What is the difference between DBMS and RDBMS?

Question

After reading some answers on different websites I am confused now. So, it would be helpful to mention the key difference between DBMS and RDBMS and any relation between the

Answer 1

DBMS : Data Base Management System ..... for storage of data and efficient retrieval of data. Eg: Foxpro

1)A DBMS has to be persistent (it should be accessible when the program created the data donot exist or even the application that created the data restarted).

2) DBMS has to provide some uniform methods independent of a specific application for accessing the information that is stored.

3)DBMS does not impose any constraints or security with regard to data manipulation. It is user or the programmer responsibility to ensure the ACID PROPERTY of the database

4)In DBMS Normalization process will not be present

5)In dbms no relationship concept

6)It supports Single User only

7)It treats Data as Files internally

8)It supports 3 rules of E.F.CODD out off 12 rules

9)It requires low Software and Hardware Requirements.

FoxPro, IMS are Examples

RDBMS: Relational Data Base Management System

.....the database which is used by relations(tables) to acquire information retrieval Eg: oracle, SQL..,

1)RDBMS is based on relational model, in which data is represented in the form of relations, with enforced relationships between the tables.

2)RDBMS defines the integrity constraint for the purpose of holding ACID PROPERTY.

3)In RDBMS, normalization process will be present to check the database table cosistency

4)RDBMS helps in recovery of the database in case of loss of data

5)It is used to establish the relationship concept between two database objects, i.e, tables

6)It supports multiple users

7)It treats data as Tables internally

8)It supports minimum 6 rules of E.F.CODD

9)It requires High software and hardware

Answer 2

DBMS: is a software system that allows Defining, Creation, Querying, Update, and Administration of data stored in data files.

Features:

• Normal book keeping system, Flat files, MS Excel, FoxPRO, XML, etc.
• Less or No provision for: Constraints, Security, ACID rules, users, etc.

RDBMS: is a DBMS that is based on Relational model that stores data in tabular form.

• SQL Server, Sybase, Oracle, MySQL, IBM DB2, MS Access, etc.

Features:

• Database, with Tables having relations maintained by FK
• DDL, DML
• Data Integrity & ACID rules
• Multiple User Access
• Backup & Restore
• Database Administration

Answer 3

DBMS stands for "Database Management Systems" it includes all Databases. RDBMS are a special Type of DMBS . R in RDBMS implies that the database uses the Relational model. a collection of related tables in the relational model makes up a database.DBMS is used for simple and small application while RDBMS is used for applications with a huge database.DBMS are for smaller organizations where security is not concerned(i.e. DBMS does not impose any constraints) while RDBMS is quitely opposite( RDBMS define the integrity constraint for the purpose of holding ACID PROPERTY).
