How Database Views Restrict Access to Data

Any database is, first and foremost, a large body of information, not all sections of which can be read by humans. Typically, databases have access levels, which determine whether a specific individual (basically a specific device) is allowed to access certain sections of the database. Views in SQL are database objects that are always created based on one or more underlying tables, so they are often called virtual tables (Sławińska, 2020). In general, it is correct to say that this information is the whole set of data that is stored in the database. Views at the same time are part of the information that the user sees, which means that the use of such systems allows you to hide the complex and overloaded details of virtual tables that are not essential for display. The user cannot retrieve data to those Views categories to which he does not have appropriate access because SQL hides this information from the user. Yes, a stored procedure can guarantee no less control over the data because users usually do not have access to procedures, which means that SQL-created instructions limit the availability of the data presented to the user. Thus, data is input or output but does not change procedures, which means that stored procedures should be considered a solid built-in tool for data control.
