What is MySQL – Manual for beginners

Mysql:

Anyone who wants to delve into the computer world must keep abreast of a number of technological terminology in this area. Even more when you start using a website hosting. Today you will learn what is MySQL, how this type of database works and what the most important advantages are.

What is MySQL?

MySQL is an open source relational database management system (RBDM & # 39; s) with operation based on a client-server model.

the RBDMS is a software (program) or service that is used to create and manage databases based on a two-way relationship model.

MySQL started in 1994 with the development of a program by the Swedish company MySQL AB. The American company Sun Microsystems bought MySQL AB in 2008 and owned the technology.

In 2010, Sun Micrososystems was taken over by Oracle, which still owns MySQL.

Below you can read some of the most important terminologies that relate to MySQL.

Database

A database is nothing more than a large group of structured data. For comparison, consider taking a selfie: your photo is a given and the photo gallery of your smartphone is the database.

A database is where data is stored and organized. And the term relational means that this stored data is organized in data sets and organized directly in tables.

Each of these tables has a different relationship with the data in it. And if the software is not compatible with the relational data model, it is called DBM & # 39; s.

Open source

Being open source means that the system is free to use. And you can even adjust it to your liking. You can still learn and improve source code to adapt to your user needs.

However, you must pay attention to the GPL (GNU General Public License), which determines the types of changes and adjustments that may be made to a system. A commercially licensed version is available if you need more flexibility and advanced support.

Client-server model

The model Client Server is provided by two sides of a comparison. The computers that install and run RBDM software are the customers. When they access data, they connect to a server RBDM.

MySQL is just one of many existing RBDMS software options. RBDMS and MySQl are often thought together because of the immense popularity of MySQL.

As an example of this opportunity, networks such as Facebook Twitter, YouTube and Google use MySQL to store and store data from billions of users worldwide.

Other than that, although it is made with a certain usage restriction, MySQL is currently compatible with almost all computer platforms. This is the case with Windows, Linux (and their distributions) and MacOS.

But what about SQL?

First of all, MySQL and SQL are not the same. While the first is an RBDM database, the second is the language (Structured query language) that use databases to establish client-server communication.

If you come across other SQL-related terminologies, such as PostegreSL and Microsoft SQL, keep in mind that these are probably other tags that use the well-known SQL syntax.

RBDM database software is usually developed in other programming languages, but always uses SQL as the primary language to communicate with the database. MySQL is based on the C and C ++ languages.

SQL was developed in the early 1970s by computer scientist Ted Codd. Based on a relational model from IBM, language scripting became so popular in 1974 that it replaced other outdated languages ​​such as ISAM and VISAM.

SQL works by telling the MySQL server exactly what to do with the stored data. It is as if it acts as your password to log in to WordPress, which you enter in the appropriate field and access the CMS control panel.

In this case, SQL issues actions that the MySQL server can perform. Some of the operations can be:

  • Search data: Asks for information that is specific to the current database.
  • Data processing: It adds, removes, modifies and organizes, among other edits of data, their values ​​and visuals.
  • Data identity: This separates the data type (for example, changing numeric data to whole numbers). This also allows you to create a relationship for each database table.
  • Data Access Control: Provides security techniques to protect data in a database. The user determines who can view or use information in the system.

How does MySQL work?

You already know that MySQL works from a relationship Client Server. This model works in such a way that every machine or device (client) connects to the server via a specific internet network.

As for the side of it customer is to execute requests through a graphical user interface (GUI) from which the server will display the requested content.

This is because both parties understand what is being asked and what should be sent as an answer.

In general, the summary of this communication is:

  1. MySQL creates a database for storing and manipulating the data, whereby the functionality is defined for each created table.
  2. Customer makes requests by entering SQL instructions in MySQL.
  3. The server responds with the requested information, which is then delivered to the client.

The lighter and friendlier the graphical user interface (GUI), the faster and easier it becomes for the user to use and modify database data.

A part of Most used MySQL GUI & # 39; s are MySQL Workbench, DBVisualizer, SequelPro and Navicat DB Admin Tool. Some of them are free, others are paid. Meanwhile, some are multi-platform and others only work with a specific operating system.

Every user (and customer) must choose the most suitable GUI for his company based on his experience with database management. One of the most common options for people who work with the WordPress is the phpMyAdmin.

Advantages of using MySQL

According to DB Engines (image above), the MySQL It is not the only (R) DBMS on the market, but it is also one of the most important and widely used oracle.

This includes parameters such as the number of entries in search engine search results, professional profiles of LinkedIN and the amount of discussion in online communities and forums.

But you might wonder why MySQL is so popular. In short, this is thanks to 4 of the most important functions. They are listed below.

High performance

A large amount of server clustering keeps the performance of MySQL high. Regardless of whether you need to store large amounts of e-commerce data or do business intelligence activities, MySQL helps you with its optimized speed.

Flexible and easy to use

You can adjust the source code of MySQL to your needs. And you don’t have to pay anything to have that kind of freedom. This includes specific options for upgrading to the full commercial version. The installation of everything is relatively quiet and does not take half an hour.

safety

Data security is what you must prioritize in every project. MySQL takes this to a new level with its Privileged Access System and User Account Management. It is the user who determines the authentication of accesses, logins and passwords, all encrypted.

An industry standard

Large companies have been using MySQL for many years. This means that it is a very reliable platform and that there is a very abundant source of resources for experienced developers. Those who already use the tool can expect a major evolution with it. And anyone who needs a freelance service will easily find experienced developers.
