What to Focus On

  • A file stores data in a computer.
  • Redundancy means duplicate storage of the same data in different files.
  • Inconsistency occurs when duplicate data do not match.
  • DBMS is software for creating and managing databases.
  • DBMS hides storage details and gives an abstract view of data.
  • Querying means requesting data in a desired way.
  • STUDENT and ATTENDANCE are related through RollNumber.
  • SName is removed from ATTENDANCE in the database version.
  • GUARDIAN is created to avoid repeated guardian details.

Common Mistakes to Avoid

Database schema and database instance mean the same thing.

Degree means the number of rows and cardinality means the number of columns.

RollNumber alone is the primary key of ATTENDANCE.

Memory Tips
