What to Focus On

  • Manual attendance recording becomes tedious as data increases.
  • A class of 50 students over 26 working days needs 1300 manual attendance entries per month.
  • Manual systems can lead to loss of data and calculation errors.

  • Difficulty in access is a limitation of the file system.
  • Redundancy means same data are duplicated in different places.
  • Inconsistency means duplicated data do not match.

  • DBMS is software used to create and manage databases.
  • DBMS works as an interface between users and the database.
  • Database engine handles creation, retrieval, and manipulation.

Common Mistakes to Avoid

A foreign key is the same as a primary key.

RollNumber alone is the primary key of ATTENDANCE.

Any attribute with repeated values cannot be a key.
