• Relational tables (principles)

Main teaching materials

• Slides used: http://tecfa.unige.ch/guides/te/files/mysql-intro.pdf
• Lecture notes (very similar to slides): SQL and MySQL tutorial

Classroom activities

Monday

• Define a table with SQL code
• Learn how to inject SQL code in MySQL Admin (a web application to administer web databases) in order to create databases and tables
• Create a simple 1-table MySQL database with the database administration tool

Play time

Warning. Be careful with quotes and double quotes.

• Quotes must be straight (same for double quotes).

 '  = Ok
 ’  = BAD !!!

... So use a real text editor and not a word processor.

(1) Demo 1 example

CREATE TABLE demo1 (
  id int(10) NOT NULL auto_increment,
  login char(10) DEFAULT '' NOT NULL,
  password char(100),
  fullname char(40) DEFAULT '' NOT NULL,
  url char(60) DEFAULT '' NOT NULL,
  food int(11) DEFAULT '0' NOT NULL,
  work int(11) DEFAULT '0' NOT NULL,
  love int(11) DEFAULT '0' NOT NULL,
  leisure int(11) DEFAULT '0' NOT NULL,
  sports int(11) DEFAULT '0' NOT NULL,
  PRIMARY KEY (id),
  KEY login (login)
);

(2) Student database with 2 tables

DROP TABLE IF EXISTS student;
DROP TABLE IF EXISTS exercise;

CREATE TABLE student (
  id int(10) NOT NULL auto_increment,
  name char(40) DEFAULT '' NOT NULL,
  first_name char(40) DEFAULT '' NOT NULL,
  PRIMARY KEY (id)
);

INSERT INTO student VALUES (NULL,'Testeur','Bill');
INSERT INTO student VALUES (NULL,'Testeur','Joe');
INSERT INTO student VALUES (NULL,'Testeuse','Sophie');

CREATE TABLE exercise (
  id int(10) NOT NULL auto_increment,
  title char(40) DEFAULT '' NOT NULL,
  student_id int(10) NOT NULL,
  comments varchar(128),
  url char(60) DEFAULT '' NOT NULL,
  PRIMARY KEY (id),
  KEY student_id (student_id)
);

INSERT INTO exercise VALUES (NULL,"Exercise 1",'1',"small comment",'http://tecfa.unige.ch/');
INSERT INTO exercise VALUES (NULL,"Exercise 2",'1',"no comment",'http://tecfa.unige.ch/');

Classroom activities Wednesday

• Continue creating a table (if needed)
• Relational databases with 2 or 3 tables (simple 1-N and N-N cases)
• Web hosting (discussion)
• The anatomy of Wordpress

Homework 3

Topic: Database definition (2-3 tables), Details to be announced on Wednesday.

Define an SQL file that will create 2-4 related tables. You can freely choose the application area, but it should somewhat relate to prior homework or the term project.

</source> Minimal requirements:

• 2 tables min. and 4 tables max. Make sure that the tables are related
• At least 10 fields (for all tables)
• At least 1 integer and 1 varchar (for all tables)
• Each table must define a primary key

The file must include some documentation on top that (1) explains the purpose of this database and of each table and that (2) provides some high-level design elements.

Remark:

• This homework is not related to the term project, but helps you preparing exams

Submission Dates

• This homework is due at start of wed week 4
• Students must upload the SQL file to the worldclassroom (don't forget the documentation inside this file).
• Each homework counts 10% in your global evaluation. The four best homeworks will be taken into account.

Evaluation

• See the worldclassroom

Teaching materials and further reading

Online software

• We shall use MoWes again

Teaching materials (slides and reading)

• Slides used: http://tecfa.unige.ch/guides/te/files/mysql-intro.pdf
• Lecture notes (very similar to slides): SQL and MySQL tutorial

You probably will have to complete my lecture notes with extra reading. Pick one of the following. (Unfortunately, some of these articles are presented as multiple pages ....)

• Introduction to Structured Query Language: Version 4.11 by James Hoffman. Good bet if you like concise texts.
• Getting Started With SQL by Ted Brockwood, Web developper's journal. Good as first introduction.
• SQLCourse and SQLCourse2
• Introduction to Databases for the Web: Pt. 1 by Selena Sol, database journal (good, but too many distracting ads)
