Building off of previous SQL courses, this course will begin to introduce the student to more complex database concepts. Students will learn to think about data as sets and subsets and practice achieving desired query results via such operations as inner and outer joins, unions and except. They will also be introduced to the concepts of Set Theory and Database Normalization to aid in understanding good query practices.
In this course you'll get lots of practice writing SQL queries in a realistic environment!
Learn how to create and modify your own database tables as we work through a real-life example! We'll talk about how to choose the right structure for a database and then see how we can implement that structure.

A database is a collection of data that’s organized so it can be accessed, retrieved, referenced, or recalled. A database can take the form of many different types of hardware: Servers, cloud infrastructure, individual computers, and more. Large companies like Oracle, Amazon, and others sell databases, or other similar types of infrastructure, for companies to store their data.

Recently started the Treehouse Front End Web Development Techdegree and it's by far one of the best things I've ever done.— Sheldon George (@sheldonjg) September 2, 2019
Day 18 of #100daysofcode. SO ready for the JS unit in the #treehouse FEWD Techdegree. I feel like JS, HTML, and CSS represent the three virtues in the Triforce. Now that I'm getting into JS... I'm feeling balanced ⚖️⚔️!— JoJo (@jowebdev2020) April 28, 2020
The @treehouse #techdegree gets you a much more in-depth experience, access to the Slack channel, peer-review, & building a (graded) portfolio of projects, PERFECT if you're a first-timer looking to get momentum to (as in my and @shilvia_88's case) make a career change. 🙂🏢👩💻— Ryan Whitney (@spaceman_ryan) February 14, 2020
11/100 #100DaysOfCode Working on JS form validation. So happy to be a part of the community @teamtreehouse techdegree. Fantastic to have some specific individuals to reach out to when stuff doesn't make sense to me and I don't have a teacher/mentor to ask😅 2/301 #301DaysOfCode— Maren Lilleberre (@MarenLilleberre) May 13, 2019
Data is everywhere. Online purchases, social media posts, and your playlist of favorite songs all exist as data stored in a specialized program called a database. To communicate with a database you use a specialized language. The most popular language for accessing database information is SQL, or “Structured Query Language.” SQL, also pronounced "Sequel", is the key to reading, adding, updating and deleting information in a database. With just a few lines of SQL you can search, analyze and retrieve data from vast archives of information to help a company run, make a crucial business decision, or simply get a list of movies you'd like to watch. SQL and other database programming technologies are used at companies big and small. Learning SQL will give you skills that can open doors to careers like data analyst, web application developer, and full stack engineer.
In Treehouse's blog, you can find a wide variety of topics that can further help you in your learning and application of new skills. For instance, you can look up “What Is Front-End Web Development?” And “Intro to Design Thinking” can help you tackle design.
