PostgreSQL is an open-source relational database management system developed by a worldwide team of volunteers. No single corporation or private entity controls PostgreSQL and its source code is available free of charge.<\/p>\n\n\n\n

PostgreSQL is one of the oldest relational database management systems, with its first version dating back to 1997. A relational database management system facilitates storage of data in the form of inter-related tables. PostgreSQL has turned out to be a very reliable solution, owing to the simplicity in maintenance, which can be easily decentralized across multiple data centers. This is why it finds itself with a great chunk of share in modern production databases. And because of its widespread use, knowledge in PostgreSQL is a must skill to have. Let’s take a look at the various resources that are available to help learn PostgreSQL.<\/p>\n\n\n\n

What is PostgreSQL?<\/h3>\n\n\n\n

PostgreSQL was first released as the Ingres project in 1981 at the University of California. Its name was later changed to Postgres, as it was released after the Ingres project, therefore it became \u201cpost-Ingres\u201d. In 1996, the website PostgreSQL.org was launched, which marked two things \u2014 new support for the SQL standard as well as the online presence of the solution.<\/p>\n\n\n\n

The first release of the official \u201cPostgreSQL\u201d was made in 1997. Since then, the database system has been continuously developed and improved. The PostgreSQL global development group handles the maintenance of the solution to this date, and new releases are quite frequent.<\/p>\n\n\n\n

PostgreSQL offers exceptional performance in terms of a database management solution. It is a highly stable database management system, backed by more than 20 years of community development. It has a rich history for support of advanced data types, and it supports a level of performance optimization that is common across its commercial counterparts like Oracle and SQL Server.<\/p>\n\n\n\n

What is PostgreSQL used for?<\/h3>\n\n\n\n

PostgreSQL has grown to become a popular choice when provisioning remote databases. Before we set down to learn the tool, let\u2019s explore some of its use cases:<\/p>\n\n\n\n

General Purpose Database<\/h4>\n\n\n\n

PostgreSQL can handle general functions quite well. Start-ups and large enterprises prefer using PostgreSQL as their primary data storage solution. PostgreSQL has great support for real-time operations, as well as scales pretty well when used in production environments.<\/p>\n\n\n\n

LAPP Open Source Stack<\/h4>\n\n\n\n

LAMP stack (Linux, Apache, MySQL, and PHP\/Python\/Perl) has been a very popular stack over the years. With the introduction of PostgreSQL, a new variant called LAPP (Linux, Apache, PostgreSQL, and PHP\/Python\/Perl) has been introduced. This helps create reliable, dynamic websites faster.<\/p>\n\n\n\n

Geospatial database<\/h4>\n\n\n\n

PostgreSQL supports an extension called PostGIS. With PostGIS, geographical objects can be stored easily, and the database can be used as a geospatial data store for location-based services and geographic information systems (GIS). <\/p>\n\n\n\n

This means that with PostgreSQL,you can easily create databases that store location-related data. This can support apps that allow real-time location sharing, or those that use location as an important object in their business logic. Not many database management solutions support location-based data storage, and out of all those that do, PostgreSQL comes out on top.<\/p>\n\n\n\n

Federated Hub Database<\/h4>\n\n\n\n

PostgreSQL works great with other database management solutions. Features like Foreign Data Wrappers and JSON support allow it to link with other data stores and act as a federal hub for multi-language database systems.<\/p>\n\n\n\n

Scientific Data Handling<\/h4>\n\n\n\n

Scientific data requires processing terabytes of data to infer results. Storing data of this scale is an extensive task in itself. PostgreSQL has proved itself over the years as a reliable, robust solution for storing such a large amount of data, and hence is the perfect fit for this scenario.<\/p>\n\n\n\n

Learning PostgreSQL<\/h2>\n\n\n\n

Given that PostgreSQL is a robust database management solution, it is important to have it as one of your primary skills if you are planning to become a LAMP\/LAPP stack developer. Following is a list of resources to help you get started.<\/p>\n\n\n\n

The Best PostgreSQL Resources<\/h3>\n\n\n\n

As PostgreSQL is an open-source tool, a lot of people have tried to create content that can help you easily get started. First of all, let\u2019s take a look at the free and paid video courses that are available for PostgreSQL:<\/p>\n\n\n\n
