Detailed Description

Type properties, used to collect type information for later assignment to an Item object.

The object stores attributes signedness, max length and collation. However, precision and scale (for decimal numbers) and fractional second precision (for time and datetime) are not stored, since any type derived from this object will have default values for these attributes.
