Aleph-naught (aleph-naught, also aleph-zero or the German term Aleph-null) is the cardinality of the set of all natural numbers, and is an infinite cardinal. The set of all finite ordinals, called Ï or Ï 0 (where Ï is the lowercase Greek letter omega), has cardinality .
NULL means no value as in unassigned. An object that is not instantiated should be . In databases NULL means unassigned = no value It is different from 0 which is a value. null (or NULL in some languages, but I will use the lowercase version for simplicity) is the value that a pointer has when it is considered to 'point to nothing'. I believe in languages like C and C++, null is defined as equal to the integer 0. So technically speaking, a null pointer would point to memory address 0.
