+Database Migration
+==================
+
+Like source code, the structure of a database is evolving as we develop and maintain
+a database-driven application. For example, during development, we may want to
+add a new table; or after the application is put into production, we may realize
+the need of adding an index on a column. It is important to keep track of these
+structural database changes (called **migration**) like we do with our source
+code. If the source code and the database are out of sync, it is very likely
+the whole system may break. For this reason, Yii provides a database migration
+tool that can keep track of database migration history, apply new migrations,
+or revert existing ones.
+
+The following steps show how we can use database migration during development:
+
+1. Tim creates a new migration (e.g. create a new table)
+2. Tim commits the new migration into source control system (e.g. GIT, Mercurial)
+3. Doug updates from source control system and receives the new migration
+4. Doug applies the migration to his local development database
+
+
+Yii supports database migration via the `yiic migrate` command line tool. This
+tool supports creating new migrations, applying/reverting/redoing migrations, and
+showing migration history and new migrations.
+
+Creating Migrations
+-------------------
+
+To create a new migration (e.g. create a news table), we run the following command:
+
+~~~
+yiic migrate/create <name>
+~~~
+
+The required `name` parameter specifies a very brief description of the migration
+(e.g. `create_news_table`). As we will show in the following, the `name` parameter
+is used as part of a PHP class name. Therefore, it should only contain letters,
+digits and/or underscore characters.
+
+~~~
+yiic migrate/create create_news_table
+~~~
+
+The above command will create under the `protected/migrations` directory a new
+file named `m101129_185401_create_news_table.php` which contains the following
+initial code:
+
+~~~
+[php]
+class m101129_185401_create_news_table extends \yii\db\Migration
+{
+	public function up()
+	{
+	}
+
+	public function down()
+	{
+		echo "m101129_185401_create_news_table cannot be reverted.\n";
+		return false;
+	}
+}
+~~~
+
+Notice that the class name is the same as the file name which is of the pattern
+`m<timestamp>_<name>`, where `<timestamp>` refers to the UTC timestamp (in the
+format of `yymmdd_hhmmss`) when the migration is created, and `<name>` is taken
+from the command's `name` parameter.
+
+The `up()` method should contain the code implementing the actual database
+migration, while the `down()` method may contain the code reverting what is
+done in `up()`.
+
+Sometimes, it is impossible to implement `down()`. For example, if we delete
+table rows in `up()`, we will not be able to recover them in `down()`. In this
+case, the migration is called irreversible, meaning we cannot roll back to
+a previous state of the database. In the above generated code, the `down()`
+method returns `false` to indicate that the migration cannot be reverted.
+
+As an example, let's show the migration about creating a news table.
+
+~~~
+[php]
+class m101129_185401_create_news_table extends \yii\db\Migration
+{
+	public function up()
+	{
+		$this->db->createCommand()->createTable('tbl_news, array(
+			'id' => 'pk',
+			'title' => 'string NOT NULL',
+			'content' => 'text',
+		))->execute();
+	}
+
+	public function down()
+	{
+		$this->db->createCommand()->dropTable('tbl_news')->execute();
+	}
+}
+~~~
+
+The base class [\yii\db\Migration] exposes a database connection via `db`
+property. You can use it for manipulating data and schema of a database.
+
+Transactional Migrations
+------------------------
+
+While performing complex DB migrations, we usually want to make sure that each
+migration succeed or fail as a whole so that the database maintains the
+consistency and integrity. In order to achieve this goal, we can exploit
+DB transactions.
+
+We could explicitly start a DB transaction and enclose the rest of the DB-related
+code within the transaction, like the following:
+
+~~~
+[php]
+class m101129_185401_create_news_table extends \yii\db\Migration
+{
+	public function up()
+	{
+		$transaction=$this->getDbConnection()->beginTransaction();
+		try
+		{
+			$this->db->createCommand()->createTable('tbl_news, array(
+				'id' => 'pk',
+				'title' => 'string NOT NULL',
+				'content' => 'text',
+			))->execute();
+			$transaction->commit();
+		}
+		catch(Exception $e)
+		{
+			echo "Exception: ".$e->getMessage()."\n";
+			$transaction->rollback();
+			return false;
+		}
+	}
+
+	// ...similar code for down()
+}
+~~~
+
+> Note: Not all DBMS support transactions. And some DB queries cannot be put
+> into a transaction. In this case, you will have to implement `up()` and
+> `down()`, instead. And for MySQL, some SQL statements may cause
+> [implicit commit](http://dev.mysql.com/doc/refman/5.1/en/implicit-commit.html).
+
+
+Applying Migrations
+-------------------
+
+To apply all available new migrations (i.e., make the local database up-to-date),
+run the following command:
+
+~~~
+yiic migrate
+~~~
+
+The command will show the list of all new migrations. If you confirm to apply
+the migrations, it will run the `up()` method in every new migration class, one
+after another, in the order of the timestamp value in the class name.
+
+After applying a migration, the migration tool will keep a record in a database
+table named `tbl_migration`. This allows the tool to identify which migrations
+have been applied and which are not. If the `tbl_migration` table does not exist,
+the tool will automatically create it in the database specified by the `db`
+application component.
+
+Sometimes, we may only want to apply one or a few new migrations. We can use the
+following command:
+
+~~~
+yiic migrate/up 3
+~~~
+
+This command will apply the 3 new migrations. Changing the value 3 will allow
+us to change the number of migrations to be applied.
+
+We can also migrate the database to a specific version with the following command:
+
+~~~
+yiic migrate/to 101129_185401
+~~~
+
+That is, we use the timestamp part of a migration name to specify the version
+that we want to migrate the database to. If there are multiple migrations between
+the last applied migration and the specified migration, all these migrations
+will be applied. If the specified migration has been applied before, then all
+migrations applied after it will be reverted (to be described in the next section).
+
+
+Reverting Migrations
+--------------------
+
+To revert the last one or several applied migrations, we can use the following
+command:
+
+~~~
+yiic migrate/down [step]
+~~~
+
+where the optional `step` parameter specifies how many migrations to be reverted
+back. It defaults to 1, meaning reverting back the last applied migration.
+
+As we described before, not all migrations can be reverted. Trying to revert
+such migrations will throw an exception and stop the whole reverting process.
+
+
+Redoing Migrations
+------------------
+
+Redoing migrations means first reverting and then applying the specified migrations.
+This can be done with the following command:
+
+~~~
+yiic migrate/redo [step]
+~~~
+
+where the optional `step` parameter specifies how many migrations to be redone.
+It defaults to 1, meaning redoing the last migration.
+
+
+Showing Migration Information
+-----------------------------
+
+Besides applying and reverting migrations, the migration tool can also display
+the migration history and the new migrations to be applied.
+
+~~~
+yiic migrate/history [limit]
+yiic migrate/new [limit]
+~~~
+
+where the optional parameter `limit` specifies the number of migrations to be
+displayed. If `limit` is not specified, all available migrations will be displayed.
+
+The first command shows the migrations that have been applied, while the second
+command shows the migrations that have not been applied.
+
+
+Modifying Migration History
+---------------------------
+
+Sometimes, we may want to modify the migration history to a specific migration
+version without actually applying or reverting the relevant migrations. This
+often happens when developing a new migration. We can use the following command
+to achieve this goal.
+
+~~~
+yiic migrate/mark 101129_185401
+~~~
+
+This command is very similar to `yiic migrate/to` command, except that it only
+modifies the migration history table to the specified version without applying
+or reverting the migrations.
+
+
+Customizing Migration Command
+-----------------------------
+
+There are several ways to customize the migration command.
+
+### Use Command Line Options
+
+The migration command comes with four options that can be specified in command
+line:
+
+* `interactive`: boolean, specifies whether to perform migrations in an
+  interactive mode. Defaults to true, meaning the user will be prompted when
+  performing a specific migration. You may set this to false should the
+  migrations be done in a background process.
+
+* `migrationPath`: string, specifies the directory storing all migration class
+  files. This must be specified in terms of a path alias, and the corresponding
+  directory must exist. If not specified, it will use the `migrations`
+  sub-directory under the application base path.
+
+* `migrationTable`: string, specifies the name of the database table for storing
+  migration history information. It defaults to `tbl_migration`. The table
+  structure is `version varchar(255) primary key, apply_time integer`.
+
+* `connectionID`: string, specifies the ID of the database application component.
+  Defaults to 'db'.
+
+* `templateFile`: string, specifies the path of the file to be served as the code
+  template for generating the migration classes. This must be specified in terms
+  of a path alias (e.g. `application.migrations.template`). If not set, an
+  internal template will be used. Inside the template, the token `{ClassName}`
+  will be replaced with the actual migration class name.
+
+To specify these options, execute the migrate command using the following format
+
+~~~
+yiic migrate/up --option1=value1 --option2=value2 ...
+~~~
+
+For example, if we want to migrate for a `forum` module whose migration files
+are located within the module's `migrations` directory, we can use the following
+command:
+
+~~~
+yiic migrate/up --migrationPath=ext.forum.migrations
+~~~
+
+
+### Configure Command Globally
+
+While command line options allow us to configure the migration command
+on-the-fly, sometimes we may want to configure the command once for all.
+For example, we may want to use a different table to store the migration history,
+or we may want to use a customized migration template. We can do so by modifying
+the console application's configuration file like the following,
+
+```php
+TBD
+```
+
+Now if we run the `migrate` command, the above configurations will take effect
+without requiring us to enter the command line options every time.

+Performance Tuning
+==================
+
+Application performance consists of two parts. First is the framework performance
+and the second is the application itself. Yii has a pretty low performance impact
+on your application out of the box and can be fine-tuned further for production
+environment. As for the application, we'll provide some of the best practices
+along with examples on how to apply them to Yii.
+
+Preparing framework for production
+----------------------------------
+
+### Disabling Debug Mode
+
+First thing you should do before deploying your application to production environment
+is to disable debug mode. A Yii application runs in debug mode if the constant
+`YII_DEBUG` is defined as `true` in `index.php` so to disable debug the following
+should be in your `index.php`:
+
+```php
+defined('YII_DEBUG') or define('YII_DEBUG', false);
+```
+
+Debug mode is very useful during development stage, but it would impact performance
+because some components cause extra burden in debug mode. For example, the message
+logger may record additional debug information for every message being logged.
+
+### Enabling PHP opcode cache
+
+Enabling the PHP opcode cache improves any PHP application performance and lowers
+memory usage significantly. Yii is no exception. It was tested with
+[APC PHP extension](http://php.net/manual/en/book.apc.php) that caches
+and optimizes PHP intermediate code and avoids the time spent in parsing PHP
+scripts for every incoming request.
+
+### Turning on ActiveRecord database schema caching
+
+If the application is using Active Record, we should turn on the schema caching
+to save the time of parsing database schema. This can be done by setting the
+`Connection::enableSchemaCache` property to be `true` via application configuration
+`protected/config/main.php`:
+
+```php
+return array(
+	// ...
+	'components' => array(
+		// ...
+		'db' => array(
+			'class' => 'yii\db\Connection',
+			'dsn' => 'mysql:host=localhost;dbname=mydatabase',
+			'username' => 'root',
+			'password' => '',
+			'enableSchemaCache' => true,
+
+			// Duration of schema cache.
+			// 'schemaCacheDuration' => 3600,
+
+			// Name of the cache component used. Default is 'cache'.
+			//'schemaCache' => 'cache',
+		),
+		'cache' => array(
+			'class' => 'yii\caching\FileCache',
+		),
+	),
+);
+```
+
+Note that `cache` application component should be configured.
+
+### Combining and Minimizing Assets
+
+TBD
+
+### Using better storage for sessions
+
+By default PHP uses files to handle sessions. It is OK for development and
+small projects but when it comes to handling concurrent requests it's better to
+switch to another storage such as database. You can do so by configuring your
+application via `protected/config/main.php`:
+
+```php
+return array(
+	// ...
+	'components' => array(
+		'session' => array(
+			'class' => 'yii\web\DbSession',
+
+			// Set the following if want to use DB component other than
+			// default 'db'.
+			// 'db' => 'mydb',
+
+			// To override default session table set the following
+			// 'sessionTable' => 'my_session',
+		),
+	),
+);
+```
+
+You can use `CacheSession` to store sessions using cache. Note that some
+cache storages such as memcached has no guaranteee that session data will not
+be lost leading to unexpected logouts.
+
+Improving application
+---------------------
+
+### Using Serverside Caching Techniques
+
+As described in the Caching section, Yii provides several caching solutions that
+may improve the performance of a Web application significantly. If the generation
+of some data takes long time, we can use the data caching approach to reduce the
+data generation frequency; If a portion of page remains relatively static, we
+can use the fragment caching approach to reduce its rendering frequency;
+If a whole page remains relative static, we can use the page caching approach to
+save the rendering cost for the whole page.
+
+
+### Leveraging HTTP to save procesing time and bandwidth
+
+TBD
+
+### Database Optimization
+
+Fetching data from database is often the main performance bottleneck in
+a Web application. Although using caching may alleviate the performance hit,
+it does not fully solve the problem. When the database contains enormous data
+and the cached data is invalid, fetching the latest data could be prohibitively
+expensive without proper database and query design.
+
+Design index wisely in a database. Indexing can make SELECT queries much faster,
+but it may slow down INSERT, UPDATE or DELETE queries.
+
+For complex queries, it is recommended to create a database view for it instead
+of issuing the queries inside the PHP code and asking DBMS to parse them repetitively.
+
+Do not overuse Active Record. Although Active Record is good at modelling data
+in an OOP fashion, it actually degrades performance due to the fact that it needs
+to create one or several objects to represent each row of query result. For data
+intensive applications, using DAO or database APIs at lower level could be
+a better choice.
+
+Last but not least, use LIMIT in your SELECT queries. This avoids fetching
+overwhelming data from database and exhausting the memory allocated to PHP.
+
+### Using asArray
+
+A good way to save memory and processing time on read-only pages is to use
+ActiveRecord's `asArray` method.
+
+```php
+class PostController extends Controller
+{
+	public function actionIndex()
+	{
+		$posts = Post::find()->orderBy('id DESC')->limit(100)->asArray()->all();
+		echo $this->render('index', array(
+			'posts' => $posts,
+		));
+	}
+}
+```
+
+In the view you should access fields of each invidual record from `$posts` as array:
+
+```php
+foreach($posts as $post) {
+	echo $post['title']."<br>";
+}
+```
+
+Note that you can use array notation even if `asArray` wasn't specified and you're
+working with AR objects.
+
+### Processing data in background
+
+In order to respond to user requests faster you can process heavy parts of the
+request later if there's no need for immediate response.
