About Postgres
|
||
|
|
--------------
|
||
|
|
|
||
|
|
`Postgres (or PostgreSQL) <https://www.postgresql.org/>`__ is a general-purpose object-relational database management system that uses and extends the SQL language.
|
||
|
|
Postgres is free and open source and has been developed continuously over the last 30 years. Postgres strives to be reliable, robust and performant.
|
||
|
|
|
||
|
|
Postgres supports advanced data types and advanced performance optimization, features that are otherwise only available in expensive commercial database systems.
|
||
|
|
|
||
|
|
Benefits of Postgres
|
||
|
|
--------------------
|
||
|
|
|
||
|
|
The following are benefits of Postgres compared to other database management systems:
|
||
|
|
|
||
|
|
- Postgres can be maintained easily because of its stability. The total cost of ownership is therefore low.
|
||
|
|
- Postgres is designed to be extensible i.e. you can add custom functions using different programming languages.
|
||
|
|
- You can define your own data types, index types etc.
|
||
|
|
- If you need any support, an `active community <https://www.postgresql.org/community/>`__ is available to help.
|
||
|
