Q1Domain Verified
In the context of "The Complete SQL & Relational Database Design Course 2026," which of the following relational database design principles, when violated, is most likely to lead to update anomalies where a single piece of information needs to be updated in multiple rows, increasing the risk of inconsistency?
First Normal Form (1NF)
Denormalization for performance
Referential integrity
Third Normal Form (3NF)
Q2Domain Verified
Considering the advanced SQL concepts covered in "The Complete SQL & Relational Database Design Course 2026," what is the primary advantage of using window functions over traditional aggregate functions for tasks like calculating running totals or rankings within partitions?
Window functions allow calculations across rows related to the current row without collapsing rows.
Window functions are syntactically simpler for all complex analytical queries.
Window functions inherently enforce data integrity constraints.
Window functions are always more performant than subqueries.
Q3Domain Verified
In the context of database indexing as presented in "The Complete SQL & Relational Database Design Course 2026," what is the fundamental trade-off when choosing between a B-tree index and a hash index for a specific query scenario?
Hash indexes are always preferred for primary key lookups due to their O(1) complexity.
B-tree indexes are faster for range queries, while hash indexes are faster for exact matches.
B-tree indexes support ordering and sorting of results, while hash indexes do not.
Hash indexes are generally more space-efficient than B-tree indexes.
