Database is a collection of data which is interrelated and is used to retrieve, insert, and modify data efficiently. It can also be used to organize the data in the database in a schema, table, views, reports, etc.
Information retrieval, modification, deletion and insertion can be done using the database.
Database Management System
Database management system offers an interface for performing a number of operations like creation of a database, data storage, updating data, creating tables to store information in it and much more. DBMS also offers security and protection to the database and maintains data consistency in case there is more than one user.
DBMS enables users for the tasks as stated below:
- Data definition: DBMS is used for the creation of definition, their modification, and the removal of definitions that define the organization of data in the database.
- Data updation: DBMS is used for updating the data in the database through the means of modification, insertion, and deletion of actual data.
- Data retrieval: It is used for the retrieval of data by the application to perform various functions.
- User Administration: DBMS is used for registration and monitoring of users, concurrency control, maintaining data integrity, monitoring performance, enforcing data security, and recovering data lost due to critical failure.
Characteristics of DBMS
- It establishes a digital repository on a server to store and manage the data in the database.
- It provides a clear view and a logical view of the process manipulating the data.
- DBMS offers automatic backup and recovery of the data.
- DBMS maintains data in a healthy manner in case of failure due to ACID properties.
- It has the ability to reduce the complicated relationship between the data in the database.
- It is used for processing and manipulation of the data.
- It provides security of data.
- It can view the database from different viewpoints depending on the needs of the users.
Advantages of DBMS
- Controls database redundancy: All the data is stored in one place, and that recorded in the database and hence controls the redundancy in the database.
- Data sharing: DBMS allows users with authority to share the data in the database with multiple users.
- Easy Maintenance: The centralized nature of the database helps in the easy maintenance of the data.
- Reduce time: It reduces the maintenance need and development time.
- Backup: It automatically backs up data to maintain its integrity in case of failure.
- Multiple user interfaces: It offers a number of user interface to multiple users.
Disadvantages of DBMS
- Cost of software and hardware: It requires a number of high powered processors and large size memory to run DBMS.
- Size: a Large amount of storage size is required to run DBMS efficiently.
- Complexity: DBMS adds an additional layer of complexity to the data.
- Higher impact of failure: DBMS faces a higher risk of losing the data since all the data is stored at a single location and a catastrophic failure can wipe it all.
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.

Database Management System (DBMS) is basically a collection of interrelated data and a set of software tools/programs which access, process, and manipulate data. It allows access, retrieval, and use of that data by considering appropriate security measures. The Database Management system (DBMS) is really useful for better data integration and security. Advantages of Database Management System (DBMS): Some of them are given as follows below.
