  2. It is not really difficult to learn SQL. SQL is not a programming language, it's a query language. The primary objective where SQL was created was to give the possibility to common people get interested data from database. It is also an English like language so anyone who can use English at a basic level can write SQL query easily.

SQL is easy but no one can determine the learning time it takes. It totally depends on you. The method we adopted to help you learn SQL quickly starts from the basics and takes you to advanced level within hours. You can follow the same, but remember you can learn nothing without practicing it. Practice is the only way to learn SQL quickly.

What's the difference between SQL and PostgreSQL?
SQL is a language. Specifically, the "Structured Query Language"
PostgreSQL is one of several database systems, or RDMS (Relational Database Management System). PostgresSQL is one of several RDMS's, others of which are Oracle, Informix, MySQL, and MSQL.
All of these RDMSs use SQL as their language. Each of them have minor variations in the "dialect" of SQL that they use, but it's all still SQL.
Which is better, PostgreSQL or MySQL?
Both are excellent products with unique strengths, and the choice is often a matter of personal preference.
PostgreSQL offers overall features for traditional database applications, while MySQL focuses on faster performance for Web-based applications.
Open source development will bring more features to subsequent releases of both databases.
Who uses these databases?
Here are a few examples of companies that use PostgreSQL: Apple, BioPharm, Etsy, IMDB, Macworld, Debian, Fujitsu, Red Hat, Sun Microsystem, Cisco, Skype.

Course materials such as lecture notes cover basic to advanced SQL topics for SQL Database

you cant be mastering by learning this course

Yes definitely and the tutor is excellent.This all can't be explained in more simpler way.

The course is good for a beginner. it goes step by step and teaches in a very comfortable manner. The theory part should be placed at start of the course rather than at the end

The course has all for the ones who want to learn SQL at beginner level. The theory part should be placed at start of the course rather than at the end. Theory could've been much better and 2-3 things can also be added. Still, a great course to top up your SQL level

This is one of the best SQL Courses that I have ever come through, right from learning and understanding basics and implementing them practically, this is the exact way that you want to experience learning as a beginner!

very good lesson, very clear, i like this course to much..

The course is good for beginner. it goes step by step and teaches in a very comfortable manner. I have learnt a good deal from this course

Excellent match. I've been to University and studied MySQL but could never understand it. Ever since I started this masterclass, I have understood more than I have a whole year doing a bachelor's degree. Thank you

Great Concept description

I was doing ok until up about section 10, but the instructor is moving too fast. I am a complete learner and 4 weeks ago I knew nothing at all about SQL, so I cannot move as fast as he expects me to. Why doesn't he break down the very long queries into little sections by showing what each part of the query will produce (and then all together as one)? This would surely help a student to understand. It's all very well listing a huge 8 line query that we copy ourselves as he types it but when I am in need of this in a real life situation in the workplace am I going to remember this exact order of where every part of his query goes having done 1 example in this tutorial?This is just my opinion for what it is worth but the pace should be much slower, it should ensure the average student can understand and keep up with his pace so we do not become overwhelmed to the point where we do not want to continue. He is speeding through as if he is teaching himself at his own level and not considering the level of understanding of an absolute beginner. Yes you can say play it back but you cannot slow down the guys voice or change his accent, it doesn't make things any easier to listen again.After each exercise why not have a module each time going over the correct outcomes, how the queries he is asking you to attempt should be written and why, instead of just assuming I have had no problems with the exercises? If I haven't been able to complete it, tough luck then I guess, but the answer is here in a pdf, even though you didn't understand why. Frustrated.

Well explained, useful information presented.
