Which language is specifically related to database servers?

The correct answer is SQL, which stands for Structured Query Language. SQL is a standard programming language specifically designed for managing and manipulating relational databases. It allows users to perform various operations such as querying data, inserting new records, updating existing data, and deleting records from a database. SQL is fundamental for anyone working with database servers, as it provides the necessary commands to interact directly with the database system, making it integral to database management and operations.

While Python, Java, and PHP are versatile programming languages used for various applications including web development and software engineering, they are not specifically designed for database interaction in the same way SQL is. Each of these languages can work with databases, often using SQL queries as part of their functionality, but they do not replace SQL's role as the standard language for database commands and operations.
