Anything protected by the copyright law has a legal concept that grants artists or authors control over their creations. On the other hand, anything in the public domain is not protected by intellectual property laws and the public owns these works.

Clearly explain with five differences between high level programming language, interpreted language and a machine language.

Anna11 [10]

Answer:

Execution Time, Memory storage,Readiability,

debugging,Platform independent

Explanation:

High level programming languages are the language which is user friendly languages. There is high level abstraction from internal machine code. Here we need compiler to translate that into machine code

Ex: C,c++,Java...

Interpreted languages are scripting languages where we need interpreter to interpret those scripts or commands

Ex:Python.Ruby

Machine languages are binary language which contains 0's and 1's can understandable by system only. Not human readable forma

Interpreted language scans each statement at a time and interprets that line by line. It takes less amount of time to analyze the source code but the overall execution time is slower.

High level language takes more memory than interpreted and machine as it generates some intermediate code

High level languages are more readable than remaining two

Intermediate languages are easy to debug as it executes line by line and when ever any error occurs in a particular line it stops and intimate there itself

High level and interpreted languages are platform dependent, it can work on some machine and OS specific configurations only

What is a foreign key and how does it provide referential integrity?

Step2247 [10]

Answer:

By definition a foreign key of table A is a primary key of another table B, thereby establishing a link between them.

To provide referential integrity you can use these referential actions:

Cascade: If rows in table B are deleted, the matching foreign key columns in table A are deleted.

Set Null: If rows in table B are deleted, the matching foreign key columns in table A are set to null.

Set Default: If rows in table B are deleted, the matching foreign key columns in table A are set with the default value of the column.

Restrict: A value in table B cannot be deleted or updated while as it is referred to by a foreign key in table A.
