THREE LEVELS OF DATA INDEPENDENCE

THREE LEVELS OF DATA INDEPENDENCE It divides the entire system into three inter-related but independent modules: Physical Level: Here, information about the location of database objects in the data store is kept. Various DBMS users are unaware of the locations of these objects. The Physical level of database describes how the data is stored in secondary storage devices such as disks and tapes. Conceptual Level: Here, data is represented in the form of various tables. For Example, STUDENT database may contain NAME and COURSE tables, but the users are unaware of their storage. It refers to what kind of data to be stored in a database. External Level: Here, it specifies the view of data in terms of conceptual level tables. It can generate different views of the database for different users. It focuses main on data abstraction.  Data Independence: It means change of data at one level must not affect the another level. Physical Data Independence: Any change in the physical location of the t

Problem Print a list of all possible coordinates given by (i,j,k) on a 3D grid where the sum of i+j+k is not equal to  n. Here, 0<=i<=x;0<=j<=y;0<=k<=z. Please use list comprehensions rather than multiple loops, as a learning exercise.  Source Code   if  __name__ ==  '__main__' :     x =  int ( input ())     y =  int ( input ())     z =  int ( input ())     n =  int ( input ())      print   ([[ a , b , c ]   for  a  in   range ( 0 , x+1 )   for  b  in   range ( 0 , y+1 )   for  c  in   range ( 0 , z+1 )     if  a + b + c != n  ])
