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!...

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.

A comprehensive course that covers major aspects of query building and retrieval in a management system. The topics were delivered well and the materials/assignments were relevant for skill-building.

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

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.

should have provided more explanation and help for exercises and assignment questions. The lecture is also not in depth enough.

Course schedule was good , but content is a little short. To make improvement, should present some example during the video

This is a good course for basic knowledge of SQL but the quizzes and assignments are very confusing and badly elaborated.

This is a good course on SQL for Data Science. As you will particularly start from scratch and go uptil tedious methods

The overall format was quite good but it would be more helpful if more examples are included in the lecture videos.

This course is helpful for beginners, but I felt that some explanation weren't clear and quizzes were challenging

More explanation of concepts is required. Also it would have been better if SQL code was explained in depth.

Instructor should have explain each code by performing practically on pc instead of showing only image.

not really relevant to 'data science' its more of a general basic introduction to CRUD and joins

創建者 Ayush K J

examples for important concepts were lacking like the use of GROUP BY and CASE statements

Clear instruction, but quite easy. Would prefer if it was more challenging.
