Advantages of using relative dating

For example, in a Unicode database ( column that can store up to five Chinese characters together with five English characters.In byte semantics, this would require (5*3 bytes) (1*5 bytes) = 20 bytes; in character semantics, the column would require 10 characters.

The decimal is the character that separates the integer and decimal parts of a number.

If you specify a negative scale, Oracle Database rounds the actual data to the specified number of places to the left of the decimal point.

For example, specifying (7,-2) means Oracle Database rounds to the nearest hundredths, as shown in Table 26-1.

It also provides a way to represent privately-defined characters.

A database column that stores Unicode can store text written in any language.

For single byte character sets, columns defined in character semantics are basically the same as those defined in byte semantics.
