课程概述

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 loved the practices. I learned alot But I think some of them had mistakes... The online visual studio code never worked for me! It might be good to make a video that explains how to work with it.

Good course for beginners.- classes are fine- quizzes evaluate quite well your understanding I think- the final assessment contains plenty of VERY ambiguous questions and I think it should be reworked

It is a well structured and detailed course in terms of data analysis, SQL principles and differences between relational models (ER) and NoSQL. The difficulty level is between novice and intermediate and the instructor is very helpful and analytical. Overall recommended.

I believe this course is perfect to have a first approach towards SQL. Moreover I like how it relates to Data Scientists' context, and how it helps to understand Data Scientist's role and mindset. In general it was very useful and easy to follow lessons given by Sadie!

This was a great course, it provided me with great examples not just in the Instructor notes but in the side reading material that I have taken and created a review reference folder for future review. This is a great class and and I am glad it is apart of the program.

Best course I've taken on Coursera. Everything is so well done. Best learning experience when it comes to SQL when compared to all the googleing, youtubeing, other cources I've taken. Made me feel like I can actually take these skills to the bank. Thank you so much!

Если ты можешь перевести какой-нибудь технический текст = БЕРИ и не думай.

Параллельно смотрел лекции, тем самым дополнял знания полученным на курсе.

Иногда было сложно понять, что конкретно от тебя хочет программа, но можно несколько раз перечитать и все будет окей.

A good amount of info for a basics course. I would have liked a bit more detail and examples when the more complicated concepts came in (joins, more specifically).

The final assignment is pretty challenging but interesting and satisfying once you reach your results.

It is a very good course for beginners who want to learn SQL. It starts from the very basics and no previous knowledge is required. The instructor is really great and the lectures are informative. It will benefit anyone who wants to start learning SQL from scratch.

I am very pleased with this course mentor as she has a very clear speech. The data is split into many small videos that are overall quite easy to digest. The tests and exam has forced me to learn the material in depth and leaves me with a sense of accomplishment.

I had already some experience with other databases and higher education on science and I founded it interesting enough, not very difficult, easy to follow, do not expect very challenging things. All in all, I have learned a lot and I am satisfied. I recommend it.

The course is a thorough introduction to SQL, with particular emphasis on its capabilites and limitations from the perspective of a Data Scientist.

Very rigorous yet practical, clear and with significative examples and exercises that help consolidate the theory

The lecturer is great and her pace of teaching and examples are worthwhile!!!! It's very easy to grasp the language if you have previous knowledge of a programming language but still the way and the pace she teaches can make anyone learn and fall in love in SQL.

This is one of the excellent courses that I have done with Coursera with lots of coding quizzes and a proper final week assignment. I had no idea about SQL last week, and now I have learned the basics of SQLite, data profiling, and data analysis in this course.

This course was all what I needed, clear concepts and application to real problems. I was able to apply this in my job. I really recommend this course for anyone with certain level of familiarity, because also has some difficult exercises that allows learning.

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.

Ich habe 5* gegeben, da dieser Kurs sehr gut aufgebaut ist und ich dadurch meine Kenntnisse sehr verbessern konnte.

Da ich aus Deutschland bin und englisch nicht meine Muttersprache ist, habe ich mich etwas schwerer getan den Kurs zu bearbeiten.

Top Dozentin.

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 love this course, It is interesting, easy to follow, and practical, you learn a lot of Data Bases and SQL. The videos and source of information are so explicative, it's so easy to learn and apply all this knowledge in the practice quizzes and projects.
