There are numerous databases that use relational management (RDBMSs) to pick from, depending on which model best fits your data. PostgreSQL is among the most well-known and highly regarded open-source relational databases around the world.
This article will provide a brief overview of the most important reasons that make many developers select PostgreSQL for their needs in managing data. They range from availability of features and standards conformity to communities support, as well as management.
Robust feature set
One of the major reasons to select PostgreSQL is the extensive list of options. PostgreSQL has an impressive array of functions related to performance security, security, programming extensions and configuration, among other things.
Some of the features PostgreSQL provides include:
Support for the writing of database functions with:
SQL
Tcl
Perl
Python
Java
Lua
R
Shell
Javascript
Support for a variety of data types like:
commonly used database primitives, such as numeric string, boolean and datetime types are used in the majority of databases and offer great support in PostgreSQL.
address for networks: PostgreSQL supports various network-related kinds like CIDR addresses and subnet masks and MAC addresses both for IPv4 as well as IPv6.
Geometric types: A range of shapes are available to help identify two-dimensional objects. These include lines, points and segments and even complete shapes such as polygons, boxes and circles.
Types of money: The PostgreSQL money type stores currency with the fixed precision of fractions. It is a type that is locale-aware and has automatic formatting for output.
ranges: They allow users to work with natively the range of values dates and time ranges to schedule.
JSONB PostgreSQL’s native support for operating and storing JSON objects will allow you to use both non-relational as well as relational data in the same platform.
Hstore: This type lets you use key-value pairs in a native way.
arrays that are multidimensional: Arrays can be excellent to store multi-part values which aren’t very meaningful outside of their particular context.
Possibility to design your own complicated types: Define your own types can help you better align your database to the way that your data is presented in your software.
Full-text search: Full-text searching provides you with powerful methods to locate and operate on information in semi- or unstructured text. Search can be tuned to ensure relevance and matching.
Access control, robust authentication and management of privileges systems are ideal for companies regardless of dimensions: PostgreSQL has mature user authorization and authentication capabilities to identify who can access the system, and what information each user is permitted to view or perform.
Foreign data wrappers Foreign data wrappers allow to access tables and data on remote servers.
Views and materialized views Views and materialized views allows for easy access to data through abstracting table structures to provide information that is often searched for.
Comments on objects in databases The ability to include comments on databases, tables columns, tables, as well as other database objects lets you make notes on decisions or the details of implementation.
Write-Ahead Logging that provides point-in-time recovery along with failover and streaming replication. These techniques make sure that the database stays constant even when the software is damaged, and help transfer data between systems to increase the capacity and back up your data.
Support for NoSQL-like behavior , such as storing documents with JSONB or key value pairs using hstore: Being able to work with multiple database paradigms in one system can help reduce the administrative burden and enhance compatibility between the various representations.

Object-oriented database features
One of the main ways in which PostgreSQL differs from other databases based on relationality is due to its fundamental design.
The majority of relational databases can be identified by the term Relational Database Management Systems (RDBMSs). RDBMSs are specifically designed software to manage relational databases, which store data in tables-like structures, with predefined columns as well as data types. Data can be accessed or modified, as well as retrievable using methods built on relational algebra, generally via the structured query language (SQL).
PostgreSQL On its own actually is the same as an Object-Relational Database Management System (ORDBMS). This means it is able to perform the same functions as an RDBMS however it offers some features that are object-oriented.
Practically this implies that PostgreSQL permits you to:
Make your own complicated data types
Overload functions that use different arguments data types
Define the inheritance relationships between tables
These tools are powerful that allow you to manage your databases and data by using the same methods you’ve used when you program. The greater flexibility allows you to define different types of relations within the system, instead of externally in your applications. This will help ensure uniformity and make sure that the behavior you want to enforce is more closely in relation to actual information.
SQL standards conformity
Another aspect where PostgreSQL distinguishes itself from other database systems that use relational databases is its compliance with SQL standards.
SQL standards have been created in collaboration with ANSI as well as ISO groups with the aim of defining minimum functionality as well as interoperability specifications to SQL implementations. While the specifications issued by these organizations are intended to outline the features SQL systems must provide because of the complexity and the long-term evolution of the language strict conformity isn’t always feasible. In accordance with the PostgreSQL document, there is no database that currently meets the requirements set out in the specification.
In light of that, PostgreSQL satisfies more of the SQL specifications than the other options. Based on their own estimates they are in compliance with at least 160 of the 179 essential specifications set out by SQL:2016.
ACID compliance
ACID is an abbreviation in computer science. It is a reference to atomicity, stability isolation, durability and. These are the fundamental guarantees that database transactions have to support to prevent validity errors and to ensure integrity of data.
ACID compliance is a major issue for relational databases since it reflects the standard expectations for the storage and modification of extremely structured information. Non-relational databases typically try to adhere to their own standards, which is often depicted by the BASE in the form of generally open, soft state and ultimately, the sameness.
While most database systems strive to offer ACID compatibility, PostgreSQL has boasted ACID-compliance within its engine since. Because PostgreSQL utilizes on a single database engine it implies every transaction is ACID conforming by default. This is done without database locks that are secured by the multiversion concurrency controller (MVCC). In contrast, MySQL only supports full ACID compliance when you use its InnoDB or NDB databases. This could lead to unexpected corruption when other engines are utilized.
Community and open-source development
PostgreSQL is an open-source software project run by the PostgreSQL Global Development Group. It is licensed under The PostgreSQL License, a license that is recognized through The Open Source Initiative.
There are numerous database systems that are open source, PostgreSQL is developed and operated without the help of a corporation or commercial counterpart. This allows the contributors to chart their own course and work on features that the community is concerned for the most. Professional services related to PostgreSQL are offered by businesses who often support the project, but they do not manage the development process.
This emphasis on development driven by the community has brought about a significant participation from the PostgreSQL’s users. There are a variety of top-quality extensions and apps are available to improve the capabilities of the basic PostgreSQL software. Community-developed software will help you manage and manage your PostgreSQL servers, build data for business intelligence, control new kinds of data and also work with PostgreSQL using a variety of programming platforms and languages.
Conclusion
PostgreSQL has built a solid reputation for being a robust multi-featured choice for data in relational format. In terms of stability, performance and standard conformance, PostgreSQL checks all of the right boxes for numerous projects. In addition, if you need flexibility in how you display data and utilize various programs and programming languages, PostgreSQL is also a suitable option.
PostgreSQL is known for its an excellent implementation of the core functions of relational databases without restricting it to the limitations of the traditional RDBMSs. Although no database is able to meet all needs, PostgreSQL is an excellent choice that is flexible enough to accommodate a wide range of needs.
