For nearly 40 years, Relational Database Management Systems (RDBMS) have been known as the go-to option for the storage of information in databases, mainly for personal data, financial information, manufacturing records and more. The relational model for database management uses table format for storing data, which makes it different than the standard data management model. The popularity of RDBMS can be attributed to the increase in mission-critical applications over time which require a robust management system.
Today, all major relational databases use SQL as their query language. Although there is a standard SQL, most database platforms utilize different dialects that may include specific additional functions or a part of standard SQL abilities. In this article, we will introduce you to two major relational database management systems that are well received in the world of application development. We will draw a comparison between the features of these systems and help you choose the right RDBMS for your project. These RDBMSs are MySQL—the most popular and commonly used RDBMS, and PostgreSQL—the most advanced SQL compliant and open-source objective-RDBMS.
