Answer:
In database software a record is a group of related data held within the same structure.
Answer:
Big Oh notation is used to asymptotically bound the growth of running time above and below the constant factor.
Big Oh notation is used to describe time complexity, execution time of an algorithm.
Big Oh describes the worst case to describe time complexity.
For the equation; T(N) = 10000*N + 0.00001*N^3.
To calculate first of all discard all th constants.
And therefore; worst case is the O(N^3).

Answer:
Option 2: Variable names can not begin with a number.
Explanation:
As given Mark and John named a variable as 24_hour_mart while writing a program in python.
While it is forbidden to name a variable starting with any digit, only alphabets (capital and smaller) and underscore can be the first letter of the variable name.
Moreover, by considering the other options given:
- Variable name can include the underscore (_) between the words. It is used instead of spaces that are not allowed.
- There is no upper limit for variable length, it can be of any reasonable length and more than 10 characters say 11 or 12 are reasonable.
- There is no lower limit for variable length, it can be any reasonable length , even it can be of 1 character.
Variables named in python language must not be the keywords as they are reserved for other purposes.
