Database:
- Database is the organized collection of related data elements that is used to keep the record or track the things or items of interest.
- It is often defined as the structure to hold the data.
- It contains the elements like schemas, views, tables (that are linked through foreign keys), queries, and many other elements.
- Database and database management are interdependent.
Explanation of Solution
Importance of database technology:
- The importance of database technology is increasing day by day as they are in use everywhere today.
- This acts as the most important part of e-commerce and other web based applications, and also a heart of organization-wide operational and decision support applications.
- It is said that databases are used by many work groups and individuals all over the world.
- Over 10 million databases are active in the world, which reflects the importance of database technology in today’s world.
Example:
| Student_id | Student_name | Student_branch |
| 11 | XXX | IT |
| 12 | YYYY | Civil |
| 13 | ZZZZ | Electrical |
| 14 | AAAA | Mechanical |
Explanation:
From the above table:
- “Student_id” specifies the unique id number of the student.
- “Student_name” specifies the name of students.
- “Student_branch” specifies the branch of the students.
Therefore, it is clear that recording the student data in such organized way will lead to a systematic management of organization or any other work groups.

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 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()).
