Includes components that encapsulate access to Cosmo data sources.

Package Specification

The interfaces in this package specify APIs for accessing and manipulating Cosmo model data. The interfaces are independent of underlying storage mechanisms (which are provided as subpackages).

Data access objects (DAOs) are typically not used by the application or protocol layer directly but rather by the service layer, which often uses multiple DAOs and applies server-wide "business logic" when performing a service operation.
