While you don't need to learn all of these to become a database administrator, I have mentioned them to make you more competent and complete database administrator.

In order to start with you can focus on these 4 things first:

1. Learn SQL Language

The SQL language is the language that is used in every tech job related to the data like machine learning engineer, web developer, data analyzer, and database administrator is one of them.

1.1. The Complete SQL Bootcamp: Go from Zero to Hero

This is one of the best Udemy course to start learning Database and SQL. This course will teach you the basics of the SQL language and database design without any prior knowledge required in the database or SQL language.

You will start with an introduction to the relational database and its design and then use the SQL language queries to add data to the database, retrieve the data, and modify it.

2. Learn Linux System

Linux operating system is dominating the cloud servers being the most used system compared to windows, and that's because it is free to use, so you don't need to obtain a license to use it and more secure than other systems.

Not only that, but there are a lot of other benefits of using Linux in your servers, such as the vast community that will help you fix any problem that happens, and you can customize it the way you want. I will suggest one course that will help you learn this system:

2.1. Learning Linux for LFCA

This is a course intended to teach beginners how to use the Linux operating system and become proficient in it. You will start by learning the Linux fundamentals, such as working with files and exploring different Linux distributions. Then learn to manage the Linux systems, the security in Linux, and Linux in the cloud.

3. Learn Oracle Database

Oracle database is the most used database software among companies to store their user's data in the cloud. They are s popular and used for online transaction processing, data warehousing, and more.

One of the reasons companies use this database software is its flexibility standards and scale to be in the right size of your business needs, the cost of running this software, and its security. I will suggest a course that will help you run this database software:

3.1. Oracle SQL Databases:

This is a course intended to help beginners learn the skills of running oracle database software and run SQL queries on it. You will start by understanding the oracle database and building the database structure.

Then you will learn how to navigate the oracle database software using the interface and command line. Next, learn how to use the SQL language inside the oracle database as a beginner until you are an intermediate user of this language.

4. Learn PostgreSQL Database

There is a lot of database software. Not all companies use the Oracle database because although it is good, sometimes you need another alternative that meets your business's needs. One of the best alternatives to the Oracle database is PostgreSQL.

PostgreSQL is an open-source database which means you will use it for free of cost and without obtaining any license since the volunteer community developed it.

This database uses a lot in a data warehouse that supports business intelligence activities such as analyzing data and more.

Also, since PostgreSQL is open source, it is very secure since the developer can see the code and find the vulnerabilities. I will recommend one of the best courses to learn PostgreSQL created by Michigan University:

4.1. PostgreSQL for Everybody

This is one of the best courses to learn this database software and the SQL language. You will start by understanding the database design and how to run SQL commands on the database to add, remove, update data.

Next, you will learn more about the SQL commands and how to spidering the web data, store them as a JSON file in the PostgreSQL database, and learn about the NoSQL database.

By the way, If you are planning to join multiple courses and specializations on Coursera, then consider taking a Coursera Plus subscription which provides you unlimited access to their most popular courses, specialization, professional certificate, and guided projects.

It costs around $59/ per month but is worth it because you get access to more than 7000+ courses and projects, and you can also get access to unlimited professional certificates like Google's Data analytics Certification, Microsoft Cyber Security Certification and Meta's Frontend Development Certificate.
