Overview of $ModelTypes
Datatypes support the specification of scalar data types, structured datatypes, scales and code lists. Scalar datatypes include all of the ORACLE data types. Structured data types provide for the definition of arrays, lists and other composite data types. Code lists are used to specify enumerated values that need not be governed as reference data, such as status values.
You will not be asked to provide any inclusions for the a new Datatypes collection on create.
