1/8
Which of these examples correctly corresponds to a transaction (computing)?
answer A bilateral contract
answer Transfer of money between bank accounts
answer A debit card payment
right answer
Transfer of money between bank accounts.
2/8
What step is the most important to achieve a correct transaction??
answer Make sure there are no errors in terms of addition or subtraction.
answer Make sure you have sufficient resources.
answer Both are necessary.
right answer
Both are necessary. Transactions are either done completely or should not be done.
3/8
What does ACID mean?
answer None of the above is just the name of a program.
answer Atomicity, Consistency, Isolation and Durability .
answer Approval, Conclusion, Isolation and Duration.
right answer
Atomicity, Consistency, Isolation and Durability . Atomicity: ensures that an operation has been performed or not, and that it is complete.
Consistency: ensures that you only start what can be finished.
Isolation: ensures that one operation cannot affect others.
Durability: ensures that once the operation is performed, it will persist and cannot be undone in any way.
4/8
What is ACID for?
answer They guarantee that the transactions of a Database are processed reliably.
answer It is a protection mechanism from any external factor.
answer It is a way to organize the data, with different steps, so that it is not lost or a mistake is made.
right answer
They guarantee that the transactions of a Database are processed reliably.
5/8
How are the terms transaction and ACID connected?
answer ACID are recommendations for the protection of transactions.
answer ACIDs are tools to achieve a transaction.
answer ACID is the set of properties that ensure that transactions are processed reliably.
right answer
ACID is the set of properties that ensure that transactions are processed reliably.
6/8
Which example of the application of ACID in a transaction is correct?
answer Funds are transferred from one bank account to another, but there is an error, still no funds are subtracted or added to either account. Therefore, either the transaction is completed or the operation is denied.
answer A bank transaction is carried out, but there is an error in the system causing the transaction to fail and the amount to be canceled is discounted.
answer Both examples are correct.
right answer
Funds are transferred from one bank account to another, but there is an error, still no funds are subtracted or added to either account. Therefore, either the transaction is completed or the operation is denied.
7/8
Why does a database need an ACID?
answer A database that is guided by an ACID is the same as one that does not.
answer A database that implements ACID is less complex and easier to use.
answer A database that complies with every aspect of the ACID is considered reliable
right answer
A database that complies with every aspect of the ACID is considered reliable
8/8
What is a transactional database?
answer A transactional database is a database management system. Its objective is to ensure that transactions within the RDB are complied with or, failing that, are reversed.
answer A transactional database is for the recovery of lost transactions, that is, if any transaction had an error, it will be in charge of solving it in the easiest way possible.
answer It is a database used for the secure economic exchange of any kind. It makes the process easier and highly reliable.
right answer
A transactional database is a database management system. Its objective is to ensure that transactions within the BDR are complied with or, failing that, are reversed.
