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:
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.
