How to Learn MySQL
Have you ever wondered what happens to data that is collected by a website? Every time the front end of a website collects data, it needs a place to store it. This place is called a database.
One type of database that you can use is a relational database, where categories of data can relate to, or interact with, each other. MySQL is a relational database and SQL is the language you can use to access, update, and manipulate the data within MySQL.
What Is MySQL?
MySQL is a relational database management system (RDBMS) that you can use with SQL (Structured Query Language). MySQL has many applications, including storing data, powering social media sites, and helping facilitate e-commerce services. MySQL is a combination of “My”, which is the co-founder’s daughter’s name, and SQL.
MySQL is an important skill to learn for web development, whether you want to focus on front end, back end, or full stack development.
What Is MySQL Used For?
Here are the main ways that MySQL is used:
- Powering social media sites. MySQL is used for websites like Facebook and Twitter. By using MySQL, these social media sites are able to store and retrieve information about users and then make that information available to users upon their request. That means that you’re able to easily see content that you’ve posted to these social media sites, such as text updates and photos.
- Storing data like blog articles. MySQL is used for websites like WordPress. If you have ever started a blog on WordPress, you know that it is capable of storing many blog posts written by different users, along with other data like photos. To store all of this content as data, WordPress needs a database and tools for managing that database. That is where MySQL comes in. Users can create, store, and retrieve their blog posts.
- Helping e-commerce flourish. The “shopping cart” feature is a common element of most online stores. It stores the items that you have selected and makes sure that all the articles are there when you are ready to check out. Those items are stored in a database like MySQL.
- Querying and manipulating data. With a data manipulation language (DML), you can insert, delete, and modify data in a database. SQL is a DML that can retrieve and manipulate data in a relational database like MySQL . For example, you can use SQL’s “Select” command to retrieve data from the MySQL database by using a command line interface or a scripting language (such as PHP, Perl , or Python ).
MySQL is a valuable skill to learn if you want to be a full stack or back end software engineer, or if you want to be a front end engineer. This is because learning MySQL will help you understand how the entire application that you’re running works.
That said, what is the best way to get started with learning MySQL?
Why Should I Learn MySQL?
You should learn MySQL if you want to get into software engineering, as pretty much any website is going to store user data so it can be retrieved for later use. Companies such as WordPress, Facebook, Twitter, and YouTube all use MySQL to power their databases that store user data.
MySQL is used for data analysis. Data analysis is crucial in many areas, from business to research and journalism. In a business context, you can use data to make decisions about how resources should be allocated and where growth has occurred. Pairing MySQL with SQL can help you dig into the data needed to make these decisions. If you perform research in an academic or journalistic setting, data analysis can help you identify patterns that can inform the content you produce.
MySQL and SQL are also valuable in data science . You can load data into a MySQL database, clean the data (remove inaccuracies), and then use SQL queries to lift insights from your data.
Here are some top reasons why you should learn MySQL:
MySQL is popular
MySQL is one of the most popular relational database management systems. It’s free and open source, runs on common operating systems like Windows, Linux, and MacOS, and is relevant for many data storage and analysis needs. According to the Stack Overflow 2020 Developer Survey , MySQL ranks as the most popular database, with 55.6% of all respondents choosing MySQL over other database options like PostgreSQL and Microsoft SQL Server.
MySQL has a strong community
With so many websites relying on MySQL for their database needs, you can bet that there are many people who are discussing ways to improve their MySQL skills. You can go to sites like StackOverflow to ask questions about MySQL and share what you are learning with the wider community. There are MySQL events, a Slack channel, and user groups. You can learn more about the MySQL community on the MySQL Community Resources page.
MySQL skills are in demand
As of this writing, there are over 19,000 job postings on LinkedIn that mention MySQL for jobs in the United States. On Glassdoor, there are over 13,000 . Based on these job descriptions, the type of roles where knowledge of MySQL is needed or helpful include positions like web developer, Python developer, and digital copywriter. Knowing how to manage a database can be useful in a variety of contexts, whether you are a full-time developer or have some other role.
To get some more perspective on the role of MySQL in today’s job market, let’s look at some salary numbers. According to Glassdoor , the average annual base pay of a MySQL database administrator is $76,526. Salary.com lists the hourly wage for a MySQL database engineer as being between $59 and $82 ($122,720-$170,560 a year).
How Long Does It Take to Learn MySQL?
If you already have some programming experience, learning the basics of MySQL could take you as little as two to three weeks. Keep in mind that really understanding how to use MySQL involves knowing how to use it with SQL and how to use a code editor like MySQL Workbench.
To fully comprehend the role that MySQL plays in websites, you’ll probably need some background in web development. In other words, before you start learning MySQL, it is good to have even just a basic understanding of HTML, CSS, and a scripting language such as Python, PHP, or Perl.
How to Learn MySQL: Step-by-Step
There’s no single right or wrong way to learn MySQL. Some people prefer to watch a lot of YouTube videos, go through tutorials and courses, and read the MySQL documentation before installing and using MySQL. Others like to do just a little research, install MySQL, and start actually using it while reaching out to the MySQL community and resources as needed. Wherever you are in your MySQL learning journey, following these general big-picture steps will help you.
Here is a basic framework for getting started with MySQL:
- Decide why you want to learn MySQL. What is your main motivation for learning MySQL? Do you want to get a job as a MySQL developer? Perhaps you want to use MySQL in a different role where databases play a part in the work you do, such as marketing.
- Learn how to install the necessary components. You’ll need to install MySQL and MySQL Workbench in order to get started.
- Practice your skills. Once you understand the basic setup of MySQL, you’ll need to practice your skills consistently to solidify your knowledge.
- Tap into MySQL resources like courses, books, and the MySQL community. As you’re experimenting on your own, you should also check out courses, books, and other resources (like the ones we’ve listed below) to continue expanding your skills.
- Teach others what you’ve learned. One of the best ways to find out what you actually know and don’t know in any area of expertise is to teach it to others. Explain what you’ve learned to a co-worker or friend who is interested in database management, or answer other developers’ questions on sites like StackOverflow .
