DBMS: DBMS Stands for Database mangment system
Database management systems (DBMSs) are the systems which were  specially designed in a way that it can interact with the user, other applications, and the database itself to capture and analyze data.
The various models of database management systems are:
1. Hierarchical
2. Network
3. Object-oriented
4. Associative
5. Column-Oriented
6. Navigational
7. Distributed
8. Real Time Relational
9. SQL

Earlier there were File System Databases which were not as efficient as the DBMS because multiple users cant work on FMS. There were no relation between the diffrent files. while with new dbms you can access the multiple objects
and store data accross multiple objects.The example of a flat file database is a basic name-and-address list, where the database consists of a small, fixed number of fields:Name, Address, and Phone Number. Another example is a simpleHTML table, consisting of rows and columns

RDBMS is a form of DBMS where RDBMS stands for Relational Database Management System in whihc data stores in form of table and these tables can have relations between them.Key are used to get relation between multiple system.RDBMS is proposed by codd.SQL Server, Oracle are the some of the RDBMS which are available.
