• The persons whose occupations need them to have access to a database for querying, updating, and producing reports are known as end users.
• Intelligent Users These are those users who communicate with the system through database query language rather than by creating programmes. They will work directly with the database; they are the SQL programmers. They create queries to update the database and delete, select, or insert data.
• The database is accessed by the knowledgeable end users, who then create their own applications to accomplish their own objectives. Business analysts, engineers, and scientists who are knowledgeable about the capabilities of the system are among them.
