    provides access to a configuration database composed of one or more

    <p> Configuration data is organized into layers which are selected 
        by components and entities.

    <p> Components are characterized by configuration schemas. 
        A component contains configuration data for a particular 
        application domain or software module.

    <p> Entities are organised hierarchically in organisations,
        groups, roles and individual users. Each element of the associated 
        hierarchy corresponds to a layer that applies to an entity.
    </p>
    <p> A layer contains data for multiple components 
        associated to a single entity.
