You can adapt this file completely to your liking, but it should at least
contain the root `toctree` directive.
Welcome to dataset's documentation!
===================================

Simple API::
import dataset
# open a sqlite database (or create one if it doesn't exist yet)
db = dataset.connect('sqlite:///factbook.db')
# get a wrapper for the table 'population'
# this will create the table if it doesn't exist yet
table = db['population']
# insert a new row (and also create the columns if they don't exist yet)
table.insert(dict(country='China', year=2012, population=1354040000))
table.insert(dict(country='India', year=2011, population=1210193422))
# you can easily add new columns at any time
table.insert(dict(country='United States', year=2013, population=315591999, source='http://www.census.gov'))

Database
========
A Database is a simple wrapper around SQLAlchemy engines. Most of the time you want to use it to get instances to tables using *get_table* or the short-hand dict syntax::
# both statements return the same table
table = db['population']
table = db.get_table('population')
.. autoclass:: dataset.Database
:members: get_table, create_table, load_table, query
:undoc-members:
Table
=====
Using the *Table* class you can easily store and retreive data from database tables.
