There are a variety of RDBMSs (RDBMSs) to select from, if the model you choose best fits your data. PostgreSQL is among the most well-known and highly regarded open-source relational databases available in the world.
This article will discuss some of the most important reasons that make many developers select PostgreSQL for their data management requirements. This includes everything from features’ availability and standards conformity to communities support, as well as administration.
Robust feature set
One of the major reasons to select PostgreSQL is its extensive array of options. PostgreSQL offers an amazing array of functions related to performance security, extension of programming, security and configuration, among others.
Some of the features PostgreSQL client includes are:
Support for the writing of database functions with:
SQL
Tcl
Perl
Python
Java
Lua
R
Shell
Javascript
Support for a wide range of data types like:
commonly used database primitives, such as numeric string, boolean and datetime types are present in all databases and offer great support in PostgreSQL.
Network addresses: PostgreSQL supports various network-related types , such as CIDR addresses and subnet masks and MAC addresses both for IPv4 as well as IPv6.
Geometric types: A range of shapes can be used to create two-dimensional objects. These include lines, points and segments as well as shapes that are complete such as polygons, boxes and circles.
Money types: PostgreSQL’s 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 different values in a range, such as dates, for instance, and time ranges to schedule.
JSONB The native support of PostgreSQL to store and operate on JSON objects allows you to use both non-relational and relational data on the same platform.
Hstore: The hstore type lets you utilize key-value pairs in a native way.
arrays that are multidimensional: Arrays can be extremely useful to store values with multiple parts that aren’t much of a value outside of their particular context.
Possibility to design your own complicated types: defining your own types allows you to better align your database to the way that your data is displayed in your software.
Full-text Search: Full-text search provides you with powerful methods to locate and operate on information in semi- or unstructured text. Search can be tuned to meet your expectations of relevance and match.
Secure authentication, access control and access control 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 enable to create tables and to access tables and other data on remote servers.
Views and materialized views Views and materialized views provides easy access to information by abstracting table structures to provide information that is often searched for.
Comments on objects in databases The ability to include comments to tables, databases columns, tables, as well as other database objects lets you make notes on decisions or the details of implementation.
Write-Ahead Logging for point-in time recovery along with failover and streaming replication. technology help to keep your data stays constant even when the software fails, and also helps transfer data between systems to increase the capacity and back up your data.
Support for NoSQL-like behavior , such as the ability to store documents using JSONB as well as key value pair using hstore: Being able to work with different database paradigms within the same system can reduce the administrative burden and enhance compatibility between the various representations.
Object-oriented database features
One of the primary ways in which PostgreSQL is distinct from other databases based on relationality is due to its fundamental design.
Most relational databases are identified by the term Relational Database Management Systems (RDBMSs). RDBMSs are specially designed software to manage relational databases, which are where data is stored in tables-like structures, with predefined columns and types. Data can be accessed or modified, as well as obtained using methods that are built on relational algebra, typically using the structured query language (SQL).
PostgreSQL is, 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 also includes some features that are object-oriented.
Practically in terms of usage, this signifies that PostgreSQL permits you to:
Make your own complicated data types
Overload functions that be able to work with various arguments data types
Define the inheritance relationships between tables
These tools are extremely powerful which allow you to work with your data and databases using similar techniques you’ve used when writing programs. The more flexible approach lets you create different types of connections within your database rather than externally in your applications. This will help ensure the consistency and ensure that your intended behavior is close in relation to actual information.
SQL standards conformity
Another aspect where PostgreSQL is distinct from other database systems that use relational databases is its compliance with SQL standards.
SQL standards have been created through ANSI as well as ISO groups in the hopes of defining minimum functionality as well as interoperability specifications in SQL implementations. Although the specifications offered by these organizations are intended to outline the features SQL systems should offer due to 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 specifications outlined in the specification.
With that caveat, PostgreSQL satisfies more of the SQL specifications than the other options. According to their own calculations they are in compliance with at least 160 of the 179 specifications laid out in SQL:2016.
ACID compliance
ACID is an abbreviation in computer science. It refers to atomicity and coherence isolation, durability and. ACID is the most important guarantee that transactions in databases must provide to prevent validity issues and ensure data integrity.
ACID compliance is a major concern for databases that use relational databases because it is the norm to store and modify extremely structured information. Non-relational databases usually try to adhere to their own standards, which is often depicted by the BASE acronym, which means generally open, soft state and eventually, the sameness.
Although nearly all databases in the world strive to have ACID compatibility, PostgreSQL has boasted ACID-compliance within its engine since. Because PostgreSQL utilizes on a single engine for database, it implies every transaction is ACID conforming by default. This is done without database locks that are secured by Multiversion Concurrency Control (MVCC). For contrast, MySQL only supports full ACID compliance when you use its InnoDB or NDB databases, which could lead to unexpected corruption when other engines are employed.
Community development and Open Source development
PostgreSQL is an open-source software project that is managed by the PostgreSQL Global Development Group. It is licensed with The PostgreSQL License, a license that is recognized through The Open Source Initiative.
There are numerous free relational databases available, 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 aspects that the community cares regarding the greatest. Professional services offered by PostgreSQL are offered by companies who often support the project, but don’t have control over the development process.
This emphasis on development driven by the community has led to a huge participation from the PostgreSQL’s users. Many premium extensions and programs are available to improve the capabilities of the basic PostgreSQL software. Software developed by community members will assist you in managing the administration of your PostgreSQL servers, create data for business intelligence, handle new kinds of data and integrate with PostgreSQL using a variety of programming platforms and languages.
Conclusion
PostgreSQL has earned a prestigious 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 present data and utilize various programs and programming languages, PostgreSQL is also a suitable option.
PostgreSQL is renowned for its an excellent implementation of the core features of a relational database without limiting it to the limitations of the traditional RDBMSs. Although no database is able to meet all needs, PostgreSQL is an excellent alternative that can be adapted to meet the needs of a variety of applications.
