課程概述

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 enjoyed the course and learned a lot of fundamentals. There are some gaps about notation and an occasional unclear question that would most likely be addressed in a live class. Otherwise, this format worked well for this information.

Very good course! All the material, exercises and explanations were simple and easy to understand, but the final assignment was a bit more challenging which allowed me to reinforce what I had learnt throughout the course. Recommended!

Great class for a beginner with no SQL experience. I had already taken another SQL for beginners online class but got MUCH more out of this one. The instructor did a great job with starting with the basics and building upon them.

Great introduction to SQL- I knew nothing about the programming language prior and have minimal experience with writing code. The course was easy to understand and had great practice examples in the quizzes. 10 out of 10 recommend.

This is a great learning experience. Although I have learned Database System Concept during my undergraduate course, this course taught me something new and novel. This is my first course in coursera. Hopefully I can work harder.

Best thing about this course is that its syllabus starts with fundamentals of SQL and covered most of the concept of SQL. By completing this course you will be able to write data queries according to client or your requirement.

I find it very good to start SQL training. I was an absolute beginner and with a very lot of exercises, I believe that I covered a great foundation. Now it's time to continue building some more. I highly recommend this course.

I was so weak applying my sql knowledge before taking this course, but this course made me write many sql query which made me after that very confident enough to write sql query on my own.

Thank you so much for your support <3

A really good introduction to SQLite. Easy to understand but it would have been better if while the examples (codes) were displayed, there is a corresponding database so people can practice what they see and understand better.

A good course especially for the beginners. Part 2 of the assignment, however, is more intense than the expectations, incorporating some areas not included in the course, which I guess is to compel learners for more research.

Perfect to learn SQLite commands for the first time. The teacher explains all topics clearly and it is easy to understand and follow. Activities are useful and the peer-assignment is a good way of applying everything learned.

This course is useful for people wishing to understand SQL basic. The presentation is lively with simple example to replicate. Each section is from 5-15 minutes, suitable for people who do not have long time span each day.

This was a really solid class to understand and apply basic concepts. It requires that you put some work in, especially if you're less familiar with SQL, but it has been useful to me already in refining some of my coding.

A really good course. They have covered all the details starting from the basics and made sure you have understood everything through quizes. The quizes are also great and cover all the concepts taught during the videos

It was a great experience to have a course. It was my first ever course as Online. I am thinking that the journey has started and it will never end. I also have selected the next course that I will complete in the next.
