Computers and Technology

Gala2k [10]1 year ago
5 0

The association between tables is referred to as referential integrity. A primary key is required for each table in a database and can appear in other tables as a result of its connection to the data in those other tables. Foreign keys are used when a primary key from one table appears in another table.

  • In the second block, if the value in between 80-89. It will print B+.
  • In the third block, if value in between 70-79. It will print B.
  • In the fourth block, if value in between 60-69. It will print C+.
  • In the fifth block, if value in between 50-59. It will print C.
