What are the advantages of database management system over file management system?

A Database Management System (DBMS) is defined as the software system that allows users to define, create, maintain and control access to the database. DBMS makes it possible for end users to create, read, update and delete data in database. It is a layer between programs and data.

Compared to the File Based Data Management System, Database Management System has many advantages. Some of these advantages are given below −

Reducing Data Redundancy

The file based data management systems contained multiple files that were stored in many different locations in a system or even across multiple systems. Because of this, there were sometimes multiple copies of the same file which lead to data redundancy. 

This is prevented in a database as there is a single database and any change in it is reflected immediately. Because of this, there is no chance of encountering duplicate data.

Sharing of Data

In a database, the users of the database can share the data among themselves. There are various levels of authorisation to access the data, and consequently the data can only be shared based on the correct authorisation protocols being followed. 

Many remote users can also access the database simultaneously and share the data between themselves.

Data Integrity

Data integrity means that the data is accurate and consistent in the database. Data Integrity is very important as there are multiple databases in a DBMS. All of these databases contain data that is visible to multiple users. So it is necessary to ensure that the data is correct and consistent in all the databases and for all the users. 

Data Security

Data Security is vital concept in a database. Only authorised users should be allowed to access the database and their identity should be authenticated using a username and password. Unauthorised users should not be allowed to access the database under any circumstances as it violates the integrity constraints.

Privacy

The privacy rule in a database means only the authorized users can access a database according to its privacy constraints. There are levels of database access and a user can only view the data he is allowed to. For example - In social networking sites, access constraints are different for different accounts a user may want to access.

Backup and Recovery

Database Management System automatically takes care of backup and recovery. The users don't need to backup data periodically because this is taken care of by the DBMS. Moreover, it also restores the database after a crash or system failure to its previous condition. 

Data Consistency

Data consistency is ensured in a database because there is no data redundancy. All data appears consistently across the database and the data is same for all the users viewing the database. Moreover, any changes made to the database are immediately reflected to all the users and there is no data inconsistency.

As the volume of your data increases, so does the need for a database management system (DBMS), which is a computerized system that helps orchestrate large quantities of information.

A DBMS can improve your data processes and increase the business value of your organization’s data assets, freeing users across the organization from repetitive and time-consuming data processing tasks.

The result? A more productive workforce, better compliance with data regulations, and better decisions.

What is a Database Management System (DBMS)?

A database management system is a software tool used to create and manage one or more databases, offering an easy way to create a database, update tables, retrieve information, and enhance data. A DBMS is where data is accessed, modified and locked to prevent conflicts.

A database management system also provides tools to administer the database schema – which dictates the structure of the database itself. In many cases, the database management system will be seen only by the database developer, because the developer will provide a different front-end for the customer. This front-end could be considered, by the most technical definition, to be a database management system in its own right — however, it is more likely to go by another name, such as a customer relationship management (CRM) tool.

Business Benefits of a DBMS

Since quality data management implies a centralized view of data, teams need a solution that allows them to orchestrate everything, including monitoring who is accessing the system and where they’re accessing it from. A database management system helps improve organizational security, integration, compliance, and performance.

1. Improved data sharing and data security

Database management systems help users share data quickly, effectively, and securely across an organization. By providing quick solutions to database queries, a data management system enables faster access to more accurate data. End users, like salespeople, are able to speed up sales cycles and get more accurate in their sales prospecting.

2. Effective data integration

Implementing a database management system will promote a more integrated picture of your operations by easily illustrating how processes in one segment of the organization affect other segments. What once was done completely manually now can be fully automated and more accurate. The right DBMS will include flexible integration options to standardize data across multiple sources, remove duplicates, normalize, segment, and enrich data sets into custom workflows.

3. Consistent, reliable data

Data inconsistency occurs when different versions of matching data exist in different places in an organization. For example, one group has a client’s correct email, another the correct phone number. By using a proper database management system and data quality tools, you can be sure that an accurate view of data is shared throughout your organization.

4. Data that complies with privacy regulations

Database management systems provide a better framework for the enforcement of privacy and security policies. By orchestrating data in a unified manner, companies can manage privacy and data security centrally, helping unify their systems of record and lower the risk of regulatory violations.

5. Increased productivity

Deploying a DBMS typically results in increased productivity because a good DBMS empowers people to spend more time on high-value activities and strategic initiatives, and less time cleaning data and manually scrubbing lists.

6. Better decision-making

Decisions built on data are only as good as the information used. A database management system helps provide a framework to facilitate data quality initiatives. Better data management procedures generate higher-quality information, which leads to better decision-making across an organization.
