Difference between DBMS and RDBMS
DBMS stands forDatabase Management System. A database is an organized collection of data. It is a collection of tables, queries, reports, views, and other objects. Database designers typically organize the data to model aspects of reality in a way that supports processes requiring information, such as (for example) modelling the availability of rooms in hotels in a way that supports finding a hotel with vacancies.
A database management system is a computer software application that interacts with end-users, other applications, and the database itself to capture and analyze data. A general-purpose database management system allows the definition, creation, querying, update, and administration of databases.
- Examples of DBMS are file system, XML, Windows Registry, MS Access, FoxPro etc.
A database is not generally portable across different DBMSs, but different DBMSs can interoperate by using standards such as SQL and ODBC or JDBC to allow a single application to work with more than one database management system. Computer scientists may classify database management systems according to the database models that they support; the most popular database systems since the 1980s have all supported the relational model – generally associated with the SQL language. Sometimes a DBMS is loosely referred to as a “database”. Though RDBMS is an extension of DBMS There are some differences between DBMS and RDBMS.
Differences between DBMS and RDBMS
DBMS uses the file system to store data, so there will be no relation between the tables. IBMS, data values are stored in the form of tables, so a relationship between these data values will be stored in the form of a table as well.
|DBMS stands for Database Management System.||RDBMS stands for Relational Database Management System.|
|DBMS applications store data as a file.||RDBMS applications store data in a tabular form.|
|In DBMS, data is generally stored in either a hierarchical form or a navigational form.||In RDBMS, the tables have an identifier called primary key and the data values are stored in the form of tables.|
|Normalization is not possible in DBMS.||Normalization is possible in RDBMS.|
|DBMS does not apply any security with regards to data manipulation.||RDBMS defines the integrity constraint for the purpose of ACID (Atomicity, Consistency, Isolation and Durability) property.|
|database management system has to provide some uniform methods to access the stored information.||RDBMS system supports a tabular structure of the data and a relationship between them to access the stored information.|
|DBMS does not support distributed database.||RDBMS supports distributed database.|
|DBMS is meant to be for small organization and deal with small data. it supports single user.||RDBMS is designed to handle a large amount of data. it supports multiple users.|
|Examples of DBMS are file systems, XML, Dbase, Microsoft Access FoxPro etc.||Examples of RDBMS are MySQL, PostgreSQL, SQL Server, Oracle, MariaDB, SQLite etc.|
