Improves the likelihood of success through pre-vetting. Strengths * Can offer anonymity while retaining high levels of personal detail and control over how these are shared (I. E. Citizen held records). * May include advanced testing to determine compatibility or matches between participants and records. Useful research tool, e. G. For determining average prices. Weaknesses * There is often a charge to access the database. * Sometimes there can be a stigma associated with being on a private database (e. G. If participants are looking to date). * Can soon become out of date and usefulness out of perspective it inactive records are not deleted. End users are those persons who interact with the application directly. They are responsible to Insert, delete and update data in the database. They get Information from the system as and when required.
Types: a) Direct users: Direct users are the users who SE the computer, database system directly, by following instructions provided in the user interface.

There are several categories of end users: 1 . Casual end users occasionally access the database, but they may need different information each time. They use a sophisticated database query language to specify their requests and are typically middle- or high-level managers or other occasional browsers. 2. Naive or parametric end users make up a sizable portion of database end users.

The tasks that such users perform are varied: Bank tellers check account balances and post withdrawals and deposits. Reservation clerks fur airlines, hotels, and car rental companies check availability for a given request and make reservations. Clerks at receiving stations for courier mail enter package identifications via bar codes and descriptive information through buttons to update a central database of received and in-transit packages. 3.
Sophisticated end users include engineers, scientists, business analysts, and others who thoroughly familiarize themselves with the facilities of the DB’S so as to implement their applications to meet their complex requirements. 4. Stand-alone users maintain personal databases by using ready-made program packages that provide easy-to-use menu-based or graphics-based interfaces. An example is the user of a tax package that stores a variety of personal financial data for tax purposes.
