DBMS acronym for Database management system. There are number of DBMS like RDBMS, ORDBMS, HRDBMS etc . RDBMS is basically to define relationship between the tales and also it follows various codds rules.
RDBMS - Relational Database Management System - Multiple users can access and there will be relationships between the tables, security is increased
DBMS - Database Mangement system - small number of users
DBMS is the Database Engine itself
like MySql Server
RDBMS is the GUI (Graphical user interface)
for any Database Engine which used in
CRUD (Create, read, update and delete)
like PHPmyAdmin
Everything in this first answer (except the first sentence) is wrong.
A DBMS, is any system that manages databases, an RDBMS is a subtype of DBMS that is limited to what are called relationaldatabases. Relational databases must use 'relations' to connect data (a 'relation' might be 'contains' or 'owes-money-to' or any other relationship between two objects [rows in a table, or two or more tables]) as rows have no structure in an RDBMS - they have to be 'flat' unlike an 'object oriented' dbms which can 'nest' things (as you may be used to in object oriented programming languages. Check out 'relational algebra' to see some of the theory behind RDBMSs or even 'RDBMS' and 'SQL' on wikipedia for a better understanding of how they are actually used) P.S. nearly every DBMS is an RDBMS these days, check out apache's 'couchDB' for a non-relational (document-oriented) DBMS.
A DBMS (Database Management System) is software that manages a database. DBMSs may use different database models such as a relational database model (RDBMS). RDBMS (Relational Database Managment System) is a DBMS in which data is stored in tables and the relationships among the data is also stored in tables.

I am supposing that key means primary key.Superkey is any subset of attributes that uniquely identifies the tuples of a relation. This subset need not be minimal, that is, one can remove some attributes from it and it is still uniquely identifying. If all redundant attributes are removed you get a subset what is called primary key.

dbms stands for data base management system whereas rdbms is relational data base management system. A Database Management System (DBMS) is collection of software programs which enable large, structured sets of data to be stored, modified, extracted and manipulated in different ways. Whereas Relational Database Managemet System (RDBMS) is a data structured in database tables, fields and records. Each RDBMS tables consist of database table rows.
A DBMS (Database Management System) is a software that manages databases and provides functionalities to store, retrieve, and update data. An RDBMS (Relational Database Management System) is a type of DBMS that stores data in a structured way using tables with relationships between them. RDBMS enforces the relational model, which allows for data integrity through constraints and supports SQL for querying data.
A DBMS becomes an RDBMS when the data contained in its tables are related to one another by referential integrity rules. DBMS - Database Management System RDBMS - Relational Database Management System
A DBMS (Database Management System) is a software application that allows users to interact with a database. An RDBMS (Relational Database Management System) is a type of DBMS that organizes data into tables with rows and columns, and uses structured query language (SQL) for querying and managing data. RDBMSs are a subset of DBMSs, designed specifically for relational databases.
There are mainly three different Database architectures and they are network, hierarchical and Relational. The DBMSystems that follow the Relational architectural concepts are known as RDBMS. This is supposed to be superior in design and performance to the other two and there are, to my knowledge, no functional DBMS following the other two concepts in the market today.
A Data Base Management System (DBMS) is a generic term like tin of food. Microsoft Access (msaccess) is a relational database (RDBMS). There are also network, hierarchical, OLAP and other types of databases. So msaccess is a DBMS but not the other way around.
RDBMS is a Relational Data Base Management System Relational DBMS. This adds the additional condition that the system supports a tabular structure for the data, with enforced relationships between the tables. This excludes the databases that don't support a tabular structure or don't enforce relationships between tables.
A DBMS stores data in a table where the entries are filed under a specific category and are properly indexed. This allowed programmers to have a lot more structure when saving or retrieving data. A relational database contains data in more than one table. Each table contains a database that is then linked to other tables with respect to their relationships.
