What is Docker?

Docker is an open platform for building, shipping and running distributed applications. It gives programmers, development teams and operations engineers the common toolbox they need to take advantage of the distributed and networked nature of modern applications.

Virtual Machines vs Docker

Containers have similar resource isolation and allocation benefits as virtual machines but a different architectural approach allows them to be much more portable and efficient.

Virtual Machines	Containers
Each virtual machine includes the application, the necessary binaries and libraries and an entire guest operating system – all of which may be tens of GBs in size.	Containers include the application and all of its dependencies, but share the kernel with other containers. They run as an isolated process in userspace on the host operating system. They’re also not tied to any specific infrastructure – Docker containers run on any computer, on any infrastructure and in any cloud.

For example, if you have to use DHCP in your home network but if your office use Static IP, you have to change your network adapter settings every times.

You can use ‘Wireless Configuration Changer‘ application by ZemnaSoft to change network adapter settings automatically.

This application saves each network adapter settings as profile. So, if you set network adapter settings at first time and save it, application will apply saved profile to network adapter when the wireless has connected.

Key Features

• Wireless configuration profile management
• Automatically changes network settings by connection
• Automatically starts at windows startup

This means, SlimCleaner uses aggregated-cloud feedback to recommend optimal settings for programs, start-ups and services.

SlimCleaner uses what’s called “authoritative ranking” to ensure that the ratings for your programs are accurate and that they reflect what people really think. It works by weighing the ratings of each contributor against their previous levels of accuracy and against the ratings of high-ranking users.

My Sony Vaio laptop also takes more than 1 minute to showing login screen. I fully stressed because of this, but can fix this problem by this tip.

You can read this great article to fix it.

Part1 – System Analysis & Database Design

1. System Analysis

1.1. Requirements

• User can register using signup feature. User can login using user credentials.
• If user forget password, user can reset password using registered email.
• User can login using social account like Google, Facebook and Twitter.

1.2. Big Flow

The big flow of this feature likes following picture.

When user connect to website, user can login using basic login system and also social login. Each login feature have different business logic.

Basic Login

Process is like as traditional one. User register using username, email, password, display name, etc. After register, user can login using username(or email) and password. System also can give a feature to reset password for user who forget password.

Social Login

User also can login using their social account like Google, Facebook and Twitter. Social login has three steps to process. Authorize app by social webpage, verify user in user database and connect social account with user database.

2. Database Design

Let’s make a database for user management.

2.1. Entity Relationship Diagram

There are 3 tables to manage user. I divided table by feature group.

‘user’ Table

This is the main table of user. All users have one record in this table. When user login using social login feature, system searches user table to check existence and add record if doesn’t exist.

CREATE TABLE `user` (
  `id` bigint(20) NOT NULL AUTO_INCREMENT,
  `username` varchar(16) NOT NULL,
  `email` varchar(50) NOT NULL,
  `password` varchar(128) DEFAULT NULL,
  `display_name` varchar(50) NOT NULL,
  `created` datetime NOT NULL,
  `user_group` int(11) NOT NULL,
  PRIMARY KEY (`id`),
  UNIQUE KEY `email` (`email`),
  UNIQUE KEY `username` (`username`)
) ENGINE=InnoDB  DEFAULT CHARSET=utf8;

‘user_password_reset’ Table

This table is used for reset password. I divided this table from user table because of frequency. If user want to reset password, system add a new record to ‘user_password_reset’ table with temporary reset verification key and verification expiration date. This key will be sent to user via email. User can click password reset link from email and set a new password. After complete to set a new password, record in this table will be deleted automatically. User also can’t be set a new password if link is already expired.

CREATE TABLE `user_password_reset` (
  `user_id` bigint(20) NOT NULL,
  `reset_key` varchar(32) NOT NULL,
  `reset_key_expired` datetime NOT NULL,
  PRIMARY KEY (`user_id`),
  UNIQUE KEY `reset_key` (`reset_key`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

‘user_provider’ Table

This table is for manage social account. Many people have multiple social account. To protect duplication of user creation, social login information will be saved to ‘user_provider’ table and connect with main ‘user’ table.

CREATE TABLE `user_provider` (
  `id` bigint(20) NOT NULL AUTO_INCREMENT,
  `user_id` bigint(20) NOT NULL,
  `provider` varchar(20) NOT NULL,
  `provider_uid` varchar(255) NOT NULL,
  PRIMARY KEY (`id`),
  KEY `user_id` (`user_id`)
) ENGINE=InnoDB  DEFAULT CHARSET=utf8;

3. Conclusion

In this article, we made a business flow of user management feature and also made a database.
