Class Summary
ArrayCollectionMappingHelper Helper class to consolidate all the heinous comparing and merging code for the Array collection mappings.
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.
ObjectRelationalDatabaseField INTERNAL: A database field of object-relational type: either a java.sql.Array, java.sql.Struct, or java.sql.Ref.
ObjectRelationalDataTypeDescriptor Purpose: Differentiates 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.
