Chapter 17, Problem 5PE
Explanation of Solution
Conflict serializable schedule:
- A schedule is said to be serializable when it can be transformed to a serial schedule by swapping non-conflicting operations.
- Two operations are said to be conflicting if all they satisfies the conditions,
- They belong to different transactions.
- They operates on the same data item.
View Serializable schedule:
- The view serializability is the process of checking that the given schedule is view serializable or not.
- To check whether a given schedule is view serializable, we need to check whether the given schedule is View Equivalent to its serial schedule.
- The need of the view serializability is that non-serial schedule can leave the
database in inconsistent state...

The main() method asks the user to provide the dimension n for a square matrix. A square matrix has an equal number of rows and columns. b. The main() method receives the value of n and calls the matrixSetUp() method that creates a square matrix of size n and populates it randomly with integers between 1 and 9. c. The main method then calls another method named printMatrix() to display the matrix in a matrix format. d. The main method also calls a method named findSumAndAverage() which: • Receives the generated matrix as input. • Calculates the sum of all elements in the matrix. • Calculates the average value of the elements in the matrix. • Stores these values (sum and average) in a single-dimensional array and returns this array • e. The main method prints the sum and average based on the result returned from findSumAndAverage()). Enter the dimension n for the square…arrow_forward
