What BigInt 11?
The largest negative value for an integer is -2147483648 which is 11 characters and hence the default display width is 11. Similarly for BIGINT the default display width is 20 which is equal to the number of characters in the largest negative BIGINT (-9223372036854775808).

What is short data type?
short: The short data type is a 16-bit signed two’s complement integer. It has a minimum value of -32,768 and a maximum value of 32,767 (inclusive). As with byte , the same guidelines apply: you can use a short to save memory in large arrays, in situations where the memory savings actually matters.
