The vast majority of applications that use data, are backed by a good relational database system. This course will help to establish a base to those who want to begin learning Structured Query Language (SQL).
Structured Query Language (SQL) is a special purpose language for interacting with relational databases. In this course, Introduction to SQL (Update), you will learn the basics of Structured Query Language. First, you will learn how to query data and shape results. Next, you will focus on creating and modifying data in your tables. Finally, you will touch on how actually modify the tables themselves. By the end of this course, you'll understand the basics of how to create and use a relational database.
Is SQL easy to learn?
SQL is relatively easy to learn. It's a query language, not a programming language, and it is English-like, so it's fairly easy to understand and write SQL query. Most database engines are compatible with all SQL code.
Is SQL harder than Python?
Opinions will probably vary here. As a whole language, SQL is definitely simpler than Python. The syntax is intuitive, there is less grammar, and there are fewer different concepts to learn. But as a comprehensive tool, SQL may actually be more difficult than Python coding.
Is SQL a programming language?
While it has the functionality of a mature programming language, SQL is not considered a "programming" language. SQL stands for Structured Query Language. It is a language that allows us to query, insert, update, and modify data in relational databases.
Are there prerequisites to this course?
This is a beginner level SQL tutorial, so no prior SQL experience is required. But it would help to be somewhat familiar with the basic concepts of computer programming.
What concepts will I learn in this course?
You will learn:
Basic SQL syntax
How to query data with the SELECT statement
How to filter results with the WHERE clause
How to shape results with ORDER BY and GROUP BY
How to match different data tables with JOINs
How to add, change, and remove data
How to create database tables
Who should take this course?
This course is for anyone who is interested in data science and learning how to manipulate data. If you work with large sets of data on a regular basis, SQL can greatly improve your understanding of that data, and greatly improve efficiencies.
What is a relational database?
A relational database is just what it sounds like: it is multiple sets of data with a well-defined relationship between the tables in those sets of data. Relational databases allow tables to commnicate and share information across these multiple data sets, which helps with data searchability and organization.

Course Overview [Autogenerated] everyone. My name is John Flanders and welcome to my course introduction to SP one. I'm a developer with over 20 years of experience using relational databases. And despite the fact that topics like big Data and no sequel databases get all the press these days, the vast majority of applications that use data which, by the way for the vast majority of application are backed by a good old fashioned relational database system. His program, using structured query language, also known as sq, This course will provide you with the basics that you need to know to get started using SQL. No prior SQL experience is required. Some of the major topics that we will cover include terrain data using the select statement, shaping your results, using the wear, clogs, creating and modifying data in your tables, as well as creating and modifying those tables themselves. By the end of this course, you'll know the basics of how to create and use a relational database. Before beginning the course, you really only need to be familiar with the basic concepts of computer program. I hope you'll join me here.
