ACID Transactions in a Database - What Is It All About?

Radek Białowas's article focuses on ACID transactions in the context of database systems. ACID is an acronym for four essential properties of transactions: Atomicity, Consistency, Isolation, and Durability. The author introduces readers to each of these concepts, emphasizing their importance in ensuring the reliability of operations in databases. Atomicity ensures that a transaction is treated as a single, indivisible operation, which protects against data corruption in case of errors. Consistency ensures that each transaction transforms the database from one valid state to another, upholding the rules of the system. Isolation ensures that concurrently executing operations do not interfere with each other except under specific conditions, while Durability means that once a transaction is committed, the changes are permanent, even in the event of a system failure. In the latter part of the article, the author discusses the practical applications of these properties and the challenges that may arise in implementing them.
