What term refers to the names of tables and columns that are called or manipulated?

• A. Constraints
• B. Identifiers
• C. Schemas
• D. Keys

Answer: (B)

In this context, the concept is identifiers. Identifiers are the names assigned to database objects like tables and columns so you can reference and manipulate them in SQL statements. When you write a query, the table name and column names you use are identifiers—you’re calling on those objects by their labels, such as employees and salary. They’re not about rules or structure themselves. Constraints are rules that enforce data integrity, schemas refer to the overall organization of the database, and keys are specific types of constraints used for uniqueness or relationships. So the names you use to refer to tables and columns are precisely identifiers.
