1. Data sharing

The data stored in a database can be share. 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. The data in a database is available to all managers and end users. 

2. Data security

Easy accessibility creates greater risks of data security. Since the data in a database can be accessed by all the end users and the managers, there occur some security problems. But DBMS overcome this problem by giving different authority to all users. 

3. Reduce data redundancy

The same data may be duplicated at many times in many places, which is called data redundancy. A DBMS reduces the duplicated data from a database.

4. Minimized data inconsistency

When the same data is duplicated and changed are made at one site, and not on other sites, it causes data inconsistency. But DBMS reduces the inconsistency problem by elimination two entries regarding the same data. 

5. Data integrity

Integrity means that the data stored in a database is correct or accurate. So, the problem of integrity is the problem of ensuring that the data in the database is correct. In a database the same data may be duplicated at many times or places, due to the data redundancy, there arises the problem of inconsistency. But DBMS avoids the data inconsistency problem, so it improves the data integrity.

5. 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.

6. 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.
