    022 * <p>
    023 * Definition of a properties interface for parameters of a database configuration.
    024 * </p>
    025 * <p>
    026 * The properties defined by this interface are used to configure a {@code DatabaseConfiguration} instance. They mainly
    027 * specify the database tables containing configuration properties. Note that many properties are mandatory; they must
    028 * be provided, otherwise the builder for database configurations throws an exception.
    029 * </p>
    030 * <p>
    031 * <strong>Important note:</strong> This interface is not intended to be implemented by client code! It defines a set of
    032 * available properties and may be extended even in minor releases.
    033 * </p>
