Overview of this book

PostgreSQL is an open source database used for handling large datasets (Big Data) and as a JSON document database. It also has applications in the software and web domains. This book will enable you to build better PostgreSQL applications and administer databases more efficiently. We begin by explaining the advanced database design concepts in PostgreSQL 9.6, along with indexing and query optimization. You will also see how to work with event triggers and perform concurrent transactions and table partitioning, along with exploring SQL and server tuning. We will walk you through implementing advanced administrative tasks such as server maintenance and monitoring, replication, recovery and high availability, and much more. You will understand the common and not-so-common troubleshooting problems and how you can overcome them. By the end of this book, you will have an expert-level command of the advanced database functionalities and will be able to implement advanced administrative tasks with PostgreSQL.

PostgreSQL Overview

Summary

In this chapter, you learned about the advanced features provided by SQL. On top of simple aggregates PostgreSQL provides ordered sets, grouping sets, windowing functions, recursions, as well as an interface to create custom aggregates. The advantage of running aggregations in the database is that code is easy to write and a database engine will usually have an edge when it comes to efficiency.

In the next chapter, we will turn our attention to more administrative tasks such as handling log files, understanding system statistics, and implementing monitoring.
