Udacity SQL Nanodegree Review- Is it worth it in 2023?
SQL, or Structured Query Language, is a language used to write data-driven applications. It allows you to structure your data in a way that makes it easier to read and query. SQL also makes it possible to manipulate data using functions and variables. SQL is a very powerful language and can be used to manipulate data in many different ways. But it’s not always possible to understand what SQL is doing when you are writing the code. Luckily, there are tools that make it easy to see exactly what SQL is doing at runtime.
SQL Server has a built-in SQL Analyzer called the SQL Server Management Studio (SSMS). SSMS is very powerful and is used to run many different types of queries against your database. For example, you can run queries against tables and columns to get a list of the rows in your table. It s also possible to run queries against data stored in your database using the SQL Script feature.
In this Nanodegree Program, Perform analysis on data stored in relational and NoSQL databases to power strategic decision-making. Learn to determine, create, and execute SQL and NoSQL commands to manipulate and dissect large-scale datasets. Begin by leveraging the power of SQL commands, functions, and data cleaning methods to join, aggregate, and clean tables, as well as complete projection tasks.

What you will learn in this Course – Course Breakdown
Now let’s come to the most important part of the course which is the course itself and what you get in it when you enroll in this course. This Course has a total of two sections each explaining some important topics related to the course and providing with you learning points and real-world projects at the end. Let’s take a deep dive into the sections -:
Intro to SQL
In this section, Discover the core SQL commands to initiate operations, select, modify, impose, arranged, aggregate, and join data tables and data. Determine that you have to utilize subqueries, several window functions, as well as partitions to execute complex tasks and cleanse data. Cleanse data, optimize SQL queries, and write select advanced JOINs to boost data analyses. Enumerate instances for which you would use the proposed methods and apply the results from queries to solve business problems.
SQL is a popular tool to manipulate and analyze data to inform decision-making. In this project, you will serve as a data analyst for an organization whose main priority is reducing deforestation in other countries.
Management of Relational & Non-Relational Databases
Databases must be completely organized so data can be easily queried and analyzed. Make normalized, consistent, and effective relational data models. Use SQL Database Definition Language (DDL) to build the data schema of a relational database designed for Postgres and apply SQL Database Manipulation Language (DML) to migrate a database from one schema to another.
The capabilities provided by relational databases and their non-relational counterparts can be distinguished. Learn the tradeoffs between both types of databases and decide on one that’s best suited for specific circumstances. Learn the differences between the two NoSQL systems MongoDB and Redis to gain a basic idea of their behaviors and requirements for non-relational databases.
In this project, you’ll build the supporting data structures necessary for Udiddit, a social media news website. First, you’ll evaluate the provided data model to look for errors such as lack of normalization, consistency rules, and proper indexing.
How long will it take to finish the course?
According to the Program, the course is expected to be completed within approximately 2 months if you devote a minimum of 10 hours per week to the course. As we mentioned above, they have a self-paced learning environment, so you can attend at your discretion and at your pace.
If you take more than 2 months to finish the course, you have to take the monthly pay-as-you-go plan and pay extra which will increase your overall cost of the course.
What’s the Cost of the Course
Now let’s talk about the cost of the course which is an important part of whether you will buy or not buy the course. In this course, Either you will pay for monthly access or you can also choose a 2-Months access plan.
If you choose the monthly pay-as-you-go option you will pay $399 per month and there is another option that you can choose which comes with exclusive discounts which is a 2 months plan that you need to pay upfront and costs you around $678 which comes with exclusive discounts making it cheaper than the monthly plan and also recommended by Udacity.
If you pay upfront for the 2 months’ access you can save up to 15% + 70% exclusive discounts which you cannot if you take the monthly plan. If you need more time after 2 months, you can switch to a monthly access plan but it will increase the overall cost of the course.
Exclusive Discounts
Udacity will give you personalized Discounts if you answer 2 questions and pay upfront rather than a pay-as-you-go plan. You will get a promo code with an exclusive 70% Discount just for you on your course by just answering 2 simple questions.
What Other Students have to say about the Course
While looking at ratings and reviews of this course, One has to say that this course is very popular among the students with an overall rating of 4.6 out of 5 stars, and many good quality reviews are given by already enrolled students in the courses. Some of the reviews are -:
“The only thing I can say so far it is that is fulfilling my expectations (although I have already done twice this course when it was for free, probably the good impression from the free course was the reason I enrolled in this one). As I said in some lesson review, I think the new update (from Derek material to the new one, specially on last lessons), has a lesson which, personally, I think it is better explained (Window Functions and SQL Advanced JOINs & Performance Tuning) and other where I have missed a little bit more of quiz in the first part of the lesson (SQL Data Cleaning).-FJ S.
“The program is great! I love the self pace atmosphere and the knowledge center to help guide you along the way, if you get stuck. The feedback is provided within 1 day and I love the suggestions provided by the reviewers. They give you handy guides to continue to perfect your work along the way.
I also love the fact that if you are wrong, you have an opportunity to see where you went wrong and correct your answers. This provides the student with ongoing courage and support. I would suggest they focus a bit more on ways to shorten your queries with more advanced clauses / queries and provide more details around quartiles. Hoping to past the last project by EOM. Overall, great experience!”– De’lazurae C.
