Chapter 7 Database Concepts NCERT Book Class 11

7.1 Introduction
After learning about importance of data in the previous chapter, we need to explore the methods to store and manage data electronically. Let us take an example of a school that maintains data about its students, along with their attendance record and guardian details.
The class teacher marks daily attendance of the students in the attendance register. The teacher records ‘P’ for present or ‘A’ for absent against each student’s roll number on each working day.
If class strength is 50 and total working days in a month are 26, the teacher needs to record 50 × 26 records manually in the register every month. As the volume of data increases, manual data entry becomes tedious. Following are some of the limitations of manual record keeping in this example:
1) Entry of student details (Roll number and name)
in the new attendance register when the student is promoted to the next class.
2) Writing student details on each month’s attendance page where inconsistency may happen due to incorrectly written names, skipped student records, etc.
3) Loss of data in case attendance register is lost or damaged.
4) Erroneous calculation while consolidating attendance record manually.
The office staff also manually maintain Student details viz. Roll Number, Name and Date of Birth with respective guardian details viz. Guardian name, Contact Number and Address. This is required for correspondence with guardian regarding student attendance and result.
Finding information from a huge volume of papers or deleting/modifying an entry is a difficult task in pen and paper based approach. To overcome the hassles faced in manual record keeping, it is desirable to store attendance record and student details on separate data files on a computerized system, so that office staff and teachers can:
1) Simply copy the student details to the new attendance file from the old attendance file when students are promoted to next class.
2) Find any data about student or guardian.
3) Add more details to existing data whenever a new student joins the school.
4) Modify stored data like details of student or guardian whenever required.
5) Remove/delete data whenever a student leaves the school.
