A classifier is an element that describes structural and behavioral features;
it comes in several specific forms, including class, data type, interface,
component, and others that are defined in other metamodel packages.
DeploymentGroup represents a logical grouping of model elements defining
a single, complete deployment of an instance of Olap Schema (i.e.,
CubeDeployments and DimensionDeployments).
A Dimension is an ordinate within a multidimensional structure, and consists
of an ordered list of values (i.e., members) that share a common
semantic meaning within the domain being modeled.
Dimension represents physical dimension in a multidimensional database (e.g.,
a dimension object defined by the programming model/API of an OLAP database
server).
Each instance of Extent owns a collection of instances and is used to link
such collections to their structural and behavioral definitions in CWM
Resource packages.
The FeatureNode class represents ExpressionNode instances that are features
(i.e., attributes or operations) of some Classifier instance within
the CWM.
The FeatureSlot association connects Slot instances with the StructuralFeature
instance (usually either an Attribute or AssociationEnd instance) describing
the structure of the value held by the Slot.
A Hierarchy is an organizational structure that imposes a parent/child ordering
on the members of the Dimension, usually to define either a navigational
or consolidation/computational paths through the Dimension (i.e.,
a value associated with a child member is aggregated into one or more parents).
HierarchyLevelAssociation is a class that orders Levels within a LevelBasedHierarchy,
and provides a means of mapping Level/Hierarchy-oriented Dimension attributes
to one or more physical deployments.
If true, then the CubeRegion content is read-only (i.e., may not
be written or updated through the CubeRegion -- e.g., a CubeRegion
implemented via an SQL view may not permit updates to the underlying base
table).
isReadOnly() -
Method in interface org.omg.cwm.resource.relational.View
Indicates whether the underlying tables can be updated through an update
to this View.
isSystem() -
Method in interface org.omg.cwm.resource.relational.Table
Indicates that the Table is a System Table (generally part of or view on
the system catalog).
isTemporary() -
Method in interface org.omg.cwm.resource.relational.Table
The ObjectModel Core metamodel depends on no other packages, and contains basic
metamodel classes and associations used by all other CWM metamodel packages,
including other ObjectModel packages.
The ObjectModel's Instance metamodel allows the inclusion of data instances
with the metadata, since in addition to the metadata normally interchanged with
CWM, it is sometimes useful to interchange specific data instances as well.
The RangeMultiplicity association identifies the set of MultiplicityRange
instances that specify the lower and upper bounds of individual cardinality
ranges defined by a Multiplicity instance.
If true, then the CubeRegion content is read-only (i.e., may not
be written or updated through the CubeRegion -- e.g., a CubeRegion
implemented via an SQL view may not permit updates to the underlying base
table).
The stereotype concept provides a way of branding (classifying) model elements
so that they behave as if they were instances of new virtual metamodel
constructs.
