i.
Improved data sharing: The
DBMS helps create an environment in which end users have better access to more
and better-managed data. Such access makes it possible for end users to respond
quickly to changes in their environment. In DBMS, data can be shared by
authorized users of the organization. The DBA manages the data and gives rights
to users to access the data. Many users can be authorized to access the same
set of information simultaneously. The remote users can also share same data.
Similarly, the data of same database can be shared between different
application programs.

Improved data security: Data security
is the protection of the database from unauthorized users. Only the authorized
persons are allowed to access the database. Some of the users may be allowed to
access only a part of database i.e., the data that is related to them or
related to their department. Mostly, the DBA or head of a department can access
all the data in the database. Some users may be permitted only to retrieve
data, whereas others are allowed to retrieve as well as to update data. The
more users access the data, the greater the risks of data security breaches.
Corporations invest considerable amounts of time, effort, and money to ensure
that corporate data are used properly. A DBMS provides a framework for better
enforcement of data privacy and security policies.

iii.
Data integration: In
DBMS, data in database is stored in tables. A single database contains multiple
tables and relationships can be created between tables (or associated data
entities). This makes easy to retrieve and update data. Wider access to
well-managed data promotes an integrated view of the organization’s operations
and a clearer view of the big picture. It becomes much easier to see how
actions in one segment of the company affect other segments.

iv.
Minimized data inconsistency: By
controlling the data redundancy, the data consistency is obtained. If a data
item appears only once, any update to its value has to be performed only once
and the updated value (new value of item) is immediately available to all
users. Data inconsistency exists when different versions of the same data
appear in different places.

Improved data access: The
DBMS makes it possible to produce quick answers to ad hoc queries. From a
database perspective, a query is a specific request issued to the DBMS for data
manipulation—for example, to read or update the data. Simply put, a query is a
question, and an ad hoc query is a spur-of-the-moment question. The DBMS sends
back an answer (called the query result set) to the application.

Improved decision making: Better-managed
data and improved data access make it possible to generate better-quality
information, on which better decisions are based. The quality of the
information generated depends on the quality of the underlying data. Data
quality is a comprehensive approach to promoting the accuracy, validity, and
timeliness of the data. While the DBMS does not guarantee data quality, it
provides a framework to facilitate data quality initiatives.

Increased end-user productivity: The
availability of data, combined with the tools that transform data into usable
information, empowers end users to make quick, informed decisions that can make
the difference between success and failure in the global economy.
