Udacity SQL nanodegree review

Are you interested in learning more and specializing in SQL? If you are thinking of learning SQL from Udacity then it’s highly recommended to read the Udacity SQL nanodegree review before purchasing the course so that you can carefully decide whether the course matches your expectations or not and if it’s really worth it. 

Before we go through this Udacity SQL Nanodegree review, I highly suggest you to have clear knowledge on basic fundamentals of computers and different data types as without this, you would face difficulties in completing the Udacity SQL nanodegree program. 

First let’s get to know what Udacity is. Udacity is an online educational platform that gives access to a wide range of technical and programming languages courses to students of almost every country in this world, irrespective of their language and learning level. 

Each course is known as a nanodegree as it primarily focuses on one subject which is designed to be completed within a few months. They are packed with live projects, quizzes and training that prepares you well for real life tasks and applications. 

Along with that you get a mentor, career prep and mock interviews, self-paced online learning, career database with recruits, GitHub portfolio, LinkedIn profile optimization and many more benefits. 

However, you cannot access the course material again once you complete your nanodegree which is very upsetting for many users. 

With that being said, the Udacity SQL nanodegree program requires a proper study schedule and dedication, failing which you won’t be able to complete the course on time. 

Course Duration:

According to Udacity, this SQL nanodegree program is estimated to be completed within 2 months if you choose to devote 10 hours per week in this course. That means devoting 1.5 hours each day. 

However, as this is a time flexible course, you can take your own comfort and convenience to complete this course. 

Prerequisites for this nanodegree:

Although SQL is a programming language, this nanodegree program doesn’t require any kind of special prerequisites apart from having basic fundamental knowledge on computer skills such as operating systems (Windows and MacOS), word processing programs (Microsoft Word, Google Docs, PDF), presentation softwares (PowerPoint, Keynote, Google Slides), Spreadsheet programs (Microsoft Excel, Google Spreadsheets). 

It is recommendable for learners to have their concepts cleared on various data types for identification in a data table easily which includes strings, integers and many more. 


The Udacity SQL nanodegree program comes with two courses – 

  • Course 1: Introduction to SQL

As this is the first course of this SQL nanodegree, it starts off with basic SQL commands such as SELECT, FROM and WHERE and logical operators such as LIKE, AND & OR. 

As you proceed further, this course elaborates about SQL Joins and SQL aggregations, various types of subquery placement and formatting, using temp tables for accessing tables with multiple queries as well as writing subqueries to run multiple queries together. 

At the end of this course, you will understand how to use the correct data cleaning method for analyzing goals you set. Not only this, you will also understand how SQL Window Functions, SQL Advanced JOINS and Performance Tuning works. 

  • Course 2: Management of Relational & Non Relational Databases

The second course starts off with normalizing data, data definition language (DDL) and data manipulation language (DML). 

As you proceed further in this course, you will know the ways to implement business rules at the database with the help of SQL commands such as CONSTRAINT, UNIQUE, PRIMARY KEY, CHECK as well as formalizing the relationship between different tables using SQL Foreign Key with its variations

Along with this, you can fix slow SQL queries as you introduce database indexes with SQL command CREATE INDEX and learn ways to introspect SQL queries with the help of query planner EXPLAIN AND EXPLAIN ANALYZE. 

Finally you will conclude with an introduction to non relational databases that will teach about add, modify and query data in a MongoDB database, correctly using the MongoDB design patterns for practical situations as well as how to use Redis and add, modify, and query data in a Redis database. 

Both the courses involves two separate projects which are described below-


  • Project 1: Deforestation Exploration

As the name of the project suggests, you will work on raising awareness about reducing deforestation around the world by working as a data analyst for this project. 

You will start off with cleaning different erroneous values in a table, linking the same with another lookup table so that it can produce a fresh categorical and quantitative variable that will return all new categories’ view that is greater than the reference value. 

Furthermore, you will create and execute SQL queries to do calculations with the help of variables from disparate data sets that will answer queries for stakeholders. 

Finally, you will summarise your reports and answers that will help you to understand the countries and different regions with maximum cases of forest deforestation as well as the places with large number of forests. 

  • Project 2: Uddidit, a social news aggregator 

This project consists of developing supporting data structures for Uddidit, a social news aggregator website. 

You will firestly work on investigating the given data model to determine errors like lack of consistency rules, proper indexing, normalization and so on. 

Secondly, you will use DDL to create a new normalized database that is based on the provided denormalized database. 

Lastly, you will write DML queries for migrating the data from the normalized schema to their normalized schema. 


There are three instructors for this SQL nanodegree program. They are Malavica Sridhar (Project Manager, WAYMO), Ziad Saab (Software Developer and Co-founder, DecodeMTL) and Derek Steer (Co-founder and CEO, Mode Analytics). 

All of the three instructors have decades of experience working with SQL and are highly proficient in their field of expertise.

How Much Time and Money You have to Spend in Udacity SQL Nanodegree Program?

Based on the estimated time given on the official Udacity website for this SQL nanodegree program, it will take approximately 2 months to complete this course if you devote at least 10 hours a week. This would cost you something around $500. 

Udacity provides two options for payments; the first is to pay the complete amount at one go or else pay EMI of $300 (approx) for two months. 

However, if you want to save your money as well as your time to finish this course, you have to improve your productivity and plan your schedule beforehand. 

As projects take a considerable amount of time to complete, you need to ensure that you watch the project related lectures at least twice so that you can understand the concepts well and proceed with the necessary applications successfully. 

As Udacity has estimated a minimum of 1.5 hours daily to complete the course in 2 months, you can try to invest more time like 3-5 hours daily so that you can complete this nanodegree within a month.

  • It is not supported on Android and iOS operating systems so it is not possible for you to access the program on mobile or outside your residence. 


This is the complete Udacity SQL nanodegree review which consists of the course topics, projects, duration, money, as well as the pros and cons. 

I believe that Udacity is a really good online platform to learn about SQL and other programming languages if budget is an important issue for you.
