- Generally spreadsheets are also used to track things, the circumstance where a database is preferred with spreadsheets are when more information needs to processed to obtain a certain decision.
- Spreadsheets are limited when more details regarding the data collected needs to be added.
- In that case, database are preferred when more data needs to be added to calculate.
Determining database as a better choice:
Managing hundreds of spreadsheet with huge amount of data is really a tedious process for the manager.
- The data that are present in the spreadsheet can be used in an effective way with the help of queries.
- The data contents that are present in the database are processed based on the query, can be protected from the malicious user and data gets stored permanently into the database and the chance of data being lost gets reduced.
Therefore, the choice of using database is recommended in the solving the problems stated.
Developing the database as a centralized database:

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. The main method prints the sum and average based on the result returned from findSumAndAverage()).
