Step 1: Database SchemaΒΆ

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.
