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!...

This course has really helped with optimizing queries that I work with everyday, enhancing my understanding of RDBMS, joins, analyzing and structuring exactly what you need and yielding those results.

I thought this course was great! Great introduction to Relational Databases and SQLite. Highly reccomend for anyone new to SQL, Databases, or someone looking to get started with a data science career.

Overall, it's a great course to be introduced to SQL without any background knowledge. However, lectures in Week 3 is hard to understand, which I need to seek for other sources to learn on my own.

The course gives us the basics of SQL only wrt Data Science. It does not tell us much about SQL. Would have liked if more information was given on SQL and how that works. All in all, good course.

Certain quiz questions were unclear. Final peer-review assignment had unclear/ambiguous questions that didn't fit with the data in my opinion. But content is useful. Delivery could be improved.

The course is very well planned with all the basics required to run a query in SQLite. But on the other hand, when it came to the last modules the class just takes off with very few examples.

Strongly suggest adding more example code and its running result which will make more sense for beginner. And more exercise problems as current Quiz do not cover all the points in the lecture.

There should have been more worked examples of queries as it would be hard for a fresher to fully understand it. Btw the Yelp Database lookup page was very helpful to play with the dataset.

The curse structure was well-drafted. However, the lack of interaction with the moderators was disheartening. The reading material linked is dated and the course needs an overall update.

Too lengthy unnecessary explanations in the beginning and the end of every video lecture. There is no platform to execute during the lecture what the instructor is showing in the video.

The quizzes will expand your knowledge more. writing and running codes during lecture videos could have made it more easier to understand though, this is what is missing to get a 5 star

You learn the basics of SQL but the course is a bit slow and repetitive, and the last peer-graded assignment should be graded by a computer or the TA's, not just random participants.

Great Course to start with.

Gives a good understanding of SQL on one side en working with databases on the other.

A syllabus of al the code examples in the video's should behelpfull

Final assignment has many questions that are unclear. Difficult to find answers in discussion forums, forums are poorly moderated, most questions have no useful answers.

Overall good course. The lectures could be made a bit interesting and engaging with exercises broken up. Found the lectures monotonous however course material is good.

I think there are not enough examples to help students learn the syntaxes deeply. It seems that some examples that students can code simultaneously can help more.

Videos were lame and didn't bother withe examples much but exercises were good to learn basic SQL (although u can learn same thing from google if not better)

The course starts easy and okay but the last assignment was so difficult. Quiz on what you teach and teach what we failed to understand (Assignment 4) part 3

This is a good intro course. Sometimes some of the content is covered too rapidly and needs additional supportive exercises to truly master the content.

Course instructor needed some improvement. It felt as though she was reading from cards the whole time and not really adding much value to the course.

Week 3 was a bit difficult. The questions asked in the quiz were little different than that which were in the lecture video. Rest everything was fine

The quiz questions does not match the material provided in the course. There are more easier ways to coding rather explained throughout the course!

The topics are well explained but the videos are monotonus (slides and the teacher talking). I think the course could be more interactive.

Good for learning basics of SQL but not much application and integration of concepts. In general, however, it is good for beginners.

Course would be much better if you can work alongside the instructor. Using presentation slides in a coding class is not ideal imo.

The lecturer maybe is a good data scientist but does not have the skills of presenting or explaining material in an easy manner.

Good course overall, but the gap between what is tought and how complex some of the application can be is frustrating at times.
