RDBMS, DBSS, and DBMS are all acronyms that refer to different types of database management systems. An RDBMS (Relational Database Management System) is a type of database management system that is based on the relational model, which organizes data into tables with rows and columns. A DBSS (Database System Software) is a software system that provides the mechanisms needed to create and manage a database, such as data storage, data manipulation, and data security. A DBMS (Database Management System) is a more general term that refers to any software system that is used to create and manage a database.
These types of database management systems are still widely used today, especially in large organizations and businesses where there is a need to store and manage large amounts of data. They are still relevant because they provide a structured and organized way to store and manage data, allowing users to easily access and manipulate data in a variety of ways. In comparison to VHS and Betamax video tapes, which are no longer widely used due to the advent of newer technologies, RDBMS, DBSS, and DBMS are still in widespread use because they continue to provide valuable functionality for managing and organizing data.
