Learn PostgreSQL

PostgreSQL is one of the fastest-growing open source object-relational database management systems (DBMS) in the world. As well as being easy to use it's scalable and highly efficient. In this book you'll explore PostgreSQL 12 and 13 and learn how to build database solutions using it. Complete with hands-on tutorials this guide will teach you how to achieve the right database design required for a reliable environment. You'll learn how to install and configure a PostgreSQL server and even manage users and connections. The book then progresses to key concepts of relational databases before taking you through the Data Definition Language (DDL) and commonly used DDL commands. To build on your skills you'll understand how to interact with the live cluster create database objects and use tools to connect to the live cluster. You'll then get to grips with creating tables building indexes and designing your database schema. Later you'll explore the Data Manipulation Language (DML) and server-side programming capabilities of PostgreSQL using PL/pgSQL before learning how to monitor test and troubleshoot your database application to ensure high-performance and reliability. By the end of this book you'll be well-versed with the Postgres database and be able to set up your own PostgreSQL instance and use it to build robust solutions.
