Understanding Data Storage in Relational Databases

In the world of databases, data is organized and presented in a structure that resembles tables with rows and columns. This arrangement simplifies how we work with data and helps us make sense of information.

The Relational Database and ACID Principles

Relational databases are well-known for adhering to the ACID principles, which ensure data integrity and reliability in transactions. Here's a brief overview:

• Atomicity: It ensures that database transactions are treated as a single unit, so they either fully succeed or fully fail, with no partial changes.

• Consistency: After a transaction, the database must remain in a consistent state. In other words, it moves from one valid state to another.

• Isolation: Transactions should be isolated from each other to prevent interference. Each transaction should execute independently.

• Durability: Once a transaction is committed, its changes are permanent and will survive any system crashes.
