Teradata Interview Question:
What are two examples of an OLTP environment?
Submitted by: Administrator# Transactions take a matter of seconds or less.
# Many transactions involve a small amount of data.
Answer-1:
On Line Banking
On Line Reservation (Transportation like Rail, Air etc.)
Answer-2:
1- ATM
2- POS
Answer-3:
OLTP is typified by a small number of rows (or records) or a few of many possible tables being accessed in a matter of seconds or less. Very little I/O
processing is required to complete the transaction. For eg.
1. This type of transaction takes place when we take out money at an ATM. Once our card is validated, a debit transaction takes place against our current
balance to reflect the amount of cash withdrawn.
2. This type of transaction also takes place when we deposit money into a checking account and the balance gets updated.
We expect these transactions to be performed quickly. They must occur in real time.
