Finally, you’ll explore the basic structure of databases and discover the different types of keys they use.

In this module, you’ll explore CRUD, or Create, Read Update and Delete operations. You’ll begin with an exploration of SQL data types and learn how to differentiate between numeric data, string data and default values. You’ll also embark upon several exercises in which you’ll learn how to utilize these different data types within your database projects. You’ll then move on to learn how to Create and Read data within a database. You’ll discover how to create databases and tables and populate them with data using SQL statements. Lastly, you’ll explore the SQL statements used for updating and deleting data in a database. And to demonstrate your ability with CRUD operations, you’ll complete exercises that will task you with creating and managing data.

In this module, you’ll explore SQL operators and learn how to sort and filter data. You’ll begin this module with a lesson on SQL operators. As part of this first lesson, you’ll explore the syntax and process steps used to deploy SQL arithmetic and comparison operators within a database. Next, you’ll discover how to sort and filter data using clauses. The clauses that you’ll learn about include the Order By clause, Where clause and Select Distinct clause. In each lesson item, you’ll receive an overview of how each clause is used to sort and filter data in a database. You’ll also view demonstrations of these clauses and then receive an opportunity to try them for yourself.
