Custom data types allow for more intelligent application design, as data management tasks such as conversion or validation can be applied at this basic data level.
Define your own datatypes beyond the Java primitives.
Assign freely definable meta-tags to attributes to be used in higher levels of abstraction.
Relate datatypes to converters to decorate data with images or unleash the power of UOMo in a simple data entry field.
Relate datatypes to validation rules to enforce purity of data entry.
