Sobre o curso

In this course you will be introduced to two methods of writing SQL queries that retrieve data from two or more tables. Since one of the functions of a database is to store data in an organized format, many databases are made up of multiple tables. Often, the data output required from the database is made up of data from more than one table. For example, the data that populates a student transcript might come from the Student, Course, and Section tables. While the Student table may provide the student’s name, the name and number of the course might come from the Course table and the specific grade for that course may come from yet another table. While writing SQL queries in SQLiteStudio, you'll learn the SQL syntax required to join tables together as you develop an understanding of how the relationships among tables come into play. 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....

T​he quality of this course is very good. But the content is half of the normal coursera projects. The instructor could combine two of her courses into just one. For example, this course could be easily combined with 'Retrieve Data with Single-Table SQL Queries' in order to build a single course with normal time duration/length less than 2 hours.
