Which concept allows you to combine data from two relational tables for additional insights?

• A. Inner Join
• B. Joins
• C. Full joins
• D. Cross Joins

Answer: (B)

Joins let you combine data from two relational tables to gain additional insights. By linking rows on a related column (a key), you can pull together related information from both tables in a single result set, such as matching customers with their orders to analyze purchasing patterns. This broad capability is captured by the concept of joins, which encompasses all ways of relating tables. Specific variants—like inner join, full join, and cross join—define how rows are matched and what results are returned, but the general mechanism enabling combining data across tables is the join.
