PostgreSQL is a powerful and advanced open-source enterprise-class database known to support JSON (non-relational) and SQL (relational) querying. The database is very stable, it has been around for more than twenty years, and a good reason it has a high level of correctness, integrity, and resilience. The database is used by many mobiles, analytical, web, and geospatial applications as primary storage for their data. The latest invention in this database is PostgreSQL 12.

PostgreSQL is known for supporting powerful data types; it also supports performance optimization just like its counterparts. PostgreSQL can run on all main operating systems. Since 2001 the program has been an acid complaint. Currently, DBA is one of the preferred choices for many individuals and companies.

What is PostgreSQL Database

The project started back in 1986 under Prof. Michael Stonebreaker who was lecturing at the University of California. At first, the company was known as Postgres, this to refer to a former project developed at the same place. Postgres at that time wanted to add some features that were missing to support different data types. Postgres was later named PostgresSQL in order to show support to SQL language. We can refer to PostgreSQL as Postgres (an abbreviation of PostgreSQL) the development group is known to release minor and major releases of this open and free database.

The project is never easy for beginners. Make sure you select the project you need to create and let the DBA robustly and safely store the data.

What is PostgreSQL Used For

The database has many features whose aims are assisting developers create applications, the administrators in protecting the data, and built a conducive environment, it helps in managing the data no matter the size. Apart from being an open and free source, the dba is extensible, this means defining the data type is easy, and you can customize different functions and use different coding language without tampering with the database.

Below is a list of various features you will find on this database:

Data types

Primitive: Boolean, integer, string, Numeric
Structured: UUID, Range, Array, Date/Time
Document: key-value(Hstore), XML, JSONB?JSON
Geometry: polygon, circle, line, point
Customizations: custom types, composite

Data integrity

NOT NULL, UNIQUE
Primary keys
Advisory locks, Explicit locks
Exclusion Constraints
Foreign Keys

Concurrency Performance

Indexing: partial, Expression, multicolumn, B-tree
Optimizer, multicolumn statistics, Index-only scan.
Multi-version concurrency function
Creating B-tree indexes

Table partitioning

Disaster recovery, reliability
Replication: logical, synchronous, asynchronous
Tablespace
Write-ahead logging

Security

Authentication: Certificate, SCRAM-SHA-256, LDAP, SSPI, GSSAPI
Row-level security and column

Extensibility

Procedures and stored functions
Procedural language: python, Perl, PL/PGSQL
JSON/SQL Path expressions
Interface

Large and starter enterprises prefer using PostgreSQL as the main storage for data in order to support internet solutions, products, and applications use it for:

Geospacial database

When you use the DBA with other extensions such as PostGesis it can support the use of geographic objects and you can use it for storage of objects in different locations as well as gaining geographic information.

Federated hub database

JSON and other database data wrappers enable it to link with various data stores globally.

LAPP open and free source

The database is known to run dynamic apps and websites as one of the ways to boost the LAMP stack.

Industrial Applications of PostreSQL

The government and the community prefer this method to store GEO data and also in areas such as:

Manufacturing

The companies have adapted this DBA to speed up the data processes in the business. it aids in optimizing the supply chain in that the database can be used as a backup for the data. It will also aid in reducing the operation cost for the companies.

NoSQL and Web technology

If the company is in need of handling thousands of requests per minute, you will be affected by scalability. In this, case postgre is the solution.

The database works well with the current web frameworks such as Node.js, Python, Golang(read more), PHP(read more), and many more. You use replication services where you can handle large data in no time and with ease.

Scientific Data

If you are working on a scientific or research project you are required to generate large terabytes. However, It essential to handle the project in the most effective way. The database will help you manage the data easily.

Creating a cookbook

A cookbook is a collection of instructions, information, and recipe on how you can prepare various meals.

You can use the DBA to create a cookbook with a lot of data as you may wish.
