Normalization

Create Table and Constraints

• CREATE TABLE `village` ( `vill_id` int(11) NOT NULL, `vill_moo` varchar(10) DEFAULT NULL, `vill_name` varchar(100) DEFAULT NULL, `tambon_tam_id` char(10) NOT NULL, PRIMARY KEY (`vill_id`), foreign key (tambon_tam_id) references tambon(tam_id)) ENGINE=innodb DEFAULT CHARSET=utf8;

Sync Workbench with DBUpdate model

Now We got an updated Model

• Don’t forget to drag a new table into a new model

Week-1

• Lecture• Reviews of Database Management Systems– SQL and Query Evaluation

• Lab– From Spreadsheets to the Web

Week-1:Lecture

• Reviews of Database Management Systems– SQL and Query Evaluation

• Introduction• Data Modeling• SQL

Exercise

• Let’s create an E-R for the following data (using a SQL statement)

39

Create a table

Show create table village

Village-ER

Village-ER => Normalization?

Village-ER => Normalization?

Why do we need normalization?

Village-ER => Normalization?

Now we need to populate the data

Week-1-Lab

• From Spreadsheets to the Web1. Spreadsheets (MSExcel) to Relational DB

(MySQL)2. MySQL to Web (PHP)3. Web (PHP) to WebService (Google Map)

Pre-requisite

• You need to have the following applications on your machine– Your local Web server (appserv)– Your IDE (Eclipse)– Mysql workbench

• Internet

Your local Web server (appserv)

• If you use appserv 2.6.x you might have a problem about calling phpMyAdmin

• You need to make a call to 127.0.0.1 instead• And you need to change the config file and

reboot

From Spreadsheets to the Web

1. Spreadsheets (MSExcel) to Relational DB (MySQL)

1. Let’s see Thai version created by my advisees.

Villages in ChiangMai

In CVS

Use MySQL workbench to create your database

Create Your Database

Some time you need to synchronize your model with your localhost

Output at localhost

Let’s import data from excel

Error Why?

Wrong Selection => Select your table

Now Select a file to import

Error Again

Choose the right option

Don’t forget to set your encoding

Choose the right option

Week-1-Lab

• From Spreadsheets to the Web1. Spreadsheets (MSExcel) to Relational DB

(MySQL)2. MySQL to Web (PHP)3. Web (PHP) to WebService (Google Map)

PHP Code

Output

Your turn: I want sub_district_name

1. No duplicate

Your turn: I want sub_district_name

1. No duplicate

select distinct sub_district_namefrom village;
