Depending on the semantic category, you must set one or more of the following native type properties:
Maximum precision
Minimum precision
Default precision
Support for changes to precision
Maximum scale
Minimum scale
Default scale
Support for changes to scale
Unit of length, such as characters, bytes, and bits
For Gregorian date semantics, support for hour, minute, second, year, month, day, or time zone
For float semantics, radix of the precision and exponent
Set the maximum and minimum values for precision and scale to validate the following:
Imported database metadata
Data type of a column that an end user adds to a table in a mapping
The default precision, default scale, and the specification of whether the precision and scale can be modified apply to metadata that is manually defined by the user. If the precision or scale cannot be modified, then the default value and the maximum value must be set to the same value.
