SQL allows users to perform a variety of operations on the data, such as querying, updating, inserting, and deleting records within the database. This language is used universally across many database systems, enabling high-performance and reliable data management for corporate environments where data integrity and complex queries are critical.

In contrast, NoSQL represents a broad category of database systems that do not use SQL as their primary interface. While NoSQL databases are often used for large-scale data storage and can handle unstructured data types, they are not specifically tailored for traditional corporate database scenarios like relational databases.

Query by Example (QBE) is a query language that uses a graphical interface, which is less common in professional database management compared to SQL. While it can be useful for certain types of database interaction, it does not provide the full range of functionalities and structured capabilities that SQL offers.

Hypertext Markup Language (HTML) is primarily a markup language used for creating and structuring content on the web, not for database management. It does not provide any functions for querying or manipulating data within a database.
