Step 1: Database Schema
=======================

First we want to create the database schema.  For this application only a
single table is needed and we only want to support SQLite so that is quite
easy.  Just put the following contents into a file named `schema.sql` in
the just created `flaskr` folder:

.. sourcecode:: sql

    drop table if exists entries;
    create table entries (
      id integer primary key autoincrement,
      title string not null,
      text string not null
    );

This schema consists of a single table called `entries` and each row in
this table has an `id`, a `title` and a `text`.  The `id` is an
automatically incrementing integer and a primary key, the other two are
strings that must not be null.
