive dependencies. Boyce codd normal form is a stronger version of 3nf.
Functional Dependency - correct answer ✔A constraint between two
attributes in which the value of one attribute is determined by the value of
another attribute.
Full Functional Dependency - correct answer ✔A ____, is used to refer to
functional dependencies in which the entire collection of attributes in the
determinant is necessary for the relationship.
Transitive Dependency - correct answer ✔A condition in which an attribute is
dependent on another attribute that is not part of the primary key.

manipulate data (arrays, strings, etc.). Include domain, relations, relational
database, primary key, candidate key, alternate key, foreign key.
Integrity Rule - correct answer ✔Ensures that every row in every relation
must represent data about some specific object in the real world
Domain - correct answer ✔Set of values all of the same data type, ex the
domain of nation name is the set of all possible nation names. Domain
contains values that are in their atomic state; they cannot be decomposed
further.
Relation - correct answer ✔A table of n columns (attributes) and m rows.
Each column has a unique name and all of the values in a column are drawn
from the same domain.
Entity Integrity Rule - correct answer ✔A design constraint in a relational
database, requiring that the primary key have a non-null value. This ensures
that a specific object exists in the world and can be identified by reference to
its primary key value.
Referential Integrity - correct answer ✔A property of a relationship between
two tables. When Referential Integrity is on, the child table cannot contain a
foreign key value that does not have a corresponding value in the primary key
of the parent table.
