database users

Users of Database management system:-

1. Database administrators: responsible for authorizing access to the database, for coordinating and monitoring its use, acquiring software, and hardware resources, controlling its use and monitoring efficiency of operations.


2. Database Designers: Responsible to define the content, the structure, the constraints, and functions or transactions against the database. They must communicate with the end-users and understand their needs.


3. End users : End users are the people whose jobs require access to the database for querying, updating, and generating reports; the database primarily exists for their use. There are several categories of end users:

Casual  End User: access database occasionally when needed. But they may need different information each time.

Naïve or Parametric End user : they make up a large section of the end-user population. They use previously well-defined functions in the form of canned transactions” against the database. Examples are bank-tellers or reservation clerks who do this activity for an entire shift of operations.
                                                           
Sophisticated End User : These include business analysts, scientists, engineers, others thoroughly familiar with the system capabilities. Many use tools in the form of software packages that work closely with the stored database.

Stand-alone End User : Mostly maintain personal databases using ready-to-use packaged applications. An example is a tax program user that creates his or her own internal database.
