PostgreSQL in Action

PostgreSQL (pronounced Post-Gres-Q-L) or postgres for short is an open source object relational database management system. It emphasizes extensibility and creativity as well as compatibility. It competes with the major relational database vendors such as Oracle, MySQL, SQL servers, and others. It is used by different sectors including government agencies and the public and private sectors. It is a cross-platform DBMS, and runs on most modern operating systems including Windows, macOS, and Linux flavors. It conforms to SQL and is ACID-compliant.

In this chapter, we will explore several topics including:

PostgreSQL history.
Selected PostgreSQL forks.
Companies utilizing PostgreSQL and success stories
PostgreSQL usage pattern.
PostgreSQL architecture, capabilities and features.
PostgreSQL installation on Linux as well as windows.
PostgreSQL client...

Key benefits

• Be introduced to the concept of relational databases and PostgreSQL, one of the fastest growing open source databases in the world

• Learn client-side and server-side programming in PostgreSQL, and how to administer PostgreSQL databases

• Discover tips on implementing efficient database solutions with PostgreSQL 10

Description

PostgreSQL is one of the most popular open source databases in the world, supporting the most advanced features included in SQL standards. This book will familiarize you with the latest features released in PostgreSQL 10. We’ll start with a thorough introduction to PostgreSQL and the new features introduced in PostgreSQL 10. We’ll cover the Data Definition Language (DDL) with an emphasis on PostgreSQL, and the common DDL commands supported by ANSI SQL. You’ll learn to create tables, define integrity constraints, build indexes, and set up views and other schema objects. Moving on, we’ll cover the concepts of Data Manipulation Language (DML) and PostgreSQL server-side programming capabilities using PL/pgSQL. We’ll also explore the NoSQL capabilities of PostgreSQL and connect to your PostgreSQL database to manipulate data objects. By the end of this book, you’ll have a thorough understanding of the basics of PostgreSQL 10 and will have the necessary skills to build efficient database solutions.

Great for explaining posgreSQL for a beginner

PK Feb 27, 2019

As with all Packt Publishing books, this is rough. The index is useless (it doesn't even include obvious words such as 'varchar'), so the book isn't useful as a reference. It *might* be of some value to somebody who already knows quite a bit of Postgres, and who wants yet another book full of tips.It's certainly not appropriate for a learner. Obscure commands are introduced before the basics have been explained. Code is thrown in without explanation. Concepts are explained badly, in broken English. Even the diagrams look like a rough draft. And, like all Packt Books, there's at least one typo in every paragraph.Why does Packt claim to have technical editors and proof-readers, when they are so obviously incompetent? Why does the indexer even want her name printed in the book? I would be ashamed to have been responsible for a book like this. (Although, to be fair, her name, Rehka, is appropriate.)Packt goes for volume rather than quality. I have six Packt books on Postgres, most of which are valueless. They are produced in India, presumably for a much less demanding market, using the cheapest editors they can find in the back-streets. What is particularly galling is the dishonest claim at the beginning of the book that 'quality is at the heart of our editorial process'. You don't get 'quality' from non-native proof-readers, inexperienced indexers and unsupervised first-time authors.

I completely agree with the sentiment of the reviewer with initials PK. This book is way over complicated and is too technical for leaning a new concept. Examples are obscure and don't provide enough simplicity for understanding. Like PK pointed out, the index is a complete after thought, or perhaps, no thought at all. I would give this book zero stars if permitted.

I know it's a 4 year old book and PostgreSQL10 is about the same age but to declare it's a Second Edition is just embarrassing. I'm not sure what was changed but there is no way in the world that editorial changes were made. If you can get through a single page without finding a punctuation misplacement, spelling error, or grammatical mistake, you aren't actually reading this book. The class I'm taking is using this as a textbook and I'll read the code they present but I can't be sure if there's a mistake or I'm just not smart enough to understand the code. It is so poorly written that it is actually preventing me from learning the concepts. Needless to say, avoid this book.
