课程概述

Much of the world's data lives in databases. SQL (or Structured Query Language) is a powerful programming language that is used for communicating with and manipulating data in databases. A working knowledge of databases and SQL is a must for anyone who wants to start a career in Data Engineering, Data Warehousing, Data Analytics, Data Science or Business Intelligence. The purpose of this course is to help you learn and apply foundational and intermediate knowledge of the SQL language, and become familiar with many relational database (RDBMS) concepts along the way. You will start with performing basic Create, Read, Update and Delete (CRUD) operations using CREATE, SELECT, INSERT, UPDATE and DELETE statements. You will then learn to filter, order, sort, and aggregate data. You will work with functions, perform sub-selects and nested queries, as well as JOIN data in multiple tables. You will also work with VIEWS, transactions and create stored procedures. The emphasis in this course is on hands-on, practical learning. As such, you will work with real database systems, use real 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. At the end of the course you will apply and demonstrate your skills with a final project. The SQL skills you learn in this course will be applicable to a variety of RDBMSes such as MySQL, PostgreSQL, IBM Db2, Oracle, SQL Server and others. No prior knowledge of databases, SQL or programming is required, however some basic data literacy is beneficial....

Terribly structured course. Method of theory delivery does not match the examples and exercises where you can practice what you have learned.

THIS IS MY FIRST EXPERINCE IN HERE. I CANT AFFORD THIS COURSES CERTIFICATE BUT I SEND AN EMAIL ABOUT THAT. I FINISHED THIS COURSE BY MEANS OF THEM. AFTER IF FINISHED THIS COURSE, THIS COURSE DIDIN'T FINISH FOR ME. BEACUSE I ALWAYS TRY TO LEARN ANYTHING ELSE BY MEANS OF HERE. I DECIDED TO STUDY ONE MORE TIME BY MYSELF. BEACUSE I WANNA BE A PROFESSIONAL LEARNER ABOUT THAT. I HOPE I WILL BE. BUT IF I AM A PROFESSIONEL ABOUT SQL, IT WILL BE THANK TO RAV AHUJA TEACHER. BEACUSE MY TEACHER TRIED FOR ALL OF US TO LEARN ABOUT ANY INFORMATION SQL. I WANNA THANK YOU MY TEACHER. BECAUSE THIS COURSE ASSISTED TO ME FOR LEARNING SQL. AFTER THIS COURSE I PROMISE I WILL STUDY TO LEARN THAN I LEARN NOW. THANK YOU FOR EVERYTHING. THANK YOU MHY TEACHER.

This course was a great introduction to SQL and querying databases. The content was well-structured and clear, providing a solid foundation in the key concepts of SQL, including SELECT statements, WHERE clauses, joins, and aggregate functions. I found the hands-on exercises to be particularly valuable, as they gave me practical experience in applying the concepts to real-world scenarios.

This course covered the basics of SQL very well and even offered to go into depth if we preferred. The hand-on approach really helped me not only to understand the concepts better but to apply them in solving real world problems. I would highly recommend this to anyone who would like to learn SQL with practical experience as it provides a solid foundation to build up on.

Excelente curso, lo mejor es que permite manipular una DB desde los aplicativos, que son manipulables y entendibles, lo cual lo hace demasiado interesante porque uno aprende mediante la práctica.
