Answer 1

Advantages of Database Management System (DBMS)

Better data sharing

The main advantage of DBMS is that it helps to create an environment in which the end users get better access to more and structured data. This structured and easy access makes it possible for end users to respond quickly to the change in their environment.

Better data security

Easy accessibility creates greater risks of data security breaches. Corporation invests a considerable amount of money, time, and effort to ensure the better security. A DBMS provides a framework for better implementation of data policies and data privacy.

Improved data integration

Wider access to well-structured data promotes combined a view of organisation’s operations and a richer view of the big picture. It becomes much easier to see the effects of one segment of the company on the other segment.

Minimized data inconsistency

Data inconsistency results due to the variable version of the same data in different places. For example, data inconsistency exists when a company’s sales department stores a sales representative’s name as “Tom Williams” and the company’s personnel department stores that same person’s name as “Thomas J. Williams” or when the company’s regional sales offices shows the cost of a product as $ 30.95 and its national sales office reflects the same product’s cost as $28.95. A DBMS helps is a reduction of data inconsistency due to the properly designed database.

Improved decision making

Improved and better-managed data makes it possible to generate better quality information which helps in better decision making. The quality of the information processed depends on the quality if the underlying data. A DBMS does not guarantee data quality but gives a framework to facilitate data quality initiatives.

Increased end-user productivity

Easy accessibility and availability of data, along with the tools that convert data into usable information, permits end users to make informed decisions. This brings the difference success and failure in the global economy.
