What is meant by Transactions?
The term "transactions" refers to a sequence of operations that are executed as a single, indivisible unit. A transaction must be either fully completed or fully reversed (this principle is known as the "ACID" property: Atomicity, Consistency, Isolation, Durability). Transactions are especially important in database systems and enterprise software to ensure data integrity and consistency.
