New Course Coming Soon:

Get Really Good at Git

The main properties of a database and of a DBMS.

A database is a collection of information carefully organized into a system.

The technology that in a computer system lets us organize data and represent the information that’s essential for an information system is called Database Management System.

A DBMS is a software that encapsulates the data of a database, and provides us a centralized way to store it, retrieve it, edit it, persist it, and much more.

Let’s define some of the main properties of a DBMS:

There are a lot of different DBMS on the market. Some similar to each other, some vastly different.

Relational DBMS, built on top of the relational model, are some of the most common ones you can use in the real world.

I’ll soon talk in details about 3 popular Open Source Relational Database Management Systems: PostgreSQL, MySQL and SQLite.

Are you intimidated by Git? Can’t figure out merge vs rebase? Are you afraid of screwing up something any time you have to do something in Git? Do you rely on ChatGPT or random people’s answer on StackOverflow to fix your problems? Your coworkers are tired of explaining Git to you all the time? Git is something we all need to use, but few of us really master it. I created this course to improve your Git (and GitHub) knowledge at a radical level. A course that helps you feel less frustrated with Git. Launching May 21, 2024. Join the waiting list!
