What reading level is Probabilistic Techniques for Two Phase Locking in Database Systems book?
To quickly assess the difficulty of the text, read a short excerpt:
For each r, let the r-lock response time T (where B specifies a fixed adverse r, D relative shift in time of the executions of the transactions and data modules programs) be the random variable qiving the length of the minimum time interval A required for any transaction module in i € TR to have r locks simultaneously granted, given that i requested the locks during the entire interval A . Let T^ = max mean(T, B) over all adverse shifts B. Let F_, (x) be the r r B, r probability distribution fu...nction of T _, , i. E. F_, (x) = Prob{T r^ l-e. R D, r r — 3. 2. A probabilistic 2PL method which uses random waits. Each data module i eD has, for each transaction module j G T ns. , a special binary flag F. . Whose value indicates if the lock L(i) is allocated to j . If j reads F. . And finds it 0, then it understands that it lost the lock. Module i has also another binary flaa W. . For each j e s. (W. . Is called a warnincr flag) .
