What is Database ? Difference between
DBMS and RDBMS
 A database is a collection of information that is organised so that it can be easily accessed, managed and updated.
- It can be accessed or stored at the computer system. It can be managed through Database management system (DBMS).
- It refers to related data, which is in a structured form.
- It contain several tables, which may each include several fields/values.
- For example all e-commerce or dynamic websites uses databases to store product inventory and customer information.
- By storing website data in a database, the data can be easily searched, sorted, and updated.
Most popular types of database :
-
- Flat
- Relational database management systems
- Dimensional
- NoSQL and object-oriented database
What is DBMS?
-
- DBMS is a collection of programs for managing data and simultaneously it supports different types of users to create, manage, retrieve, update and store information.
- This essentially serves as an interface between databases and end users or application programs, ensuring that data is consistently organized and remains easily accessible.
- For example, from a small startup firm to the multinational companies , managing a huge amount of data becomes a difficult task. hence , the software like the DBMS brought a revolution in many fields regarding efficient information management.
Components of a DBMS?
-
-
- Storage engine.
- Metadata catalog
- Database access language
- Optimization engine
- Log manager
- Data utilities
-
What is RDBMS?
-
- The standard for relational database management systems (RDBMS)
- A database management system that manages data as a collection of tables in which all relationships are represented by common values in related tables.
- Data in RDBMS is stored and sorted in the form of rows, columns (also called tuples and attribute in the DBMS language).
Difference between DBMS and RDBMS
DBMS | RDBMS |
Data stored as a file. | Data is stored in the form of tables. |
DBMS supports a single user. | RDBMS supports multiple users. |
Data stores either in either a navigational or hierarchical form. | RDBMS uses tabular structures to store data, headers are the column names and the rows contains values. |
The database does not support normalisation. | It supports the normalisation and joining of tables. |
Does not support a distributed database. | Supports a distributed database. |
Does not support client-server architecture. | Support client-server architecture. |
No relationship between the data value | Data relationship with the help of foreign keys |
Low software and hardware | High software and specialised DB hardware |
DBMS was not made to handle a huge amount of data. | RDBMS can actually handle a very high amount of data. |
Lack of security in the DBMS model of storing data, | More security of the data stored as several log files created |
Example-XML,file system, etc. | Example- MYSQL, Oracle, SQL Server, etc |
