Overview of this book

PostgreSQL is the most advanced open source database in the world. It is easy to install, configure, and maintain by following the documentation; however, it’s difficult to develop applications using programming languages and design databases accordingly. This book is what you need to get the most out of PostgreSQL You will begin with advanced SQL topics such as views, materialized views, and cursors, and learn about performing data type conversions. You will then perform trigger operations and use trigger functions in PostgreSQL. Next we walk through data modeling, normalization concepts, and the effect of transactions and locking on the database. The next half of the book covers the types of indexes, constrains, and the concepts of table partitioning, as well as the different mechanisms and approaches available to write efficient queries or code. Later, we explore PostgreSQL Extensions and Large Object Support in PostgreSQL. Finally, you will perform database operations in PostgreSQL using PHP and Java. By the end of this book, you will have mastered all the aspects of PostgreSQL development. You will be able to build efficient enterprise-grade applications with PostgreSQL by making use of these concepts

Preface

Summary


In this chapter, we used PHP with Postgres. We started with simple connections; however, we talked about the available PHP functions for DDL, DML and SELECT. For your convenience, we described each section with examples and provided PHP code that you can test yourself. We hope that will give you a better understanding of PHP. We also hope that, after reading this chapter, you will be able to prepare PHP code and execute it on your own. In the next chapter, we will talk about Java with PostgreSQL. Java is one of the most popular programming languages in the market. So many applications are designed on Java and connect to the database. We will use real-time examples to describe how and where it is useful. Additionally, we will also cover how to create a table from PL/Java and access/modify it through the code.
