Concept explainers

Concurrency Control

The simultaneous occurrence of two or more operations is called concurrence and the situation is called concurrency. In concurrency, the function of one operation can affect the function of the other and put data integrity at risk. Hence, management for the control of concurrency is required. The management or controlling system in the Database Management System (DBMS) that coordinates concurrent access is called the concurrency control system.

For a dictionary attack on a target server that didn't employ salt, you had previously prepared a file. Except for "impossible," the 171,000 words in this file make up the entire OED. The dictionary can no longer be used due to a 32-bit salt server upgrade. Instead of using brute force to sift through an outdated vocabulary, you should establish a brand-new one. How many total entries does the new dictionary have?

For a server that doesn't implement salt, you had earlier prepared a file to utilize in a dictionary attack. After you remove "impossible" from this file, you'll have the whole OED, which totals 171,000 words. The dictionary is unusable since the salt server was upgraded from 32 bits. Instead of using brute force to push your way through an outdated vocabulary, you should focus on creating a whole new one. How many words are there in the new dictionary altogether?
Assume that you have an empty buffer pool of size 4 pages and will access this access patternin the given order: RDBMSTHEORY.
