This course provides an introduction to querying relational databases. Students will learn the fundamentals of relational databases, including what a relational database is, database normalization, database keys, table relationships, and set operations.
The course begins with an overview of relational databases and their components. Students will learn the basics of database normalization, which is the process of organizing data into tables in order to reduce data redundancy and improve data integrity. They will also learn about database keys, which are used to uniquely identify records in a database table.
Next, students will learn about table relationships, which are the connections between two or more tables in a database. They will learn how to create and manage relationships between tables, as well as how to use set operations to combine data from multiple tables.
Finally, students will learn how to query relational databases using Structured Query Language (SQL). They will learn how to write basic SQL statements to retrieve data from a database, as well as how to use advanced SQL commands to manipulate data.
At the end of the course, students will have a solid understanding of relational databases and how to query them using SQL. They will be able to create and manage relationships between tables, as well as use set operations to combine data from multiple tables. They will also be able to write basic and advanced SQL statements to retrieve and manipulate data from a database.
