Overview of this book

PostgreSQL is an open-source object-relational database management system (DBMS) that provides enterprise-level services, including high performance and scalability. This book is a collection of unique projects providing you with a wealth of information relating to administering, monitoring, and testing PostgreSQL. The focus of each project is on both the development and the administrative aspects of PostgreSQL. Starting by exploring development aspects such as database design and its implementation, you’ll then cover PostgreSQL administration by understanding PostgreSQL architecture, PostgreSQL performance, and high-availability clusters. Various PostgreSQL projects are explained through current technologies such as DevOps and cloud platforms using programming languages like Python and Node.js. Later, you’ll get to grips with the well-known database API tool, PostgREST, before learning how to use popular PostgreSQL database testing frameworks. The book is also packed with essential tips and tricks and common patterns for working seamlessly in a production environment. All the chapters will be explained with the help of a real-world case study on a small banking application for managing ATM locations in a city. By the end of this DBMS book, you’ll be proficient in building reliable database solutions as per your organization's needs.

Creating a Django project

In order to create a Django project, we have to autogenerate some code that establishes a Django project that is a collection of settings, including the database configurations, Django-specific options, and application-specific settings. Perform the following steps:

  1. We will start by running the following command:
(venv) [root@ip-172-31-95-213 django_app]# django-admin startproject atmproject

The preceding command will create an atmproject directory in your current directory with the following structure:

(venv) [root@ip-172-31-95-213 django_app]# yum install tree -y
(venv) [root@ip-172-31-95-213 django_app]# tree atmproject
