Answer to Question 1

Accidental misuse refers to data updates (insert, delete, modify) that are the result of an accident rather than a deliberate malicious attempt. Malicious data updates are the result of unauthorized malicious misuse of a database system.

Answer to Question 2

Binary search is a nonlinear search method that takes advantage of sorted lists. It divides the sorted list initially in two parts (hence the name binary) of the same size by looking up the value in the middle of the list. If the searched-for value is larger than the value in the middle of the list, the top part of the list is eliminated from the search space. Equivalently, if the searched-for value is smaller than the value in the middle of the list, the bottom part of the list is eliminated from the search space. Either way, the search space is reduced by half in one single step. This process of looking up the value in the middle and halving the search space is repeated in the remaining part of the list, until the searched-for value is found.
