Which of the following is the original purpose of SQL?
A. To define the data structures
B. To specify the syntax and semantics of SQL data definition language
C. To specify the syntax and semantics of SQL manipulation language
D. All of the above.
Answer: Option C
Solution(By Examveda Team)
The original purpose of SQL (Structured Query Language) was to specify the syntax and semantics of SQL manipulation language. SQL was designed to interact with and manipulate data stored in relational database management systems. While SQL has evolved to include data definition language (DDL) for defining data structures and other functionalities, its primary purpose was to provide a standardized language for querying and manipulating data, making Option C the most accurate choice. Options A and B are not the primary original purposes of SQL, and Option D is not entirely accurate as it combines multiple purposes of SQL.Related Questions on Sql Miscellaneous
