In the event that referential integrity of a database were to be compromised, what would be the resulting consequences? What are the most frequently occurring errors that one tends to commit?
Database normalization is a very important process in designing and organizing tables (relations) and their columns (attributes or fields) in a relational database. Therefore, what are the consequences (problems) if a database was designed without it? Would the database still work?
What are the benefits of using a transaction to group database operations together that need to either all complete or be rolled back so none of them complete? Here is an example of when a transaction should definitely be used to be helpful: When any bank / financial institution processes a transfer of money from one account to another account, the operations involved are always (1) to subtract a given amount of money from the source account and (2) add that same amount of money to the destination account. They have to be sure the software doing the transfer groups the above 2 required database operations in a transaction to ensure that if there is any system error/problem during these operations there is no way that money could be accidentally subtracted from an account but not added to the account it is supposed to be transferring to or customers will be very upset at the loss of money!
