In this course you will experience the process of defining, creating, and managing relational database tables using the SQL language. Tables are used as the containers for the data in a database. As such, the structure, or makeup, of each table in a relational database is critical, since it must be designed and created specifically to meet the needs of the data it will contain. The table’s structure indicates which pieces of data are stored in a table, as well as the type and size of each piece of data.
Throughout the course, you’ll be exposed to guidelines and rules that database designers use to make sure that the tables will keep the data as safe and accurate as possible. You’ll learn to use SQL code to incorporate the constraints that help the database management enforce those rules. As you work through and complete hands-on tasks, you’ll become familiar with SQLiteStudio, the database management system used in the course. Tables that are well-designed and created correctly improve data integrity--and make data retrieval easier!
Note: This course works best for learners who are based in the North America region. We’re currently working on providing the same experience in other regions.

Syllabus
- Creating Tables with SQL
- In this course you will experience the process of defining, creating, and managing relational database tables using the SQL language. Tables are used as the containers for the data in a database. As such, the structure, or makeup, of each table in a relational database is critical, since it must be designed and created specifically to meet the needs of the data it will contain. The table’s structure indicates which pieces of data (fields) are stored in a table, as well as the type and size of each field. For example, a Student table would likely contain a student’s ID, which might be a number, and a student’s first and last names, which would be made of letters. Throughout the course, you’ll be exposed to guidelines and rules that database designers use to make sure that the tables will keep that data as safe and accurate as possible. You’ll learn to use SQL code to incorporate the constraints that help the database management enforce those rules. For example, designating one specific field to uniquely identify each row in a table would avoid duplicate rows. Two students with the same student ID could be disastrous for the student who gets both tuition bills! As you work through and complete hands-on tasks, you’ll become familiar with SQLiteStudio, the database management system used in the course. Tables are the foundation of the relational database. When they are well-designed and created correctly, they do their jobs well by improving data integrity--and making data retrieval easier!
