Program Plan Intro

Pessimistic locking:

It is one of the locking methods in concurrency control. The lock exists in the transaction until the transaction gets committed or rolled back.

Two-phase locking protocol:

It defined the serializability of the transaction but not prevent deadlocks. The process of locking and unlocking can be done using two phases in this protocol. They are: Growing phase and shrinking phase.

Growing phase:

New lock can be occurred on the transaction without unlocking the data items. The data items are locked in this phase.

Shrinking phase:

This phase used to release all transaction but not provide new lock on the transaction.

Row-level lock granularity:

This row-level locking process used to lock the single row in the table. It is used to improve the availability of data and involving in transaction conflict.

Prove for each pair of expression f(n) and g(n) whether f(n) is big O, little o Ω,ω or Θ of g(n). Use limits to find these. For each case it is possible that more than one of these conditions is satisfied:1. f(n) =log(n2^n), g(n) = log(sqrt(n)2^(n^2))2. f(n) =nsqrt(n) +log(n^n), g(n) =n + sqrt(n)logn
