Terminology check: a program stored inside the database that performs a common action on data is called a(n) ________.

Introduction / Context:
Databases support server-side code for performance, security, and reuse. Two common programmable objects are triggers and stored procedures. They differ by how they are invoked.

Given Data / Assumptions:

• We want the generic program that can be invoked deliberately (for example, EXEC or CALL) to perform actions.
• The code resides in the database and can contain SQL and procedural logic.

Concept / Approach:
A stored procedure is a named program stored in the database, executed by clients or other procedures. A trigger is also stored but fires automatically in response to DML/DDL events; it is not invoked directly by users in normal operation.

Step-by-Step Solution:

Verification / Alternative check:
Examples: PostgreSQL functions, SQL Server stored procedures, Oracle procedures/packages.

Why Other Options Are Wrong:

• Trigger: event-driven code, not ad hoc invoked.
• Pseudofile: not a DBMS programmable object.
• None: incorrect because “stored procedure” fits.

Common Pitfalls:
Assuming triggers are interchangeable with procedures; triggers are tied to table/view events and execute implicitly.

Final Answer:
stored procedure
