A query language primarily facilitates interaction with a database, allowing users to retrieve, search for, and update data stored within that database. Its core functions revolve around performing operations such as retrieving records, inserting new data, modifying existing data, and deleting records. This interface is crucial for database management, as it enables users to efficiently manipulate and manage the information stored.

In contrast, managing server performance pertains to optimizing the resources and efficiency of a server running a database, which is not the function of a query language. Creating user interfaces involves designing visual components that allow users to interact with software applications, whereas a query language operates beneath the interface to manage data. Processing data encryption relates to securing data through encryption methods, which is a separate concern from interacting with databases via a query language. Thus, the primary emphasis of a query language lies in its ability to perform queries and updates on a database.
