LenKa [72]

Answer:

The factorial of 3=6

Explanation:

Following are the description of the given question

  • This is JavaScript code .Here items are the variable that are holding the integer value "3".
  • After that there is 2 loop are iterating one is outer and one inner loop.
  • When i=1 1<=3 the condition of outer loop is true  the control moves the inner loop .
  • In the inner loop there is variable result that is initialized by 1 Now checking the condition of inner loop j=i i.e j=1 1>=1 condition of inner loop is true it executed the statement inside the inner loop  so result =1 .Now we increment the value of i of the outer loop.
  • i=2 2<=3 the condition of outer loop is true  the control moves the inner loop .
  • In the inner loop there is variable result that is initialized by 1 Now checking the condition of inner loop j=i i.e j=2 2>=1 condition of inner loop is true it executed the statement inside the inner loop  so result =2 .Now we increment the value of i of the outer loop.
  • Now i=3 3<=3 the condition of outer loop is true  the control moves the inner loop .
  • In the inner loop there is variable result that is initialized by 1 Now checking the condition of inner loop j=i i.e j=3 3>=1 condition of inner loop is true it executed the statement inside the inner loop  so result =6 .Now we increment the value of i of the outer loop.
  • i=4 4<=3 the condition of outer loop is false  the control moves from  the outer loop.
  • It print The factorial of 3=6

____ is a consistent relational database state in which every foreign key value also exists as a primary key value.​ a. ​ Refere
maria [59]

Answer:

The correct answer is Option A (Referential integrity)

Explanation:

When a relational database table is in ​first normal form, that means it has no repeating fields or groups of fields, and hence all rows have the same columns, while if a relational database table is in second normal form, it implies that every non-key field is functionally dependent on the primary key. If can be in the third normal form if no non-key field is functionally dependent on any other non-key field.​

A relational database on its own is a universal approved database model whose data is stored in tables divided into records and fields that serve as an information unit that organizes data points for easy access.

In the relational database, foreign keys are being checked to reference the primary key and enforce referential integrity so as to ensure that the foreign key must have a matching primary key. It means the reference from a row in one table to another table must be valid. Referential integrity concerns the concept of a foreign key normally enforced by the database management system.
