Difference between Relational Database & Blockchain?

In this digital world, everyone is curious about data. All of the digital devices gather our data from the moment we get out of bed till the moment we go to sleep. Relational databases and blockchain both function as useful technologies for information collection. Do you ever consider the distinction between a relational database and a blockchain?

Relational database is a centralized ledger that systematically contains information in a table. Blockchain is a decentralized distributed ledger that holds information in units called blocks.

Let’s Discuss the difference between them.✍️

• In Relational database anyone can enter the data. But in blockchain to complete a transaction, peers must ratify it.
• We can do operations like Create, Read, Update, and Delete (CRUD) in the database. But in blockchain, we can only Insert & View data. We Can’t delete or Edit it. (Every user has a copy of every transaction, so Deleting is impossible)
• When we override names in the database, the old name will disappear. But in blockchain, it behaves as two users. (You can see both the characters in the blockchain).
• On the blockchain, anyone can verify, unlike in databases where only administrators can.
• The cost of implementing and maintaining a blockchain is relatively high compared to databases.

I hope you fully understand the distinctions between blockchain and relational databases and when each should be used.✨. Let’s talk about another informative topic soon.
