Fill in the blank: When using a relational database, data analysts write _____ to request data from the related tables.

In relational databases, you request data from related tables by writing queries. A query specifies what data you want and how to combine information from multiple tables that relate to each other. Analysts usually use a SELECT statement to pull specific columns and join linked tables on matching keys, such as a customer_id that appears in both a customers table and an orders table. This allows you to retrieve cohesive results that reflect relationships across the data. Other terms don’t fit as precisely. Procedures are stored routines that perform tasks and may return results, but they’re not the typical way to ad hoc request data. Commands and requests aren’t the standard terminology for the data retrieval process in relational databases.
