End users are the people whose jobs require access to the database for querying, updating, and generating reports;

There are several categories of end users:

• Casual end users occasionally access the database, but they may need different information each time. They use a sophisticated database query interface
• Naive or parametric end users make up a sizable portion of database end users. Their main job function revolves around constantly querying and updating the database, using standard types of queries and updates
• Sophisticated end users include engineers, scientists, business analysts, and others who thoroughly familiarize themselves with the facilities of the DBMS in order to implement their own applications to meet their complex requirements.
• Standalone users maintain personal databases by using ready-made pro-gram packages that provide easy-to-use menu-based or graphics-based interfaces. An example is the user of a financial software package that stores a variety of personal financial data.
