Answer
Correct Answer: Structured Query Language
Explanation
Introduction / Context:SQL is the standard language used to define, manipulate, and control relational data. Knowing the correct expansion of the acronym is foundational.
Given Data / Assumptions:
- SQL originated at IBM (as SEQUEL) and evolved under ANSI/ISO standards.
- Used for DDL, DML, and DCL/TCL statements.
Concept / Approach:Despite historical naming (SEQUEL), the formal expanded name is “Structured Query Language.” It reflects the declarative nature and structured schema of relational databases.
Step-by-Step Solution:
Identify correct expansion → Structured Query Language.Eliminate distractors that misuse “Sequential” or “Question.”Verification / Alternative check:Any DBMS documentation (Oracle, SQL Server, PostgreSQL) references SQL as Structured Query Language.
Why Other Options Are Wrong:They are nonstandard expansions and do not reflect the accepted industry terminology.
Common Pitfalls:Confusing the historical “SEQUEL” acronym with the modern “SQL.”
Final Answer:Structured Query Language
