Acerca del Curso

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 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.

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.

This course is extremely helpful,4 start for that.Only if it had assignments along with the sample data to measure the range of our learning will be much helpful.

This course was good but I found at times the words being said didn't match the text in the video. It would have been more helpful "practice as you go" as well.

Lectures build at a slow, comfortable pace, but be prepared to discuss things on the message board, and read classmates' comments, or the quizzes will rock you.

The project required deeper understanding than what was taught in the course and a few minor details were missed while teaching how to apply different syntaxes

Really did help me understand SQL better. The main issue I had was with the final assignment, since the tool provided to analyze the dataset was very limited.

I wish there were more practice exercises in between the videos. It would also be more helpful if there were more visuals/animations to accompany the lessons.

Although the course was very hands-on, and the Instructor made everything clear I was left wanting some more reading material for learning about Data Science

Great course, provided a really good introduction. However they course could have provided some more examples as to how to actually use the functions taught.

More exercise will be much better. For now, it is not enough for the learner to apply their skills learned in this course so they cannot master their skills.

Overall content is good. But for the beginner who has no background, it would be more helpful to show the result of coding on each statement while teaching.

Great for begginers, I'd suggest to learn with W3 school sql tutorial in parallel as it has more concrete examples and functions you can try by yourself.

great course and really liked the instructor

the assignments made me think and re-visit material, but instructions were clear and the problems a good level

Great learning SQL basics. I took away a star because some of the later concepts like CASE were not well explained and I had to consult outside sources

Peer assignment needs to be cleaned up a bit. There is not a lot of overlap in tables due to the limitations yelp imposed but overall, very informative.

Everything was in the best order, i suppose, but at times I had to watch and read other content to get the concept completely. But good way to refresh.

Good course overall, I wish it had more work along with the teacher kind of work like on Linkdin. Otherwise there are some great tips and explanations.

Great course but there were typos in the assignments that made them hard to understand and the editor wouldn't allow things like INSTR and temp tables.

Good introductory topics. However, not a detailed introduction to any specific queries. This course is for someone who already knows few sql queries.

It's fun thing to learn SQL in the first place, but the instructor seem like just read the script maybe?

But I like the quizzes and coding assignments!

Overall this course is quite good to get a first understanding of SQL. Although i missed some more explanations or examples for complex data analysis.

The course is useful, but in my opinion there must be added more practice during the course and way more examples and explanations in week 3 module.

Some if the query running environments were not working on an iPAD. So it was very difficult to complete get answers. Otherwise this course is good.
