Contains classes that define an object model and instantiate it in a standard form analytic workspace.
The object model is composed of base objects that define a cube or a cube component. Most objects are owned by a parent object. For example, a measure is owned by its parent cube, and a level is owned by its parent dimension. Cubes, measures, dimensions, and dimension components can include mapping information for populating them with data from relational tables. A calculation model specifying aggregation, allocation, and forecasting can be applied to measures.
Cubes, Dimensions, and Solve Definitions are top-level objects in the object model hierarchy. Cubes and Dimensions exist within a schema. Cubes, Dimensions, and Solve Definitions may be associated with an analytic workspace.

OLAP Analytic Workspace API Object Model
For more information on the logical model for OLAP and standard form analytic workspaces, see the Oracle OLAP Application Developer's Guide.
The oracle.AWXML package contains three base classes:
AWConnection class, which establishes a JDBC connection and executes Database commands to instantiate an object model in an analytic workspaceBaseObject class, which represents the object model. Each BaseObject instance has methods for creating, deleting, and modifying the object in an OLAP session that uses a JDBC connection. Each BaseObject instance also has methods that can serialize the model as XML.AWHandlerBase class, which parses stored XML and restores it as Java objects in memory.All the other classes in the oracle.AWXML package are subclasses of BaseObject.
