Udemy - SQL and Relational Database Course

Name: Udemy - SQL and Relational Database Course
Author: FreshWap.CC

What you'll learn
Programming with the SQL language
Write SQL queries on a relational database
Create and populate a relational database
Analyze data with SQL
Requirements
Have a PC with a Windows operating system. It is not necessary to have programming experience. You will learn everything you need.
Description
In this course I will explain everything needed to analyze data from a relational database using the SQL language from zero.
You will acquire a skill sought by recruiters in a practical, comfortable and fast way and you will learn how to use a powerful and flexible tool to analyze your data that pushes the boundaries of Excel.
I tried to report in these videos all those teaching methods that I have refined during the thousand and more hours of live teaching. We will start by learning how to write SQL queries to query a database. We will see in particular the operations of filtering, grouping, combining and transforming data, through the well-known SQL statements Select, From, Join, Where, Group By, Having and Order By. We will then study how to create a database from zero, creating the tables and their constraints, finally analyzing the instructions for updating and populating a database, even starting from csv files.
We will use the SQL Server Express Edition database, which I consider the best to use for educational purposes due to its clarity, completeness and rigidity in the syntax. The necessary software can be easily installed on all PCs with a Windows operating system. On the other hand, on Mac and Linux the installation is less immediate, for example it requires the use of Docker and is not covered in the course.
What you DON'T find in the course
slides or power point presentations containing "theory". All the lessons, on the other hand, are accompanied by the relative scripts, full of comments and clarifications. Taken together, they constitute a real SQL manual;
conceptual design;
database administration tasks. The course is aimed at SQL programmers and not DBAs, so there are no topics such as backup, restore, user creation and login;
indexing and performance analysis.
What you find in the course
all you need to learn how to write queries with the main SQL keywords: select, from, join, where, group by, having, order by;
write complex queries with cte and subquery;
create a database from scratch by creating tables with all types of constraints: type, null / not null, primary key, foreign key, check;
populate and update a database, including by acquiring data from .csv files;
all the lessons are accompanied by the relative scripts, full of comments and clarifications. Taken together, they constitute a true SQL manual.
Who this course is for
Anyone who wants to learn the SQL language and approach data analysis
