Learn how to create and query relational databases using SQL in just two hours.
Course Description
Get an Introduction to SQL in Two Hours
Much of the world’s raw data—from electronic medical records to customer transaction histories—lives in organized collections of tables called relational databases. Being able to wrangle and extract data from these databases using SQL is an essential skill within the data industry and in increasing demand.
In just two hours, you’ll get to know the theory and the practice through bite-sized videos and interactive exercises where you can put your new-found skills to the test.
Learn how Relational Databases are Organized
SQL is an essential language for building and maintaining relational databases, which opens the door to a range of careers in the data industry and beyond. You’ll start this course by covering data organization, tables, and best practices for database construction.
Write Your First SQL Queries
The second half of this course looks at creating SQL queries for selecting data that you need from your database. You’ll have the chance to practice your querying skills before moving on to customizing and saving your results.
Understand the Difference Between PostgreSQL and SQL Server
PostgreSQL and SQL Server are two of the most popular SQL flavors. You’ll finish off this course by looking at the differences, benefits, and applications of each. By the end of the course, you’ll have some hands-on experience in learning SQL and the grounding to start applying it to projects or continue your learning in a more specialized direction.
What You’ll Learn
Relational Databases
Before writing any SQL queries, it’s important to understand the underlying data. In this chapter, we’ll discover the role of SQL in creating and querying relational databases. Using a database for a local library, we will explore database and table organization, data types and storage, and best practices for database construction.
Querying
Learn your first SQL keywords for selecting relevant data from database tables! After practicing querying skills in a database of books, you’ll customize query results using aliasing and save them as views so they can be shared. Finally, you’ll explore the differences between SQL flavors and databases such as PostgreSQL and SQL Server.
Introduction to SQL
This introductory SQL training teaches SQL core concepts that can be applied in professional environments. Once students complete this course, they will be able to query and interact with an SQL database, and know how to design database schemas.
Course Description
The Introduction to SQL course introduces a student to common concepts from the application of SQL in professional environments that permits the accurate and effective use of SQL language constructs. Upon completion you will understand how to query and interact with a SQL database, how to write effective queries for use in reporting applications, and how to design simple database schemas for light applications.
Structured Query Language (SQL) is a domain-specific programming language used to manage data that stored in relational database management systems (RDBMS), or to perform stream processing in relational data stream management systems (RDSMS). In other words, SQL is a programming language that is used to interact with a database.
SQL has a long history as a universal coding language and has been used since 1974. It helps programmers transition into learning other computing programming languages such as JavaScript and Python.
Cybrary’s SQL training online is designed to teach students the basics of the SQL language. Students will learn about databases, SQL programming, SQL development, SQL in applications, and how to proceed further in their career paths. The course is online and self-paced. Upon completion, students will understand core concepts related to the application of SQL and will be able to write queries to use in reporting applications and create straightforward database schemas for applications.
SQL is not difficult to learn. It doesn’t require any prior programming experience, which makes it a good place to start. Because SQL is an English-like language, anyone who uses English, even at a basic level, can write SQL queries with ease. In addition, once someone knows SQL, they should be simple to work with any relational databases, as most are compatible with SQL.
SQL is a universal database query language that is widely used. Both novice and experienced IT professionals should become well-versed in SQL. Additionally, this SQL training online is ideal for individuals who are in the following job positions, or who are targeting these positions in the future:
There are numerous reasons to learn SQL, even though there are more modern database languages out there. Here are just a few:
SQL has been around for a long time, and it isn’t going anywhere soon. It’s an essential query language for IT professionals to know, as a starting point to learn other languages like Python and JavaScript.
