QUES: This may be managed directly on an individual basis, or by the assignment of individuals and privileges to groups, or (in the most elaborate models) through the assignment of individuals and groups to roles which are then granted entitlements. Data security prevents unauthorized users from viewing or updating the database. Using passwords, users are allowed access to the entire database or subsets of it called "subschemas". For example, an employee database can contain all the data about an individual employee, but one group of users may be authorized to view only payroll data, while others are allowed access to only work history and medical data. If the DBMS provides a way to interactively enter and update the database, as well as interrogate it, this capability allows for managing personal databases.

What is possible when a DBMS corrupts a database?
What is the answer?
ANS: unanswerable
QUES: On Sentinel Peak (also known as "'A' Mountain"), just west of downtown, there is a giant "A" in honor of the University of Arizona. Starting in about 1916, a yearly tradition developed for freshmen to whitewash the "A", which was visible for miles. However, at the beginning of the Iraq War, anti-war activists painted it black. This was followed by a paint scuffle where the "A" was painted various colors until the city council intervened. It is now red, white and blue except when it is white or another color decided by a biennial election. Because of the three-color paint scheme often used, the shape of the A can be vague and indistinguishable from the rest of the peak. The top of Sentinel Peak, which is accessible by road, offers an outstanding scenic view of the city looking eastward. A parking lot located near the summit of Sentinel Peak was formerly a popular place to watch sunsets or view the city lights at night.

How did City Council decide to paint the A?
What is the answer?
ANS: red, white and blue
QUES: At the Battle of Pulo Aura, which was probably the company's most notable naval victory, Nathaniel Dance, Commodore of a convoy of Indiamen and sailing aboard the Warley, led several Indiamen in a skirmish with a French squadron, driving them off. Some six years earlier, on 28 January 1797, five Indiamen, the Woodford, under Captain Charles Lennox, the Taunton-Castle, Captain Edward Studd, Canton, Captain Abel Vyvyan, and Boddam, Captain George Palmer, and Ocean, Captain John Christian Lochner, had encountered Admiral de Sercey and his squadron of frigates. On this occasion the Indiamen also succeeded in bluffing their way to safety, and without any shots even being fired. Lastly, on 15 June 1795, the General Goddard played a large role in the capture of seven Dutch East Indiamen off St Helena.

Where were the 7 Dutch Easteast indiamen capture?
