A NHibernate any type.

An array has a primary key consisting of the key columns + index column

A bag permits duplicates, so it has no primary key

Base class that stores the mapping information for <array>, <bag>, <id-bag>, <list>, <map>, and <set> collections.

Represents the mapping to a column in a database.

The mapping for a component, composite element, composite identifier, etc.

Base class for relational constraints in the database.

A Foreign Key constraint in the database.

A formula is a derived column value.

An PersistentIdentifierBag has a primary key consistenting of just the identifier column.

A collection with a synthetic "identifier" column.

An Index in the database.

Indexed collections include IList, IDictionary, Arrays and primitive Arrays.

A list has a primary key consisting of the key columns + index column

A map has a primary key consisting of the key columns + index columns.

A meta attribute is a named value or values.

A mapping for a one-to-many association.

A mapping for a one-to-one association.

Base class for the RootClass mapped by <class> and a Subclass that is mapped by <subclass> or <joined-subclass>.

A Primary Key constraint in the database.

A primitive array has a primary key consisting of the key columns + index column.

Mapping for a property of a .NET class (entity or component).

Declaration of a System.Type mapped with the <class> element that is the root class of a table-per-sublcass, or table-per-concrete-class inheritance heirarchy.

A Set with no nullable element columns will have a primary key consisting of all table columns (ie - key columns + element columns).

Any value that maps to columns.

Declaration of a System.Type mapped with the <subclass> or <joined-subclass> element.

Represents a Table in a database that an object gets mapped against.

A simple-point association (ie. a reference to another entity).

An Unique Key constraint in the database.

Any mapping with an outer-join attribute

Defines mapping elements to which filters may be applied.

Represents an identifying key of a table: the value for primary key of an entity, or a foreign key of a collection or join table or joined subclass table.

Operations to create/drop the mapping element in the database.

A value is anything that is persisted by value, instead of by reference. It is essentially a Hibernate IType, together with zero or more columns. Values are wrapped by things with higher level semantics, for example properties, collections, classes.

Indicates whether given properties are generated by the database and, if so, at what time(s) they are generated.
