Descrição do Curso

Learn How the PostgreSQL Create Database Function Works

Have you ever wanted to create and manage your own databases but thought such knowledge is reserved for database administrators? This course teaches you the skills and knowledge necessary create your databases and effectively manage them yourself. You'll cover the structure of PostgreSQL databases, PostgreSQL datatypes, and the normalization of databases to remove data duplication, increase data consistency and improve data organization.

Discover the Structure of PostgreSQL Databases and Learn PostgreSQL Data Types

You’ll start this course by exploring the fundamentals of creating a Postgres database by covering databases, tables, and schemas, understanding how each fits into the PostgreSQL object hierarchy. Next, you’ll look at PostgreSQL data types, including text, numeric, temporal, and boolean data. You’ll also learn the appropriate times to use each data type. As you progress, you’ll learn about database normalization, understanding how it maintains the integrity of your data and reduces duplication. Finally, you’ll cover PostgreSQL access control and how you can protect your databases from unauthorized access.

Create Your Own Database Using PSQL

As you master the skills to create a PostgreSQL database, you’ll work with real data from the U.S. Small Business Administration (SBA) to guide you through the lessons and provide context for the concepts covered in the course. By the time you've completed this PostgreSQL training, you’ll be able to confidently create your own databases using PostgreSQL. "

    Access Control in PostgreSQL

    In this chapter, the topic of access control in PostgreSQL is introduced. Access control is presented as granting and revoking privileges to users and groups on database objects. Using these tools, a database and its objects can be protected from unauthorized access, helping to ensure the integrity of the stored data.
