What is the MongoDB Query Language (MQL)?

The MongoDB Query Language (MQL) is specifically designed to enable users to query and manipulate data stored within a MongoDB database. Its syntax allows for the construction of complex queries that can filter, sort, and update data, making it an essential tool for developers working with MongoDB.

MQL supports a variety of operations such as finding documents, aggregating data, and modifying records, all tailored to work seamlessly with the NoSQL structure of MongoDB. The language's capability to handle JSON-like documents allows for flexibility and efficiency when interacting with large datasets.

In contrast, the other options do not accurately describe MQL. The first choice discusses a syntax used for web development, which pertains more to HTML, CSS, or JavaScript than to MQL. The second option refers to data visualization, which involves interpreting and presenting data visually rather than querying and manipulating it. Lastly, managing user accounts is a function typically handled by authentication and authorization systems, not by a query language like MQL. Therefore, the correct answer reflects MQL's primary role in data manipulation within MongoDB.
