A type is a user-specified object or collection definition. Oracle Application Express currently only supports collection definitions. There are two categories of Oracle collections (SQL collections):
Variable-length arrays (VARRAY types)
Nested tables (TABLE types)
VARRAY types are used for one-dimensional arrays, while nested table types are used for single-column tables within an outer table.
