What operations are carried out on data via database queries?

The correct choice, which focuses on the operations carried out on data via database queries, emphasizes the fundamental actions that can be performed within a database management system. When utilizing database queries, the primary operations are to retrieve existing data, modify it when necessary, and delete records that are no longer needed or relevant.

Retrieving data allows users to access specific information from the database based on set criteria, which is essential for decision-making and data analysis. Modifying data is crucial for maintaining accuracy and relevance, enabling users to update information as circumstances change. Finally, deleting records can be vital for data management, ensuring that outdated or incorrect data does not clutter the database.

While other choices may involve actions related to data, they do not specifically correspond to the core operations carried out using standard database queries. For example, analyzing and visualizing data are important but pertain more to data processing and presentation rather than direct query operations. Thus, the emphasis on retrieval, modification, and deletion reflects the fundamental capabilities of database queries.
