Final Answer:
The fundamental principles of transaction management within a database. Therefore, the correct answer is option b) Immediate; Indivisible
Step-by-step explanation:
The correct expansion for the "I" in the ACID properties of transactions is b) Immediate; Indivisible. According to the ACID properties (Atomicity, Consistency, Isolation, Durability), the "I" stands for "Isolation," emphasizing that transactions should be immediately applied and treated as indivisible units.
In the context of database transactions, the "Immediate" aspect underscores the necessity for transactions to take effect promptly without delays. Once a transaction is initiated, it should be promptly executed, ensuring that changes made by the transaction become immediately visible to other transactions or users interacting with the database.
The "Indivisible" aspect implies that a transaction should be treated as an indivisible unit, meaning that either all its operations are successfully completed, or none of them are. This ensures that the database remains in a consistent state, even in the presence of failures or interruptions during the transaction.
The principle of isolation helps maintain the consistency and integrity of the database by preventing interference between concurrent transactions. It ensures that the operations of one transaction are isolated from those of other transactions, preventing conflicts and preserving the accuracy of the database. In summary, the "Immediate; Indivisible" expansion highlights the importance of timely execution and the holistic treatment of transactions as cohesive, indivisible units to uphold the integrity of the database.
