Explanation of Solution
Data-flow diagram:
- A data-flow diagram (DFD) is a diagram used during both the analysis and design phases to document the processes of the current system or to provide a model of a proposed new system.
- Structure of DFD starts from a broad overview and expand it to a hierarchy of detailed diagrams
Uses:
- It shows not only the various processes within the system but also where the data needed for each process comes from, where the output of each process will be sent, and what data will be stored and where.
- The DFD does not provide any information about the process timing (e...

Draw a system/level-0 diagram for this scenario: You are developing a new customer relationship management system for the BEC store, which rents out movies to customers. Customers will provide comments on new products, and request rental extensions and new products, each of which will be stored into the system and used by the manager for purchasing movies, extra copies, etc. Each month, one employee of BEC will select their favorite movie pick of that week, which will be stored in the system. The actual inventory information will be stored in the Entertainment Tracker system, and would be retrieved by this new system as and when necessary. Example of what a level-0 diagram looks like is attached.

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.
