Logically every single facts or figures about any information are data, information about anything and everything. We can store such facts or figures about information in notepad, word file, excel file, ms access, power point or in any other storage capabilities, we call them data store.
Relational database management system (RDBMS) is a set of components with capabilities to enable user to easy access, create and manage data using Structured Query Language (SQL).
In RDBMS you can Create, Read, Update and Delete data, check authentication and authorization for each user in very systematic way. SQL RDBMS has many built-in components and objects to carry out such activities. An RDBMS may also provide capability of displaying visual representation of the data.
Most of the well known Database applications fall into RDBMS category. Examples database like MySQL, Oracle Database,, Microsoft SQL Server, and IBM DB2 etc.
Any databases that are managed by other DMBS programs that support NoSQ, fall under Non-RDBMS category. Like Oracle NoSQL DB.
