Saira owns a small business and she frequently makes transactions. Sometimes she makes
payments and other times payments are credited in her account. One of her customer Tania purchased
a product and credited payment while another payment by Saira was in progress. Now the sequence of
transaction is as follows:
1. Tania’s account read amount in saira’s account
2. Saira’s account read amount in saira’s account
3. Tania added Rs. 500/- in original amount (that was lets suppose Rs. 60,000/
4. Saira’s account subtracted Rs. 2000/- that she debited in someone else’s account form the
original amount (that was Rs. 60,000)
5. Tania’s account committed the transaction
6. Saira’s account committed the transaction
Draw the above-mentioned sequence in form of a table and see if there is a problem. What this
problem is called and how can we avoid such kind of problem? Propose some solutions (at least two)
and then explain which one is better and why?
