Описание: This book establishes a good learning mechanism by initially covering simple topics such as Heroku Toolbelt before moving on to complex topics such as data caching and tuning and PostGIS.
The book begins by giving you an introduction to the working of Heroku Postgres. This is followed by an overview of the PostgreSQL add-on, using which you'll create your first database and connect it using various programming languages such as Java, Ruby, Python, and Node.js. You will then look at securing your data, monitoring, working with permissions, and generating backups along with database rollbacks, followers, and forks to manage any loss in your data. Finally, you will improve the performance of your database by diving into log statements and understand how to avoid common mistakes.
