Welcome to SQL:
Welcome to SQL. Let’s begin!
SQL stands for Structured Query Language, and it’s a programming language for managing data in relational databases. SQL is based on declarative statements that are simple to understand. This ensures that data is accurate and secure, as well as the integrity of databases of any size.
The SQL programming language now widely uses in web frameworks and database applications. Knowing SQL gives you the freedom to investigate your data and the ability to make more informed decisions. So, you will learn concepts that apply to nearly every data storage system by learning introduction to SQL.
The SQLite Relational Database Management System uses in the statements covered in this course (RDBMS). A glossary of all the SQL commands covered in this introduction to SQL is also available.
Importance of this course:
This course is for anyone who is comfortable with computers and wants to learn how to read and manipulate data stored in a relational database. The abbreviation for Structured Query Language (SQL) can be pronounced in a few different ways: SQL or Sequel. Both are correct; the term “Sequel” is frequently used in reference to the Microsoft Sequel server product, which is the database management tool we’ll be using in this course.
A data scientist’s job is to turn raw data into useful information. Much of the world’s raw data, from electronic medical records to customer transaction histories, is stored in relational databases. To be a successful data scientist, you must be able to manipulate and extract data from databases using the SQL programming language. This course teaches SQL syntax that is common to many databases, including PostgreSQL, MySQL, SQL Server, and Oracle. This course will teach you everything you need to know about databases so you can start working with them right away!
This self-guided course allows you to learn at your own pace. You can meet other students, share your ideas, and participate in active discussions in the comments at any time during the course.
