Industries use RDBMS for various purposes.
Supports transactions
A transaction in an RDBMS is a simple set of operations that are done on the data in the database. These transactions are done completely only if all the conditions are met, if any condition is not satisfied the transaction would not be completed.
For example, I transfer 100 rupees to my friend, either my friend received all the 100 rupees or he receives none. In the same way, either 100 rupees is deducted from my account or there won't be any deduction. It is not like the 100 rupees is missed somewhere in between, either the money is in my friend's account or my account.
Supporting transactions in one of the biggest unique selling points(USPs) of a Relational Database Management System (RDBMS). This is also one of the reasons why RDBMS has fewer competitors.
Relationships
Industrial applications the majority of the time work with data that has relationships. since there is a need of managing this relational data, industries go for RDBMS.
Proper Schema
Schema is the blueprint of the database. In most industrial applications the schema almost remains unchanged over time.
In a banking application, in the KYC process, the same information would be collected by all the users and stored in the database.
Doing this the RDBMS Schema remains unchanged the majority of the time which makes data management easier and provides consistency in data storage.
Ensures Data integrity during read and write
RDBMS ensures data integrity during both read and write operations. Data integrity refers to the accuracy, consistency and reliability of data stored in a database.
