Move database methods to static and document database class (#6474)

* Add new static method to created newly connected database object

* Document database class and clean up and document some of the methods.
This removes the methods that should not be in each instance and places
them in the single instance class as to occupy less resources and be
able to create database objects more efficiently.

* More docs & removed the ability to set any value within the object.
