Über den Kurs

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 enjoyed this course and really learned a lot. I loved being able to go at my own pace and start the course over if my schedule was too busy. You can do practice quizzes as many times as you want and you are given opportunities with extra time to redo your quizzes. This format gives you a great opportunity to learn and at your own pace which was awesome.

This course is an absolute hands-on class! All theory is based on practice and real examples, which makes it is easy to understand and immediately imagine the situations, where you would use the described "method". Definetly I would reccomend this course for the people who are new to this theme, but wants to explore the world of SQL precisely! Take care!

This course has an amazing structure. It allows and highly encourages to think like a professional and provides resources that allowed me not only to pass the course but will also be relevant when I move ahead in this skill and career path. The assignments are also very well designed. Passing the final assignment gives a lot of confidence in the subject.

Muy buen curso para empezar a tocar SQL. Tanto las pruebas intermedias como la final te ponen contra las cuerdas y te obliga a utilizar casi todo lo aprendido. Si no has programado nunca o empezaste y lo dejaste te aconsejo tener algo de paciencia para completarlo. Entender cada video y cada paso que das. Sin lugar a dudas escogeré el siguiente curso.

The concepts in this course are explained very well and are very descriptive. They are taught step by step and she also gives an explanation as to why we use these concepts and why theyre important. I was able to delve deeper into SQL and was able to acquire the basics in order to solve real life SQL problems. She is one of my favourite instructors!

Good points: Provide the knowledge from zero, Always clarify the learning objectives, Good assignments and grading system, and Final assignment with peer-reviewed system is cool!

Weak points: The number of examples is not enough, Should have a pointer on the screen to make the learner understand more easily

Overall, Impressive!

Thank you very much

Great course for anyone who wishes to understand how SQL works with relevance to data science. This course will set you up for advanced data mining using SQL. The topics covered in this course are sufficient for understanding a proper working of SQL. Other than that , you will have to practice to get good at it.

But overall great course. Kudos.

Even though this course is aimed at beginners, the assignments encourages a person to do some additional research. This simulates how a person should continually research and explore to enhance one's knowledge and experience. The final peer graded assignment was fun. Make sure you allow enough time to spend on it and you will reap the rewards.

Really great introductory course to SQL. I highly recommend taking this course for those who have little to no experience with SQL. All of the course work and material was easy to comprehend and very digestible. In addition, the quizzes and assignments were great supplemental exercises to reinforce the concepts that were taught in the course.

Today in the morning at 7:00AM EDT I was so happy that I can't imagine, Sadie made me positive and passionate in my career. Because of her, I can now achieve my dream to become a data scientist and learn more and do good in life. Hopefull! This is the best course of SQL hands down! I failed many interviews but now I am sure I will pass it.

I really enjoyed the course as per the content and the review questions at the end of each week! I have learnt a lot to build on and can't wait to practice SQL and use it in my work. I totally recommend it to anyone who needs flexible hours to learn how to deals with big data and to learn how to retrieve and be tidy with the data in hand.

One of my favorite courses on SQL so far. I would definitely recommend it for beginners as well as those who want to brush and broaden their knowledge in databases and query optimization. The instructor is highly knowledgeable and very well articulated. I have enjoyed the course so much because of the clear presentations and explanations.

The course is simple and clear for a beginner. The slides,video and notes are helpful and it guides me slowly to understand different SQL syntax and its applications. The quiz and assignment are really good platform to practice all the knowledge i learnt from those 4 courses. Lovely! Highly recommend to others who never learn SQL before.

Some of the beginning is a little too easy. The last assignment of week 4 was much more time consuing than anything else - expect to take 5+ hours if you're going to do a fantastic job. You could probably rush through it in less than 2 hours but as a peer grader, I could tell who rushed through, and who took time to do a fantastic job.

The course provides a lot of useful material and additional resources. The lessons are clear and interesting and help the students stay on track and keep learning. With a considerable amount of time practicing what I've learned during lessons, I think I have understood the underlying principles of SQL which I can use in the future.

The course was well explained. I struggled a bit with some topics like combining multiple joins and subqueries. A few additional examples in the form of a case study might have helped understand the concepts a bit easier.

The quizzes , projects were all good practice making us think and apply the knowledge we gained.

Thank you.

Coming from non technical background I have faced many challenges in past specially when dealing with big chunk of data into Anti-Money Laundering domain. Now at least I can eliminate dependency from IT team to run queries and extract data for me. I can manipulate and filter the data on my own as per the business requirement.

Lectures were greatly oriented and well presented. The content was brilliant and perfect for a beginner. It was eary to understand. The assignments were quiet challenging especially the peer graded one. Overall the course really helped learning and practising SQL and tested whether we have learnt something from it or not.

I took a different Data Analyst Professional Certificate on Coursera, but this class actually taught the fundamentals of SQL and how it works. It made sense! This is the first in a series of four courses...Now I am excited to go to the next course rather than wanting to pull my hair out after the last program I was in.

This course was my first experience with this type of learning and it went so far above and beyond my expectations. Sadie is an excellent teacher and I found the course very easy to follow and interesting. I feel that I learned a lot in a short time and would highly recommend this course to anyone looking to learn SQL.

Great course. Final project needs some work and this course will be top notch!! For the project, it would be great if we could port the data into R or Python and do some sort of basic analysis of it. Would make it more interesting. I like the separate coding and concepts quizzes. The teacher is amazing and upbeat!

Very useful for beginners who don't know anything about SQL. You will learn basic things that are necessary, although sometimes these videos won't be enough and you have to do little research by yourself (watching videos on YouTube and reading some tutorials). Overall it's very interesting and with a lot of practice.

Good introduction to learning SQL, data science best practices, and tools to continue developing this skillset. The lessons and quizzes are well-organized and easy to follow, as well as give good food-for-thought questions to get the problem solving gears going. Would recommend to anyone getting into learning SQL.

The lectures videos are the right size. Assignments are too simple at times. Final peer-review assignment was decent difficulty and allows for a lot of involvement; it also introduces you to data analysis in a structured manner. Liked the course very much. I'd recommend it to beginners in SQL and/or data science.

I liked the way the material necessary for data analysis was presented and organized. I think there could be a bit more difficult exercises during the course to prepare learners better for final project and give them better idea what is expected in real world.

Overall, it was awesome and well designed. Thank You.
