PostgreSQL Database Administration (DBA) for Beginners from Udemy

PostgreSQL is commonly known as Postgres and it is also open source database.

PostgreSQL is a powerful, open source object-relational database system.

A database administrator’s (DBA) primary job is to ensure that data is available, protected from loss and corruption, and easily accessible as needed.

The PostgreSQL administration covers some of the most important PostgreSQL database server administration activities.

Some of the Key Responsibilities of a Database Administrator includes:

Database Management
Database Backup and restore
Tablespace management
Role Management
Managing users
Securing database via proper role management

A DBA ( Database administrator) has to perform several responsibilities to ensure the smooth running of the SQL sever database.

In this course, we will go over the basics of the PostgreSQL. We will cover topics ranging from installations, to writing basic queries and retrieving data from tables. We will also explore the logic of joining tables to retrieve data and much more.

The course also covers the basics of creating tables, storing data with data types, and working with expressions, operators, and strings.

Topics also includes:

Installing PostgreSQL
Loading sample database
Creating database and tables
Performing CRUD operations
Joining Tables
Using aggregate and analytic functions
Creating views and triggers

This is a practical hands-on course that will equip you with the skills and confidence to work with PostgreSQL .

Beginner's guide to postgresql basics

According to students, this course provides a solid foundation for beginners looking to learn PostgreSQL. Many found the explanations of basic SQL commands, joins, and aggregate functions to be clear and helpful. The hands-on examples were frequently cited as beneficial for practical understanding. However, some learners noted that despite the title, the course focuses more on querying and fundamental concepts rather than in-depth database administration tasks implied by the title, which could potentially set slightly different expectations for those specifically seeking advanced DBA knowledge. Overall, it serves as a recommended starting point for newcomers.

Helpful coding practice included

"I really appreciated the hands-on demos and coding exercises throughout the modules."

"Being able to code along with the instructor solidified my understanding of the concepts."

"The practical approach helped me learn faster than just theory alone."

"The examples provided were relevant and easy to replicate on my own system."

Covers essential querying skills

"The sections on basic SQL, joins, and functions were exactly what I needed to start querying."

"Learned how to write the basic queries, perform CRUD operations, and effectively use joins."

"The explanations of aggregate functions and views were very useful for data analysis."

"Good coverage of filtering, sorting, and grouping data which are core SQL skills."

Great starting point for newcomers

"This course is perfect for someone just starting out with databases like PostgreSQL."

"It gave me a really solid base understanding of the fundamentals I needed to get started."

"Explains the core concepts clearly for absolute beginners, making it very accessible."

"I had no prior database experience and found this course easy to follow and learn from."

More query skills than admin tasks

"Despite the title, this felt more like a SQL querying course than a true DBA course."

"Wish it covered more advanced administration topics like monitoring or performance tuning strategies."

"The 'DBA' part of the title might be slightly misleading regarding the depth of administrative content."

"It's good for basic setup and querying, but don't expect a deep dive into daily administrative duties."
