What is a transaction in the context of a database?
Correct Answer: A transaction is a sequence of operations that are executed as a single unit of work.
Step 1: Understand that a database is a place where data is stored.
Step 2: Know that a transaction is like a task that involves multiple actions.
Step 3: Think of a transaction as a recipe that needs to be followed completely.
Step 4: Realize that all the actions in a transaction must succeed or fail together.
Step 5: If one action fails, the whole transaction is canceled, just like if you forget an ingredient in a recipe.
Transaction Definition – A transaction is a sequence of operations that are executed as a single unit of work, ensuring data integrity.
ACID Properties – Transactions are often associated with ACID properties (Atomicity, Consistency, Isolation, Durability) which ensure reliable processing.
