By Using React Commands with the mention technologies (DOM, Bootstrap, Axios, Hooks) to create React_App Applications.

 

To create a "Blog_App "using React with the mentioned technologies (DOM, Bootstrap, Axios, Hooks), you can follow these steps:

Step 1: Set up the React project

Make sure you have Node.js installed on your machine.

Open your terminal and navigate to the desired directory where you want to create your project.

Run the following command to create a new React project:

Step 2: Install necessary dependencies

         

Step 3: Build the basic structure of the blog

Open the src folder and remove all the files except index.js and App.js.

Create a new folder called components inside the src folder.

Inside the components folder, create a new file called Blog.js. This will be the main component for your blog.

Step 4: Implement the blog functionality

Open the Blog.js file and import the necessary dependencies:

import React, { useState, useEffect } from 'react';

import axios from 'axios';

import 'bootstrap/dist/css/bootstrap.min.css';

Create a functional component called Blog:

  const Blog = () => {

  const [posts, setPosts] = useState([]);

  useEffect(() => {

    // Fetch blog posts from an API endpoint using Axios

    axios.get('https://api.example.com/posts')

      .then(response => {

        setPosts(response.data);

      })

      .catch(error => {

        console.error(error);

      });

  }, []);

  return (

    <div className="container">

      <h1>My Blog</h1>

      {posts.map(post => (

        <div key={post.id}>

          <h2>{post.title}</h2>

          <p>{post.body}</p>

        </div>

      ))}

    </div>

  );

};

export default Blog;

Update the App.js file to render the Blog component:

import React from 'react';

import Blog from './components/Blog';

function App() {

  return (

    <div className="App">

      <Blog />

    </div>

  );

}

export default App;

Step 5: Start the development server

Save all the files, and in the terminal, run the following command from the root of your project:

React will start the development server, and you should see your blog running in your browser at http://localhost:3000.

NOTE: You have created a basic blog using React, Axios for fetching data, Bootstrap for styling, and React Hooks for managing state. You can further customize and enhance your blog by adding features like creating new posts, implementing authentication, and more.

To getting Backup and Restore Entire Database By using MySQL(Incremental Backup)

The SQL query "SHOW FULL TABLES WHERE Table_type != "VIEW"" is used to retrieve a list of all the tables in a database where the table type is not a "view".

In a relational database management system (RDBMS), a view is a virtual table that does not physically exist in the database but is created by a query. The view provides a customized or filtered view of one or more tables, which can be useful for simplifying complex queries or controlling access to sensitive data.

The query "SHOW FULL TABLES" returns a list of all tables in the database along with their types, and the "WHERE" clause is used to filter the results based on the table type. In this case, we are excluding views from the results by specifying "Table_type != 'VIEW'".

By executing this query, you will get a list of all the non-virtual tables in the database. These tables are typically created using the CREATE TABLE statement, and their data is physically stored in the database.

SQL query "SHOW FULL TABLES WHERE Table_type != 'VIEW'"

SHOW FULL TABLES: This is a SQL command that is used to display a list of all tables in a database. The "FULL" keyword in this command specifies that additional information about each table, such as the table type and the storage engine, should also be displayed.

WHERE Table_type != 'VIEW': This is a clause that is used to filter the list of tables returned by the SHOW FULL TABLES command. In this case, the clause specifies that only tables whose Table_type is not equal to 'VIEW' should be included in the results. This means that any views in the database will be excluded from the list.

Overall, this SQL query will display a list of all tables in the database that are not views, along with additional information about each table.

Data Backup & Restore For MySQL (Command-Line)

MySQL is a popular open-source relational database management system. It is important to create regular backups of MySQL databases to protect against data loss due to hardware failures, software bugs, or other issues. In this answer, I will explain how to backup and restore a MySQL database using the command-line interface.

Backup using mysqldump:

The mysqldump command is used to create backups of MySQL databases. Here are the steps to backup a MySQL database using mysqldump:Open the command-line interface (e.g., Terminal on Mac or Linux, Command Prompt on Windows).Type the following command to create a backup of the database:

                       "mysqldump -u username -p database_name > backup_file.sql".

Replace "username" with your MySQL username, "database_name" with the name of the database you want to backup, and "backup_file.sql" with the name of the file you want to save the backup to.Enter your MySQL password when prompted.

The above command creates a backup file in SQL format that contains all the data and structure of the specified database.

Restore using mysql:

To restore a MySQL database from a backup file, use the mysql command. Here are the steps to restore a MySQL database using the mysql command:Open the command-line interface.Type the following command to restore the database:

                  "mysql -u username -p database_name < backup_file.sql".

Replace "username" with your MySQL username, "database_name" with the name of the database you want to restore, and "backup_file.sql" with the name of the backup file.Enter your MySQL password when prompted.The above command restores the database from the backup file.

               

 Following some steps to choose specific path you store entire data with specific       database with backup and restore: 

Note : If the database already exists, the above command will overwrite the existing data with the data  from the backup file. If you want to create a new database from the backup file, you can use the  following command:

                                     "mysql -u username -p < backup_file.sql".

This command will create a new database with the same name as the database in the backup file, and import the data and structure from the backup file.

In conclusion, using the mysqldump and mysql commands is a simple and effective way to backup and restore MySQL databases. By regularly creating backups and storing them in a safe place, you can protect your valuable data from potential loss or corruption.
