DBMS vs RDBMS

 

DBMS

DBMS is defined as the software program that is used to manage all the databases that are stored on the network or system hard disk. There are different types of database management systems and some of them are configured for specific purposes.

DBMS is available in different forms as a tool that is used to manage databases. Some popular DBMS solutions include DB2, Oracle, FileMaker and Microsoft Access. Using these products, privileges or rights can be created that can be specific to particular users. It means that the administrators of the database can grant specific rights to some users or assign different levels of administration.

Every DBMS has some fundamental elements. First is the implementation of the modeling language which defines the language used for each database. Second, DBMS also administers the data structures. Data query language is the third element of a DBMS. Data structures work with data query language in order to make sure that irrelevant data cannot be entered into the database used in the system.

 

RDBMS

The database system in which the relationships among different tables are maintained is called Relational Database Management System. Both RDBMS and DBMS are used to store information in physical database.

RDBMS solution is required when large amounts of data are to be stored as well as maintained. A relational data model consists of indexes, keys, foreign keys, tables and their relationships with other tables. Relational DBMS enforces the rules even though foreign keys are support by both RDBMS and DBMS.

In 1970s, Edgar Frank Codd introduced the theory of relational database. Thirteen rules were defined by Codd for this relational theory or model. Relationships among different types of data Is the main requirement of the relational model.

RDMS can be termed as the next generation of database management system. DBMS is used as a base model in order to store data in a relational database system. However, complex business applications use RDBMS rather than DBMS.

 

 DBMS:

1)In dbms no relationship concept

2)It supports Single User only

3)It treats Data as Files internally

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

5)It requires low Software and Hardware Requirements.

6)FoxPro, IMS are Examples
RDBMS:
1)It is used to establish the relationship concept between two database objects, i.e, tables

2)It supports multiple users

3)It treats data as Tables internally

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

5)It requires High software and hardware requirements.

6)SQL-Server, Oracle are examples

 

 

DBMS

  • DBMS data is stored in the form of rows and columns
  • Data stored in dbms is temporarly
  • DBMS is DATA BASE MANAGEMENT SYSTEM
  • In DBMS keys are not used.
  • In DBMS duplication of rows ans columns.
  • In DBMS rows and columns are independent.
  • DBMS is for single user only.
  • DBMS does not satisfies codd’s rules.
  • Eg: DBMS: Sysbase foxpr

RDBMS

  • RDMS data stored in the form of tables
  • where as in rdbms is permanently
  • RDBMS is RELATIONAL DATABASE MANAGEMENT SYSTEM.
  • In RDBMS keys are used.
  • But in RDBMS there is no duplication of rows and columns.
  • But in RDBMS rows and columns are dependent.
  • RDBMS is for multi-user.
  • RDBMS satisfies codd’s rules.
  • Eg: RDBMS: Oracle, SQl  server

 

 

DBMS

RDBMS

DBMS data is stored in the form of rows and columns RDBMS data sotred in the form of tables
Data stored in dbms is temporary Where as in rdbms is permanently
DBMS is DATA BASE MANAGEMENT SYSTEM RDBMS is RELATIONAL DATA BASE MANAGEMENT SYSTEM.
In DBMS keys are not used In RDBMS keys are used.
In DBMS duplication in rows and columns. But in RDBMS there is no duplication of rows and columns.
In DBMS rows and columns are independent. But in RDBMS rows and columns are dependent.
DBMS is for single user only RDBMS is for multi- user
DBMS dose not satisfies codd’s rules. TDBMS satisfies codd’s rules.
Eg. DBMS: Sysbase foxpr Eg. RDBMS: Oracle, SQL server
