EIS Composite Collection Mappings map a java.util.Map or java.util.Collection of Java objects
to an EIS record in a privately owned, one-to-many relationship according to its descriptor's
record type.
EIS Composite Direct Collection Mappings map a collection of simple Java attributes
to and from an EIS Record according to its descriptor's record type.
EIS Composite Object Mappings map a Java object to a privately owned, one-to-one
relationship to an EIS Record according to its descriptor's record type.
An EIS one-to-many mapping is a reference mapping that represents the relationship between
a single source object and a collection of mapped persistent Java objects.
An EIS one-to-one mapping is a reference mapping that represents the relationship between
a single source object and a single mapped persistent Java object.
EIS Transformation Mappings allow the creation of custom mappings where one or more fields
in an EIS Record can be used to create the object to be stored in a Java class's attribute.
