Question at position 9 A business transaction requires:a trigger.several actions against the database.human intervention.a stored procedure.

BlackTom AI · Accepted Answer

When assessing what a business transaction requires in the context of a database system, we examine the role of different components and activities involved.
Option 1: 'a trigger.' A trigger is an event-driven procedure that runs automatically in response to certain database events, but a business transaction does not inherently require a trigger to occur; it's a mechanism that may or may not be used within a transaction.
Option 2: 'several actions against the database.' This choice captures the essence of a transaction, which typically comprises a sequence of operations (reads, writes, updates, deletes) that together constitute a unit of work affecting the database. The core idea is atomicity: either all actions succeed, or none do, implying multiple actions are usually involved.
Option 3: 'human intervention.' By definition, a business transaction is designed to be executed with minimal human intervention, ensuring consistency and reliability; requiring human input would undermine the automated, atomic nature of transactions.
Option 4: 'a stored procedure.' While a stored procedure can encapsulate a set of database actions that run as part of a transaction, it is not a universal requirement for a transaction to exist. Transactions can be implemented in various ways, with or without stored procedures.
In summary, the central characteristic of a database transaction is that it encompasses a set of actions against the database that are treated as a single unit of work, ensuring atomicity and consistency.
