Job Ready SQL

Learn the most important SQL skills and apply them in your job--quickly and efficiently!

SQL (Structured Query Language) is the modern language that almost every relational database system supports for adding data, retrieving data, and modifying data in a database. Although basic visual tools are available to help end-users input common commands, data scientists, business intelligence analysts, Cloud engineers, Machine Learning programmers, and other professionals routinely need to query a database using SQL.

Job Ready SQL provides you with the foundational skills necessary to work with data of any kind. Offering a straightforward 'learn-by-doing' approach, this concise and highly practical guide teaches you all the basics of SQL so you can apply your knowledge in real-world environments immediately. Throughout the book, each lesson includes clear explanations of key concepts and hands-on exercises that mirror real-world SQL tasks.

• Teaches the basics of SQL database creation and management using easy-to-understand language
• Helps readers develop an understanding of fundamental concepts and more advanced applications such as data engineering and data science
• Discusses the key types of SQL commands, including Data Definition Language (DDL) commands and Data Manipulation Language (DML) commands
• Includes useful reference information on querying SQL-based databases

Job Ready SQL is a must-have resource for students and working professionals looking to quickly get up to speed with SQL and take their relational database skills to the next level.
