    Description
    A class that encapsulates the Column name and data type of a column in a relational table.
    This is the internal representation of a database key.
    A DbMapping describes how a certain type of Nodes is to mapped to a relational database table.
    This class describes a releational data source (URL, driver, user and password).
    An interface for objects that generate IDs (Strings) that are unique for a specific type.
    This is the interface for the internal representation of an object key.
    This is the internal representation of a database key with multiple columns.
    An implementation of INode that can be stored in the internal database or an external relational database.
     
    This class is a handle or reference to a Node.
    The NodeManager is responsible for fetching Nodes from the internal or external data sources, caching them in a least-recently-used Hashtable, and writing changes back to the databases.
    This class describes a parent relation between releational nodes.
    A property implementation for Nodes stored inside a database.
    This describes how a property of a persistent Object is stored in a relational database table.
     
    Container implementation for subnode collections.
    This is the internal key for an object that is not - or not directly - fetched from a db, but derived from another object.
