Login System Using NodeJS & MySQL Database

In this video we will build a NodeJS & MySQL Database Login System. For this tutorial we’ll be doing something a little different, instead of developing applications with PHP we’ll be creating a login system with Node.js, and MySQL.

System Databases in SQL Server

Introduction

In SSMS, we many of may noticed System Databases under the Database Folder. But how many of us knows its purpose?. In this article lets discuss about the System Databases in SQL Server.

System Database

Fig. 1 System Databases

There are five system databases, these databases are created while installing SQL Server.

  • Master
  • Model
  • MSDB
  • Tempdb
  • Resource
Master
  • This database contains all the System level Information in SQL Server. The Information in form of Meta data.
  • Because of this master database, we are able to access the SQL Server (On premise SQL Server)
Model
  • This database is used as a template for new databases.
  • Whenever a new database is created, initially a copy of model database is what created as new database.
MSDB
  • This database is where a service called SQL Server Agent stores its data.
  • SQL server Agent is in charge of automation, which includes entities such as jobs, schedules, and alerts.
TempDB
  • The Tempdb is where SQL Server stores temporary data such as work tables, sort space, row versioning information and etc.
  • User can create their own version of temporary tables and those are stored in Tempdb.
  • But this database is destroyed and recreated every time when we restart the instance of SQL Server.
Resource
  • The resource database is a hidden, read only database that holds the definitions of all system objects.
  • When we query system object in a database, they appear to reside in the sys schema of the local database, but in actually their definitions reside in the resource db.

Best MySQL DigitalOcean Performance – ScaleGrid vs. DigitalOcean Managed Databases

HTML to Markdown

MySQL is the all-time number one open source database in the world, and a staple in RDBMS space. DigitalOcean is quickly building its reputation as the developers cloud by providing an affordable, flexible and easy to use cloud platform for developers to work with. MySQL on DigitalOcean is a natural fit, but what’s the best way to deploy your cloud database? In this post, we are going to compare the top two providers, DigitalOcean Managed Databases for MySQL vs. ScaleGrid MySQL hosting on DigitalOcean.

At a glance – TLDR
ScaleGrid Blog - At a glance overview - 1st pointCompare Throughput
ScaleGrid averages almost 40% higher throughput over DigitalOcean for MySQL, with up to 46% higher throughput in write-intensive workloads. Read now

ScaleGrid Blog - At a glance overview - 2nd pointCompare Latency
On average, ScaleGrid achieves almost 30% lower latency over DigitalOcean for the same deployment configurations. Read now

ScaleGrid Blog - At a glance overview - 3rd pointCompare Pricing
ScaleGrid provides 30% more storage on average vs. DigitalOcean for MySQL at the same affordable price. Read now

MySQL DigitalOcean Performance Benchmark
In this benchmark, we compare equivalent plan sizes between ScaleGrid MySQL on DigitalOcean and DigitalOcean Managed Databases for MySQL. We are going to use a common, popular plan size using the below configurations for this performance benchmark:

Comparison Overview
ScaleGridDigitalOceanInstance TypeMedium: 4 vCPUsMedium: 4 vCPUsMySQL Version8.0.208.0.20RAM8GB8GBSSD140GB115GBDeployment TypeStandaloneStandaloneRegionSF03SF03SupportIncludedBusiness-level support included with account sizes over $500/monthMonthly Price$120$120

As you can see above, ScaleGrid and DigitalOcean offer the same plan configurations across this plan size, apart from SSD where ScaleGrid provides over 20% more storage for the same price.

To ensure the most accurate results in our performance tests, we run the benchmark four times for each comparison to find the average performance across throughput and latency over read-intensive workloads, balanced workloads, and write-intensive workloads.

Throughput
In this benchmark, we measure MySQL throughput in terms of queries per second (QPS) to measure our query efficiency. To quickly summarize the results, we display read-intensive, write-intensive and balanced workload averages below for 150 threads for ScaleGrid vs. DigitalOcean MySQL:

Create Password Protected Webpage Using PHP, HTML And CSS

In this tutorial we will show you how to create password protected webpage using PHP, HTML and CSS.
In this user have to write correct password to see the webpage content without password user will not be able to see the webpage content.

To Create Password Protected webpage It Takes Only Two Steps:-

  1. Make a PHP file and define markup
  2. Make a CSS file and define styling

Step 1. Make a PHP file and define markup

We make a PHP file and save it with a name password.php

<?php
session_start();

if(isset($_POST['submit_pass']) && $_POST['pass'])
{
 $pass=$_POST['pass'];
 if($pass=="123")
 {
  $_SESSION['password']=$pass;
 }
 else
 {
  $error="Incorrect Pssword";
 }
}

if(isset($_POST['page_logout']))
{
 unset($_SESSION['password']);
}
?>

<html>
<head>
<link rel="stylesheet" type="text/css" href="password_style.css">
</head>
<body>
<div id="wrapper">

<?php
if($_SESSION['password']=="123")
{
 ?>
 <h1>Create Password Protected Webpage Using PHP, HTML And CSS</h1>
 <form method="post" action="" id="logout_form">
  <input type="submit" name="page_logout" value="LOGOUT">
 </form>
 <?php
}
else
{
 ?>
 <form method="post" action="" id="login_form">
  <h1>LOGIN TO PROCEED</h1>
  <input type="password" name="pass" placeholder="*******">
  <input type="submit" name="submit_pass" value="DO SUBMIT">
  <p>"Password : 123"</p>
  <p><font style="color:red;"><?php echo $error;?></font></p>
 </form>
 <?php	
}
?>

</div>
</body>
</html>

In this step we first check if user logged in or not by checking session variable if the user is not logged in we display login form and if user is logged in we display webpage content with logout button.

We use two isset() condition to do login or logout.In first condition we simply get the password and check if the password is '123' if yes we put the password in session variable and then display the webpage.

In second condition we simply unset the session variable which stores password value. You may also like simple http authentication using PHP .

Step 2. Make a CSS file and define styling

We make a CSS file and save it with a name password_style.css

body
{
 margin:0 auto;
 padding:0px;
 text-align:center;
 width:100%;
 font-family: "Myriad Pro","Helvetica Neue",Helvetica,Arial,Sans-Serif;
 background-color:#8A4B08;
}
#wrapper
{
 margin:0 auto;
 padding:0px;
 text-align:center;
 width:995px;
}
#wrapper h1
{
 margin-top:50px;
 font-size:45px;
 color:white;
}
#wrapper p
{
 font-size:16px;
}
#logout_form input[type="submit"]
{
 width:250px;
 margin-top:10px;
 height:40px;
 font-size:16px;
 background:none;
 border:2px solid white;
 color:white;
}
#login_form
{
 margin-top:200px;
 background-color:white;
 width:350px;
 margin-left:310px;
 padding:20px;
 box-sizing:border-box;
 box-shadow:0px 0px 10px 0px #3B240B;
}
#login_form h1
{
 margin:0px;
 font-size:25px;
 color:#8A4B08;
}
#login_form input[type="password"]
{
 width:250px;
 margin-top:10px;
 height:40px;
 padding-left:10px;
 font-size:16px;
}
#login_form input[type="submit"]
{
 width:250px;
 margin-top:10px;
 height:40px;
 font-size:16px;
 background-color:#8A4B08;
 border:none;
 box-shadow:0px 4px 0px 0px #61380B;
 color:white;
 border-radius:3px;
}
#login_form p
{
 margin:0px;
 margin-top:15px;
