課程概述

Much of the world's data resides in databases. SQL (or Structured Query Language) is a powerful language which is used for communicating with and extracting data from databases. A working knowledge of databases and SQL is a must if you want to become a data scientist. The purpose of this course is to introduce relational database concepts and help you learn and apply foundational knowledge of the SQL language. It is also intended to get you started with performing SQL access in a data science environment. The emphasis in this course is on hands-on and practical learning . As such, you will work with real databases, real data science tools, and real-world datasets. You will create a database instance in the cloud. Through a series of hands-on labs you will practice building and running SQL queries. You will also learn how to access databases from Jupyter notebooks using SQL and Python. No prior knowledge of databases, SQL, Python, or programming is required. Anyone can audit this course at no-charge. If you choose to take this course and earn the Coursera course certificate, you can also earn an IBM digital badge upon successful completion of the course. LIMITED TIME OFFER: Subscription is only $39 USD per month for access to graded materials and a certificate....

For a beginner it is an excellent course. Step by step hands on examples help one to negotiate and learn patiently. Now I have much better understanding of why DBMS is so critical and how one has to use the cloud DBMS remotely. How the tables are created and the significance of Primary and Secondary key. How the queries are run. How to do the joins to handle data from multiple tables.

Its a very good course. It has both video lectures & hands on Lab simultaneously make learning effective & boosts confidence of a learner. Some issues with lab like unavailability of them due to technical issues makes thing somewhat inconvenient. But coming to learning, course is very good. I would like to thank the instructor & coursera also to provide such opportunity for students.

I was basically a newbie coming into this course. I was not great at SQL, and relied heavily upon others to handle writing queries for my reporting. Now, I feel like I can handle quite a lot, and can logically piece together anything I don't yet know. The class covers all of the core fundamentals through joins, and even covers ibm_db api to run queries using Python. Excellent course.

Classes have been short and very helpful and descriptive, and the hand-on lab practices give a perfect chance to practice all the stuff whatever we learn so not just concept but we get practical experiences.. however the assignment was a little tough but without hard work and getting stuck it will be worthless learning. Just wanna thanks all of the creators for such a great course..

The course is very good and informative. I have been facing one problem nothing with the course actually I had subscribed for the IBM professional Certificate for Data Science. Having completed this course has completed the set of specilization of introduction to Data Science but I have only received the certificate for the specializtion and not the badge. Kindly look into it.

This course is an excellent material for those who want to learn or excel in the field of DATA SCIENCE or more particulary DATABASE part of data science and perform various operations on large data persent in the from CSV or other file formats, by loading them into DATABSE and manipulating on analyzing data with help of some powerful progamming languages such as python.

A good course to learn basics of Databases and SQL so as to facilitate analysis and visualization of data to make effective decisions. I thank the professors to make this course interesting and worth it. Only thing is, videos can be made in a better way so as to facilitate people with non programming background. Maybe some basics of programming would help.

The course is really good, especially for beginners, which was my case. The course has direct and easy-to-understand lessons and several exercises where I was able to put the teachings into practice. I could learn the concepts related to databases and the most important SQL functions, and how to access and manipulate databases on any server using python.

Very good course with a lot of nice practical Labs.

Can't understand negative reviews on cloud solutions not working or missing information for the final exam.

The db2 database from ibm cloud was working fine and If you thoroughly go through every lesson, lab and exercise, you are perfectly prepared and able to do even more, than is needed to pass the exam.

The course is a real blessing to my data science. This is the most interesting course I have done in coursera series. I commend the organizers - IBM and the coordinator for a job well done. The course is not focused at setting a hard exam exam, but on procedures to solve real world problem. The cloud computation is also interesting and encouraging.

Course is good for any novice who wants to start with basic understanding of SQL.

It also covered database connectivity with python.

From my side i would like to recommend that course material should include some string functions like instr, substr and handling null values, as these are frequently used functions when working with any dataset.

Totally recommended for those who want to learn about the key aspects of relational databases and SQL for Data Science. The optional labs that are offered in the course are really helfull and have relevant information too.

In my experience, in this Specialization Course I found the key aspects for developing a Data Science project.

Course was structured really well and provided plethora of hands-on labs, particularly for Jupyter Notebooks and SQL Language which helped make the learning experience easy to follow. Videos were short and packed with lot's of information. Overall, a great course for beginners who are looking for a career start in Data Science.

The course is pretty good and consists of step-by-step classes which learn us basic skills we are going to use and evolve in our real job: what is a query, how we can use and create it, how to obtain data from a database, how to check out some particular data from a database, and so on.

Many thanks for such interesting course!

It was so hard to work with Pyton, because I did do it before. Oh,... I missed this job (work with SQL)!

Thank you for these course! It was hard, boring when you don't understand something (or can't fix your mistake cause you can't find it! (haha) ), but it was a real good time for refreshing my memory and learning new ways.

This course provides good basic knowledge in Data Base and SQL (Structure Query Language). Even i don't know anything about Sql but after taking this course i got basic knowledge and to practice sql queries IBM itself provide their database DB2. I would say thanks for providing such brilliant course IBM and CourseEra.

This is an action packed course with labs to help learners to internalize lessons learned in theory class. The course is highly practical. The student must have an open mind to learn, and prepare to explore various concepts that are connected. Everything is fun. It is a fast moving course and I thoroughly enjoyed it.

I express my gratitude to the organizers of the course. The course was very exciting.

I discovered a lot of new things in working with databases. This is a new science for me. I realized that I need to deepen my annia in programming. Now I plan to take your Python for Data Science and AI course.

Thank you good luck

The best taught course in the Data Science professional certificate curriculum.

Everything is aptly incremental, every question, every slide, every week. You wont click the next button and be surprised by the information on that page!

Unlike the other courses I didnt question myself - am I supposed to know this?

This course is the most interactive learning experience I've had on Coursera. Thanks to the brilliant teachers from IBM and the great course they provided. The most memorable thing was the labs where I was able to experiment the knowledge myself. Would definitely recommend this to anyone starting to learn SQL!

I am a beginner when it comes to SQL and relational databases so the course is just right. It may feel a bit boring at times but that's the nature of the subject not how the course is written. Some repetition is good to refresh memory. I would definitely recommend this class for anyone new to SQL or Python.

I wanted to learn a little bit of everything about SQL queries and I found exactly what I was looking for. The lessons were quick, packed with information and challenging. When I combine this knowledge with what I have already learned in Python I feel like I am well on my way to bigger projects.
