 Working with Databases
 ======================
 
-> Note: This section is under development.
-
 In this section, we will describe how to create a new page to display data fetched from a database table.
-To achieve this goal, you will create an [action](structure-controllers.md), a [view](structure-views.md),
-and an [Active Record](db-active-record.md) model that can be used to fetch and represent database data.
+To achieve this goal, you will configure the database connection, create an [Active Record](db-active-record.md) class
+to fetch and represent database data, and then create an [action](structure-controllers.md) and
+a [view](structure-views.md) to present the data to end users.
 
 Through this tutorial, you will learn
 
-* How to configure database connections;
+* How to configure DB connections;
 * How to define an Active Record class;
 * How to query data using the Active Record class;
 * How to display data in a view in a paginated fashion.
 
+Note that in order to finish this section, you should have basic knowledge and experience about databases.
+You should know how to create a database and how to execute SQL statements using a DB client tool.
+
+
+Configuring a Database Connection
+---------------------------------
+
+To start, you should have a database ready. It can be a SQLite, MySQL, PostgreSQL, MSSQL or Oracle database.
+For simplicity, in the following description, we will assume that you already have a MySQL database named `basic`.
+
+Create a table named `address` and insert some sample data. The SQL statements are showing as follows,
+
+```sql
+CREATE TABLE `address` (
+    `id`       int(11) NOT NULL AUTO_INCREMENT,
+    `street`   varchar(128),
+    `city`     varchar(128),
+    `state`    varchar(128),
+    `country`  varchar(128)
+);
+```

 Working with Forms
 ==================
 
-> Note: This section is under development.
-
 In this section, we will describe how to create a new page to get data from users.
 The page will display a form with a name input field and an email input field.
 After getting these data from a user, the page will echo them back to the user for confirmation.
