Q1Domain Verified
In the context of relational database design as taught in "The Complete Relational Database Design Course 2026", what is the primary implication of achieving Third Normal Form (3NF) for a table?
It guarantees that every non-key attribute is functionally dependent on the primary key, and no transitive dependencies exist.
It ensures that all non-key attributes are fully dependent on the primary key, and there are no transitive dependencies.
It requires that all non-key attributes are functionally dependent on the entire primary key, thus removing transitive dependencies.
It mandates that all non-key attributes are dependent only on the primary key, thereby eliminating transitive dependencies and partial dependencies.
Q2Domain Verified
During the normalization process, a student encounters a situation where a table contains redundant data that can be split into two tables, maintaining referential integrity. According to "The Complete Relational Database Design Course 2026", this scenario typically indicates the table is in which normal form, requiring further decomposition?
First Normal Form (1NF)
Boyce-Codd Normal Form (BCNF)
Third Normal Form (3NF)
Second Normal Form (2NF)
Q3Domain Verified
"The Complete Relational Database Design Course 2026" emphasizes the importance of choosing appropriate data types. If a column is intended to store unique identifiers for products that will never be negative and will always be integers, which data type would be the most efficient and appropriate choice, considering both storage and performance?
DECIMAL(10,0)
FLOAT
INT UNSIGNED
VARCHAR(20)
