Driver Objects
3+
**************
4+
5+
A `Driver` object holds the detail of a Neo4j database including server URIs, credentials and other configuration.
6+
It also manages a pool of connections which are used to power :class:`.Session` instances.
7+
8+
The scheme of the URI passed to the `Driver` constructor determines the type of `Driver` object constructed.
9+
Two types are currently available: the :class:`.DirectDriver` and the :class:`.RoutingDriver`.
10+
These are described in more detail below.
