What do databases produce based on queries from users?

Databases primarily produce reports based on user queries because reports are formatted outputs that summarize and organize data in a way that is useful for decision-making and analysis. When users query a database, they are often looking to extract specific data points or a collection of related data that provides insights or information.

Reports can be tailored to include various types of data representations such as tables, lists, and specific sections of detailed information that allow users to draw conclusions or understand trends. This makes reports a common and crucial output of database systems, as they facilitate communication of the underlying data.

While documents, graphs, and charts can be generated from database queries, they are generally considered additional forms of representation rather than the primary product of direct database query output. Charts and graphs are often used within reports to visualize the data, but the foundational output that summarizes the queried data is the report itself.
