What is the use of having SQL and DBMS and all those stuff which I don't understand?
Is it a must to have SQL in all finance apps?And this is a incident which happened to me ,
Once I went to book shop to purchase some stationary then I gave the stuff to the counter then the cashier started to bill.
Suddenly then I wanted to check to see if a book was available so I gave the book title and author. The cashier typed the words into the search box and then computer froze for a second.And the program quit stating some error I think. Then the technical guy came to scene and said that the database and the server got crashed and he said
Good thing we got a backup.But he said that the cashier is closed for now and you can get a handwritten bill for now.But Anyway they had to feed the data to the server anyway.
Is this how DBMS work or bad programming or bad design or What????Please Note I have no prior experience in programming related jobs so I might be incorrect. So please don't start scolding me.
