A software that caters to your need for storing and organizing data and records is a database management system(DBMS). You will frequently see DBMS instead of the full name of a database management system because it is the accepted abbreviation. A database system makes it simple to access data. It can access data using a variety of queries and different categories of data can be stored individually. Now if you are an amateur in the field, you may have questions about the purpose of database system or what are the main functions of a database system. Don’t worry we will guide you through them all!
1. What is Database and its Benefits?
Before understanding the purpose of database system, let’s explain the meaning of a database. A database is a group of data that has been arranged to make it simple to manage, collect, process and update data. A database could, for instance, be as straightforward as a list of customers’ names arranged alphabetically. Or it might be a list of the numbers in ascending order. A database management system has been named the software that houses databases (DBMS). It was created specifically to handle, protect, and save data in a database and provides advantages like increasing employee productivity and data exchange providing more security, privacy, and minimal data inconsistency.

2. What are the Features of Database?
Giving consumers an abstract view of data, or hiding some of the specifics of how data is maintained and kept, is a key element of database systems.
- Data Abstraction: Data abstraction is the ability to hide certain details from users and only display those that are absolutely necessary. Since many database system users lack computer literacy, developers use multiple levels of abstraction to obscure the complexity of users and streamline user interactions with the system.
- Instances and Schemas: As data is added to and removed from databases, they evolve over time. The term instance of the database refers to the group of data that is kept there at a specific time.
- Data Backup: It provides your data with a backup which helps in reducing the chance of losing your files and information.
3. What are 10 Advantages of Database?
- Improves employee productivity and data sharing
- Gives zero redundant data
- Gives data greater security and privacy.
- Demonstrates the larger picture
- Increases your capacity to generate more revenue
- Ensures data consistency
- Reliable backup and restoration
- Enhances your marketing efforts overall and guarantees better customer service
- Standardization is possible
- Disputed requirements can be resolved
4. What is the Main Purpose of Database?
Now that you are aware of the advantages, let us understand the main purpose of database system. A database is a collection of data that is organized so that it can be quickly accessed, controlled, and updated. One of its primary functions is to accurately and efficiently store and retrieve information. It aims to offer a way to manage all the data it contains.

- Hardware: The term hardware refers to the actual physical components of a computer, which includes a variety of storage devices, such as hard drives, and input and output devices, such as monitors and printers.
- Software: The software makes up the majority of a database management system. Software is a group of programs or a set of programs that provide instructions to a machine and is a complete collection of scripts, instructions, and processes used to run a computer system.
- Data: The collection of information kept in the database is referred to as data. Structured, non-structural, and logical data are all types of data that are kept in databases. Database dictionaries are used to document, centralize, and control how the data is used in an organization.
- Procedures: Procedures are broad guidelines for utilizing a database management system. This comprises steps for installing a DBMS, logging in and out of DBMS software, managing databases, and creating backups, and reports, among other things. Access control, data validation, and reducing network traffic between clients and DBMS servers are all possible with procedures.
- Database Access Language: It is a technical language that is used to write commands to access, update and delete the data which is stored in the database. Users can make use of this to create new tables and databases, and insert and delete any data.
6. What is Purpose of Database System?
You are now aware of the components, so it’s about time that we learn the purpose of database system as well. The primary purpose of a database is to store, retrieve and run the required queries on any data. It caters to large bodies of information and aims to provide a mechanism to administer any database it contains. (See What is System Unit in Computer?)
7. What are the Main Functions of a Database System?
The major functions of a database system revolve around:
- Collecting and organizing the data
- Segregating the given data into tables, columns, and rows
- Security Management
- Data Dictionary Management
- Keeping a backup and ensuring the recovery of data.
8. What are the Major Benefits of Database System?
- Increases Productivity and Data Sharing: Users can more easily access a variety of information in one place when the data is kept in a database through a database management system. People are able to respond swiftly and form wiser decisions as a result. Marketers will have more access to consumer data, for instance, enabling them to better understand consumers and react rapidly to changes in their needs or market preferences.
- Nothing Redundant: One of the main advantages of databases is the reduction of data redundancy. Data duplication and elimination are prevented by a database management system (DBMS), which reduces storage requirements and speeds up access.

After gaining an insight into the purpose of database system, one might also ponder over the importance of database management systems. This system enables more recent and improved updates and provides easy access to any sort of data or information. For instance, brand managers can update the present information, delete information that is no longer needed, and add new information using a beneficial and effective database management system.
