Working knowledge of SQL (or Structured Query Language) is a must for data professionals like Data Scientists, Data Analysts and Data Engineers. Much of the world's data resides in databases. SQL is a powerful language used for communicating with and extracting data from databases. In this course you will learn SQL inside out- from the very basics of Select statements to advanced concepts like JOINs. You will: -write foundational SQL statements like: SELECT, INSERT, UPDATE, and DELETE -filter result sets, use WHERE, COUNT, DISTINCT, and LIMIT clauses -differentiate between DML & DDL -CREATE, ALTER, DROP and load tables -use string patterns and ranges; ORDER and GROUP result sets, and built-in database functions -build sub-queries and query data from multiple tables -access databases as a data scientist using Jupyter notebooks with SQL and Python -work with advanced concepts like Stored Procedures, Views, ACID Transactions, Inner & Outer JOINs Through hands-on labs and projects, you will practice building SQL queries, work with real databases on the Cloud, and use real data science tools. In the final project you’ll analyze multiple real-world datasets to demonstrate your skills....




Amazing course for beginners! The entire course is well structured and has good hands-on assignments. SQL is extremely essential for Database management and fun learning so please do try this one out!



I am thankful to coursera for providing database and sql for data science course in such a way that anyone can

understand the basic fundamental of sql and database. I learn a lot from this course.

This is a very good introductory (and maybe even intermediate) course on SQL (with and without Python/Jupyter). I only miss more reading material to avoid going back to the videos - maybe the slides could be made available after each week.

創建者 Haraprasad D


This a very good course, it starts from basic and goes upto intermediate level. My feedback is - if it can cover more on data visualization then it will be great. Its 90% is on pl/sql , 10% is on visualization this ratio can be balanced.

I loved the training and the material as well. The only thing painful was doing the peer assignment, you need to take screenshot and then upload. It would have been easier if we could have just click on the Submit in the juypter notebook.

Awesome course to gain practical knowledge of using databases from the cloud with a jupiter notebook. The course was really helpful and helped to gain an overview. An increased thirst to have better knowledge/grip on the user perspective.

創建者 Debarshi B


Everything was well-taught with examples and labs. The quiz was created based on videos and labs, and the final project gave me a chance to revise everything. Overall, a 10/10 Course. Loved it. Thank you, IBM, staff members and my peers.

While this course is a demanding one, it is also quite interesting and well loaded with deep knowledge. I enjoyed every bit of it and I did not mind the time I had to keep up late some nights running Jupyter Notebook and querying data.

I had a challenging but fulfilling and wonderful experience in this course. Thank you so much, Coursera for helping me finished this skills. I gained so much confidence in SQL Db2 management and Python access. More power to your team!

創建者 Jafed E G


I enjoy the lectures. The professor has a good speaking and teaching style which keeps me interested. Lots of concrete math examples which make it easier to understand. Very good slides which are well formulated and easy to understand

This is a very complete course for building fundamental skills with SQL. I've really enjoyed the numerous hands-on practice sections which solidify the knowledge from the lectures. Plus the free-trial bonus for IBM DB2 cloud service!

創建者 Stuti D


This course was really helpful for me as it helped me in learning basic SQL skills with and without Python to a good extent. Would definitely recommend this course to anyone who is just starting out with learning Databases and SQL!

創建者 Diego M


Great introduction!

I had no experience with SQL at all. This course helped a lot in understanding many details about RDBMS.

I can now do many useful queries and have a head start when start to read a RDBMS book to deep my knowledge!

I had a lot of problems with the IBM Cloud platform. However, I have completed 5 courses with Coursera and I've never had any problem with the platform before. So I rated the course 5 stars due to the high quality of the content.

創建者 CHUA W K


This problem is excellent , i've totally no experience in programming but i still can success for the assignment ! be patient , re-watch all those videos , it will help you to understand the sequences and your assignment needed!

創建者 Pratyay R


in this course you will learn how to connect to a databse and then working on this database useing python,also learing , how to connect to a online data set useing python and many more my sql function like join,aggregate , etc

Although I have previous knowledge about SQL and databases, I have worked on Oracle 11g as well but by doing this course now i am able to connect IBM-db2 API with python. I have learned how to code in python to access databases

Me gustó mucho este curso, muy util para el manejo de bases de datos y la obtención de grupos de datos con características específicas dentro de los datos, asi como relaciones entre tablas y consultas desde Jupyter. Excelente.

創建者 Nikhil J


Definitely recommended. Great course, good basics, and assignments. But, IBM Cloud throws random errors sometimes when you try to open the db2 console (402, 502, 404). Just refresh it multiple times. Should solve the problem.

創建者 Anil k


This is best platform to improve your skills, i got to much practical knowledge to work forward for my career. i would highly recommend everyone , who is reading this, go for it. You would thank me later for recommendation..

創建者 Vladimir A


This course has great technical support and good material. The lectures are informative and understandable. I first met such a quick feedback from the course technicians. It 's a great cloud lab experience. You 'll like it.

創建者 Mukkesh M


This course starts with the basics and gradually covers most of the topics in SQL. The hands-on lab exercises are extremely useful and give the learner a good command over practical applications of SQL+Python architecture.

創建者 Chris A B


I enjoyed learning about Data Science and the use of Cognitive Class Labs, IBM Watson Studio, IBM Cloud, IBM DB2, Jupyter Notebooks and Python. I am looking forward to subscribing to the Professional Specialization next.

創建者 Bhanu P E


This is an excellent course covering end to end SQL and python/Jupytr notebook integration as this forms the basis of data import going forward. The Ungraded labs and Final assignments were really good hands on practice.

創建者 Jesús G A S


Probably the best course in the specialization thus far! Notebooks provided are invaluable to learn how to interface a jupyter notebook with IBM cloud. I had not found this information elsewhere in such a concise manner.

創建者 Andrew H


Not an easy course at all, but I learned a lot - very good overall.

Wish there was a bit more instruction of how Jupyter Labs and connections worked, but apart from that an edifying course which increased my knowledge.

創建者 Santiago N


Un excelente curso introductorio al manejo de SQL, explicaciones cortas y precisas, ejercicios muy prácticos y dinámicos, herramientas perfectas para la ejecución de los comandos, en genral un excelente curso sobre SQL.
