What is PostgreSQL?
Learn about PostgreSQL, its vital use cases, and some pros and cons.
We'll cover the following...
Introduction to PostgreSQL
PostgreSQL is a powerful, open-source object-relational database system. It was first released in 1986, and since then, it has remained one of the most advanced database management systems. A strong developer community has actively maintained it for over 30 years. It’s known for its reliability, feature robustness, and performance. It’s available under the terms of the PostgreSQL License, a liberal open-source license.
PostgreSQL, being an object-relational database, can store data in objects. This allows data to be related to each other through relationships between objects rather than just through common fields. It supports both SQL for relational data and JSON for non-relational data. PostgreSQL is ACID compliant, meaning it supports transactions and maintains data integrity.
PostgreSQL is a powerful database system well-suited for OLTP and OLAP applications. It’s easy to use and has many features that make it a good choice for various applications.
Online transaction processing
Online transaction processing (OLTP) is a type of database processing that deals with transactions, such as data entry and retrieval. We typically use OLTP databases for online applications that require real-time data access, such as e-commerce websites and ATM systems.
Challenges of an OLTP system
OLTP systems can be highly complex, making them difficult to design and implement due to the following challenges:
They must handle a large number of transactions quickly and efficiently.
They must be highly available, meaning they can’t go down for even a short period.
They must be secure to prevent data ...
