Class Summary |
ArrayMapping |
Purpose:
In an object-relational data model, structures can contain "Arrays" or collections of other data-types. |
NestedTableMapping |
Purpose:
Nested tables are similar to VARRAYs except internally they store their information in a separate table
from their parent structure's table. |
ObjectArrayMapping |
Purpose:
In an object-relational data model, structures can contain "Arrays" or collections of other data-types. |
ObjectRelationalDescriptor |
Purpose:
Differenciates object-relational descriptors from normal relational descriptors. |
ReferenceMapping |
Purpose:
In an object-relational data model, structures reference each other through "Refs"; not through foreign keys as
in the relational data model. |
StructureMapping |
Purpose:
A structure is an object-relational user-defined data-type or object-type. |
