# EIS Composite Object Mapping

An EIS composite object mapping maps a Java object to a privately owned one-to-one relationship in an EIS record according to its descriptor's record type, as shown in Table 56-4.

Table 56-4 EIS Composite Object Mapping by EIS Record Type

EIS Record Type | Mapping Behavior
--- | ---
Indexed | Maps directly to a subrecord in the indexed recordFoot 1 .
Mapped | Maps directly to a subrecord in the mapped recordFootref 1.
XML | Maps directly to an attribute or text node in the XML recordFoot 2 .

Footnote 1 See also "Composite EIS Mappings".

Footnote 2 See also "XML Composite Object Mapping".

Figure 56-6 illustrates a composite object EIS mapping between `Order` class attribute `address` and an XML record. `Order` attribute `address` is mapped to an XML record composed of an `order` element that contains an `address` element.
