db.run('CREATE TABLE IF NOT EXISTS `Artist` ( ' +
'`id` INTEGER NOT NULL, ' +
'`name` TEXT NOT NULL, ' +
'`date_of_birth` TEXT NOT NULL, ' +
'`biography` TEXT NOT NULL, ' +
'`is_currently_employed` INTEGER NOT NULL DEFAULT 1, ' +
'PRIMARY KEY(`id`) )');
db.run('CREATE TABLE IF NOT EXISTS `Series` ( ' +
'`id` INTEGER NOT NULL, ' +
'`name` TEXT NOT NULL, ' +
'`description` TEXT NOT NULL, ' +
