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

Chapter 11. Using Java in PostgreSQL

In the previous chapter, we talked about how to make a connection to PostgreSQL using PHP; the available PHP functions to modify the database objects using DMLs and DDLs; and functions to fetch the data using SELECTs. To understand this better, we even provided examples. This gives you a basic idea about how to proceed with PHP if you want to build code based on it. In this chapter, we will make database connections using Java, which is one of the most popular programming languages in the technology world. Additionally, we will also cover how to create objects using Java, and how to manipulate data once the objects are created. We will provide some examples with sample codes, which will help you start with it. We will also talk about Java Database Connectivity (JDBC) drivers that are needed to run the Java code against databases.
