Either all operations within the transaction are completed successfully, or none of them are. This prevents a transaction from leaving the database in an inconsistent state. </p> <p>Consistency: A transaction must only bring the database from one consistent state to another. This means that the database must adhere to all defined rules and constraints before and after the transaction.</p> <p>Isolation: Multiple transactions can occur concurrently without interfering with each other. Each transaction operates as if it were the only one accessing the database, preventing conflicts and ensuring data integrity.</p> <p>Durability: Once a transaction is committed, its changes are permanent and will survive system failures or crashes. The database will recover the committed changes even if it needs to be restarted.</p> <ul> <li>By adhering to ACID principles, databases can ensure that: <ul> <li>Data remains accurate and reliable.</li> <li>Transactions are processed correctly and efficiently.</li> <li>The database system is resilient to failures and can recover gracefully.</li> </ul> </li> </ul> database beginners learning coding Adeyemi Racheal Wed, 20 Nov 2024 06:46:05 +0000 https://dev.to/raebuilds_/validator-libraries-in-nodejs-37po https://dev.to/raebuilds_/validator-libraries-in-nodejs-37po <ul> <li>Joi</li> <li>Yup</li> <li>Zod</li> <li>Class-Validator</li> <li>Validator</li> </ul> javascript beginners node typescript
