PostgreSQL, a robust and versatile relational database management system (RDBMS), is gaining immense popularity due to its reliability, scalability, and rich feature set. This book is your indispensable companion to mastering PostgreSQL, helping you become a great PostgreSQL developer and create amazing database-driven applications.
This book provides a thorough introduction to PostgreSQL, covering the fundamentals of database creation and management to advanced topics like data modeling, query optimization, and performance tuning. Explore PostgreSQL’s powerful features, including multi-version concurrency control (MVCC), data types, constraints, and indexing. Learn how to install, configure, and apply PostgreSQL in real-world scenarios. You will also develop essential SQL skills to manipulate and analyze data, design efficient schemas with normalization, and use stored procedures and triggers to automate tasks effectively.
Databases are the backbone of applications. PostgreSQL is a robust, open-source, and widely used relational database management system. It is the preferred option for both database administrators and developers. PostgreSQL has a wide range of sophisticated data types and strong feature sets, which improve the software's extensibility, dependability, and data integrity.
This book will walk you through essential concepts, such as installation, administration, and usage of PostgreSQL, ensuring that both beginners and experienced developers can maximize the potential of this powerful database system. A thorough understanding of PostgreSQL's capabilities is essential for developing secure, effective systems.
By the end of this book, you will have a solid understanding of PostgreSQL's core concepts and best practices. You will be able to create complex database structures, write efficient SQL queries, optimize database performance, and implement robust data management strategies.
Features of PostgreSQL have been listed as follows:
PostgreSQL is open-source and is easily downloadable from its official website without any charge.
It serves as a robust back-end database for dynamic websites and web applications as it has robust datatype, indexing and many rich features.
It is compatible with the most popular programming languages like Python, Java, C#, C/C+, Ruby, jаvascript (Node.js), Perl, Go, Tcl, etc.
Supports procedural languages such as Perl, PL/PGSQL, and Python, etc. You can use Postgres as back-end with Java, Python etc.
It also supports diverse datatypes like JSON, HSTORE, etc.
PostgreSQL implements various SQL features like complex queries, multiple indexing, procedures, triggers, joins, etc.
It features a sophisticated locking mechanism and supports asynchronous replication.
PostgreSQL supports internationalization and is compatible with ANSI-SQL2008.
We can also install several extensions to add additional functionality to PostgreSQL.
The Multi-Version Concurrency Control feature was also first implemented by PostgreSQL.
