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.

The course was very thorough and followed a good structure of learning. It took me longer than suggested as I was making notes as I went, but I really feel I got a lot out of it.

El contenido del curso parece interesante, pero está muy mal estructurado. Utiliza ejemplos, tablas, datos del los cuales no disponemos. El contenido parece interesante pero se hace muy difícil seguir el curso cuando hace referencia a objetos que no disponemos. The course content looks interesting, but it is very poorly structured. Use examples, tables, data which we do not have. The content seems interesting but it becomes very difficult to follow the course when it refers to objects that we do not have.

Great cause however I was unable to work with the data set and had to create my own dataset. It would be great if all the videos dint work with the data set that was on restored

Overall, I liked the sequence and instructions discussed in each section as one chunk at a time. However, I felt the missing part was the connecting string of isolated dots. There should be a more extensive test database and a more detailed problem statement. Learners should be motivated to attempt one major assignment touching upon the various facets of this course.

Good course in SQL. Covers diverse aspects of the SQL and DB in some depth and does not only concentrates on queries. Perhaps more interview specific queries can also be added as a bonus lecture to make it even better. Thank you!

I will keep increasing the stars as I progress the course. Till then Abhisekh and Pukhraj have some patience. I am a great admirer of both of you guys.

This course is my starting point for using SQL, and I feel that it gave me a very comprehensive breakdown of the basic skills I need to use it professionally. The tutorials were very informative, and I feel that more demonstrations for more complex queries similar to the ones needed for the assignments would be helpful as well. I also noticed that the lectures titled "What is SQL?" "Tables and DBMS," "Types of SQL commands," and "PostgreSQL" seem to be introductory lectures, but are found in the Final Section of the course. Overall, a great course, and I'm glad I took it!
