This course teaches you the essential skills to work with data using SQL. Focusing on querying, manipulating, and combining datasets, this course is designed to go from beginner to advanced. Using hands-on exercises on the Udemy platform, you\u2019ll start coding right away, without having to install any software. Throughout the course, you\u2019ll work as a data scientist at a fictional education company and learn how to use SQL to analyze data about instructors, students, and courses. The course includes short instructional videos, 40 coding exercises with answers, and assessment tests. Some of the topics covered include SELECT statements, filtering with WHERE, sorting with ORDER BY, joining tables with INNER JOIN and LEFT JOIN, aggregate functions like COUNT and SUM, and advanced Window functions with OVER and PARTITION BY. This course is suitable for people who want to learn SQL for practical data science applications.<\/span><\/p>\n<h3 dir=\"ltr\" style=\"text-align: left\" data-sourcepos=\"11:1-11:25\"><span style=\"vertical-align: inherit\">What you will learn:<\/span><\/h3>\n<ul dir=\"ltr\" style=\"text-align: left\" data-sourcepos=\"13:1-17:0\">\n<li data-sourcepos=\"13:1-13:48\"><span style=\"vertical-align: inherit\">Mastery of basic SQL commands such as SELECT and WHERE<\/span><\/li>\n<li data-sourcepos=\"14:1-14:81\"><span style=\"vertical-align: inherit\">Learn how to use aggregate functions to transform data and calculate new values.<\/span><\/li>\n<li data-sourcepos=\"15:1-15:59\"><span style=\"vertical-align: inherit\">Understand how to use JOIN to combine information from multiple tables.<\/span><\/li>\n<li data-sourcepos=\"16:1-17:0\"><span style=\"vertical-align: inherit\">Learn how to use advanced window functions to calculate more complex values.<\/span><\/li>\n<\/ul>\n<h3 dir=\"ltr\" style=\"text-align: left\" data-sourcepos=\"32:1-32:32\"><span style=\"vertical-align: inherit\">Who is this course suitable for?<\/span><\/h3>\n<ul dir=\"ltr\" style=\"text-align: left\" data-sourcepos=\"34:1-38:0\">\n<li data-sourcepos=\"34:1-34:48\"><span style=\"vertical-align: inherit\">Current or aspiring data scientists and data analysts.<\/span><\/li>\n<li data-sourcepos=\"35:1-35:100\"><span style=\"vertical-align: inherit\">Anyone who wants to learn SQL with interactive exercises and complete video solutions with detailed explanations.<\/span><\/li>\n<li data-sourcepos=\"36:1-36:77\"><span style=\"vertical-align: inherit\">SQL beginners who want to go from ignorance to mastery of advanced SQL commands.<\/span><\/li>\n<li data-sourcepos=\"37:1-38:0\"><span style=\"vertical-align: inherit\">People who want to write SQL code immediately using the Udemy Coding Exercise feature \u2013 no software required!<\/span><\/li>\n<\/ul>\n<h3 dir=\"ltr\" style=\"text-align: left\"><span style=\"vertical-align: inherit\">Course Details: SQL: A Step-by-step Introduction for Data Science<\/span><\/h3>\n<ul dir=\"ltr\" style=\"text-align: left\">\n<li><span style=\"vertical-align: inherit\">Publisher:&nbsp;
