Description

Become an expert in SQL and PostgreSQL with this bestselling course!SQL is one of the most in-demand tech skills across many industries so learning SQL is one of the best ways to boost your career! After taking this course you will be comfortable putting SQL and PostgreSQL on your resume/CV. In the age of Big Data and Data Analysis, demand for employees with SQL skills has never been higher and will only increase in the future. Stand out from the crowd and learn SQL today. PostgreSQL is the World’s most advanced open source relational database. It has a strong reputation for its reliability, data integrity and robustness. Because of this, PostgreSQL is one of the most popular and widely used database systems in the world. Companies who use PostgreSQL include Apple, Cisco, Spotify, Fujitsu, Skype, Netflix and IMDb. A 2019 survey of stackoverflow developers reported that one third of developers used PostgreSQL on a daily basis in their professional lives, up from 25% in 2018. In 2019 PostgreSQL was the fastest growing database for the third year in a row. PostgreSQL experience really is a desired skill in the tech industry. Here's what students are saying about this SQL course: Christopher says - "A really great course. The structure was well setup and the pacing was perfect. Each section and lecture flowed well in to the next. The exercises and solutions were very helpful. I was new to sql and postgresql before taking this course but I can now say that I am comfortable with both." Erin Todd says - "I love this course so far very easy to follow and interactive."Raymond Beauchamp says - "Amount of information is good for a beginner course. Was beneficial in increasing my understanding of the subject. Instructor was knowledgeable, and was easy to follow." John Hellmann says - "Very concise lectures! Was a great course overall"Abhinav Sharma says - "The explanations are really clear and the course structure is very well thought out."By the end of this course you will know how to:Create a relational database from scratchCreate, alter and delete tables from a databaseInsert, update and delete data from a table Retrieve data from a database using select queriesFilter data using where clauses and logical operators Order and limit data retrieved from a tableUse aggregate functions and group data to gain more meaningful insights from a databaseRelate tables together using database relationshipsUse SQL join queries to retrieve data from multiple tables in a single queryMaster complex SQL subqueriesApply SQL string functions to data in PostgreSQL

A step-by-step video of how to install and setup PostgreSQL is included and the setup is completely FREE.The SQL code for each video is included as a resource so you can easily access it. There are SQL exercises, and video solutions, along the way to help you improve your knowledge and SQL skills.  I will be actively answering any questions you may have about the course in the Q&A section. The course will be continually updated with more sections in the future.
