Expert Solution & Answer
Program Plan Intro
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.
