О курсе

As data collection has increased exponentially, so has the need for people skilled at using and interacting with data; to be able to think critically, and provide insights to make better decisions and optimize their businesses. This is a data scientist, “part mathematician, part computer scientist, and part trend spotter” (SAS Institute, Inc.). According to Glassdoor, being a data scientist is the best job in America; with a median base salary of $110,000 and thousands of job openings at a time. The skills necessary to be a good data scientist include being able to retrieve and work with data, and to do that you need to be well versed in SQL, the standard language for communicating with database systems. This course is designed to give you a primer in the fundamentals of SQL and working with data so that you can begin analyzing it for data science purposes. You will begin to ask the right questions and come up with good answers to deliver valuable insights for your organization. This course starts with the basics and assumes you do not have any knowledge or skills in SQL. It will build on that foundation and gradually have you write both simple and complex queries to help you select data from tables. You'll start to work with different types of data like strings and numbers and discuss methods to filter and pare down your results. You will create new tables and be able to move data into them. You will learn common operators and how to combine the data. You will use case statements and concepts like data governance and profiling. You will discuss topics on data, and practice using real-world programming assignments. You will interpret the structure, meaning, and relationships in source data and use SQL as a professional to shape your data for targeted analysis purposes. Although we do not have any specific prerequisites or software requirements to take this course, a simple text editor is recommended for the final project. So what are you waiting for? This is your first step in landing a job in the best occupation in the US and soon the world!...

I think this course is amazing. They actually try to teach you very good quality information. They took their time to create good assignments and quizzes and a very challenging final assignment. I truly loved this course and I cannot wait to start the new one.

I really enjoyed the course. I have started from almost no knowledge about SQL and this course was really a big help on my way to mastering the SQL! It's still a long way to go, but I recommend it to any beginner, who wishes to take a step in data analysis.

Another great class from Coursera - very helpful exercises and final assignment, both of which really helped in learning the content that was nicely presented by the instructor. Without writing a lot of queries, it's simply not possible to really learn SQL.

Simple but also has a great introduction to SQL, focused on relative models and analysing demonstartion by joining tables with ER-models of real life dataset. The only downside is that it doesn't teach about the data manipulation, only retrieving is taught

I managed to properly learned back all the basics and there are certainly some of the things I never learned at the university. Overall, the course was magnificent. I properly learned how to code and made a thorough analysis like a real life Data Scientist

This is one of the best course available for learning SQL from scratch. Most of the part is explained thoroughly (Using "most of the part" because I felt "date & time" could have been explained into more details). Overall it's a good course to start with.

I enjoyed the course. Well structured, good questions to check knowledge within courses/videos. I felt my experience in R definitely helped me understand this better, but I believe that the class structure absolutely helped me get the basics of SQL code.

Excellent course. It helped me a lot to define some questions that I was not clear about SQL for analysts and data scientists. There is a good development of the topics seen in SQL, as well as good practices. One of the best SQL courses I've ever taken.

I started this course with no knowledge and now I feel I can Profile and analyze few data. Best for Beginners. The Instructor is good with the way she educates us. Only Suggestion is Help Us Install any SQL software so that we can practice more offline.

I previously took the Google Data Analytics Professional Certificate that was great introduction to SQL, but this course really reinforced the information with more information and practice. I highly recommend it if your trying to become a data master.

The course is really helpful to get a brief knowledge about SQL Queries & Several functions that are directly applied over SQL Queries. Even the course leads to a great work with data profiling & data analyzing at the end. Thank you Coursera :)..✌✌😇😇

Fantastic introduction to SQL. So easy to follow, and I really appreciated the concept check questions as you're watching the video--even if I got the answer the first time, this really helped cement my understanding of the concepts I was learning.

I learned everything of the most important programming language with only one MOOC . The course was so explainable from key terminology to SQL queries . I want to thank personally the coursera team and University of Davis for this amazing result.

This course was somewhat slow and theoretical in the first week, but starting from the second week, it became intensive and progressive. The final homework was extremely well designed, and it took a good amount of time for you to finish the test.

muy buen curso aunque los temas que se ven tienen pocos ejemplos practicos. Se ven muchos temas, en ese sentido es muy completo. Sally es encantadora y transmite pasión y entusiasmo.

El examen algo con cierta dificultad que no se ve en el curso.

This course is very beginner friendly. The concepts were explained well. Additional Reading materials were provided too in every module. In-video quiz, practice quiz and coding practice questions made it easier to revise concepts of each module.

For me, it was an excellent course to have a first approach to the software. Some exercises or assignments are difficult compared to the level of the course; however, you should make your own research and give your additional effort to solve it.
