- { Create, Insert, Update } Syntax will be changed.

Built-In Data Types
||Data Type||Explanation|| 
|BOOLEAN|Stores the Boolean values for true and false|
|BYTE|Stores binary data that are not random access|
|CHAR(*n*)|Stores single-byte or multibyte sequences of characters, including letters, numbers,
and symbols of fixed length Collation is code-set dependent|
|VARCHAR(*m*,*r*)|Stores single-byte or multibyte strings of letters, numbers, and symbols
of varying length to a maximum of 255 bytes Collation is code-set dependent|
|DECIMAL|Stores numbers with definable scale and precision|
|INTEGER or INT|Stores a span of time|
|SMALLINT|Stores whole numbers from -(215-1) to 215-1|
|INT8|Stores an 8-byte integer value These whole numbers can be in the range -(263-1) to 263-1|
|SERIAL|Stores sequential integers; has the same range of values as INTEGER|
|SERIAL8|Stores large sequential integers; has the same range of values as INT8|
|TEXT|Stores text data in chunks that are not random access|

|DECIMAL|Stores numbers with definable scale and precision|
|INT|Is a synonym for INTEGER|
|INT8|Stores an 8-byte integer value These whole numbers can be in the range -(263-1) to 263-1|
|INTEGER|Stores a span of time|
|REAL|Is a synonym for SMALLFLOAT|

> A built-in data type is a fundamental data type that the hbase shell defines.
> (character strings, scalars, ranges, arrays, ... , etc)
> If you need a specialized data type that is not currently provided as a built-in type,

> you are encouraged to write your own user-defined data type using UDC(not yet implemented).
> (or contribute it for distribution in a future release of hbase shell)
