This means that PostgreSQL data models can be based on relational database models but can also be object-oriented as well.
PostgreSQL is an object-relational database management system (ORDBMS), instead of a purely RDBMS system like MySQL and MariaDB. With the acquisition of MySQL, Oracle has been a fairly benign steward of the open source project and most of the concerns the community had in the first days of the acquisition have not come to pass, however some open source purists may still prefer MariaDB over MySQL. This means that in most cases third party tools will work across both version and can generally be consider a drop-in replacement for either version. However due to concerns about the future of MySQL after being acquired by Oracle Software, MariaDB was forked from the project as its own entity but maintains its compatible with MySQL client APIs and protocols in addition to data and table definition files. MariaDB and MySQL are binary compatible open source SQL Database servers that originally started as just MySQL. 📘 GET THE GUIDE Examples of SQL Databases MariaDB and MySQL Get the ultimate decision-maker's guide to choosing open source databases, including SQL varieties. Many Fortune 100 companies across several different business sectors including financial, retail, healthcare, and others have turned to these open source alternatives to drastically lower their total cost of ownership when compared to pay-for-play offerings, such as Oracle Database server and Microsoft SQL Server. From an open source perspective these RDBMSs include MySQL, MariaDB, and PostgreSQL as the most commonly used open source RDBMS in production today.
The RDBMS that we used today rely on SQL as the engine that allows us to perform all the operations required to create, retrieve, update, and delete data as needed.

Eventually in 1986 SQL was adopted by ANSI and ISO standards organizations paving the way for Microsoft SQL Server and the various open source databases we have on the market today.

It was rapidly adopted as the basic query language for other relation database management systems, or RDBMS such as IBM’s DB2 and in 1979 Relational Software Inc.’s (now known as Oracle Software) Oracle V2 database server for Vax systems.

The usefulness of being able to access several records from a single command that does not require specifying how to reach a given record was immediately recognized by the computing world. SQL was created in the early 1970s at IBM as method of accessing IBM’s System R database system. The SQL database has long been the tried and true workhorse of the backend enterprise and at the heart of everything we do in this electronic age. It's used for relational databases. A SQL database is a collection of tables that stores a specific set of structured data. SQL stands for Structured Query Language. In this blog, we give a basic overview of what a SQL database is and compare a few of the most commonly used ones: MariaDB, MySQL, and PostgreSQL (sometimes referred to as Postgres). SQL databases have been used for decades - and they're still in use today.
