In this world where everything is becoming so digital; we need to store data in a precise manner which can be fetched easily and conveniently at the time of the request. This is where the database in computers came into existence. So, in this post, we will get to know about what the database is, what its types are and what the difference between dbms and rdbms is.
What is a Database?
The database is a systematic collection of data which supports storage and manipulation of data. The databases are used to make the data management easy. They are becoming more and more popular as per the usage in modern times.
What is DBMS?
It is software which is used to store and manage data. It was introduced to make the data storing easier which includes functions like insertion, deletion, and updating of the data. Other functions like defining, creating, revising and controlling the database are also the part of the package. It is specially designed for the individual business application to get the data.
What is RDBMS?
Relational Database Management System (RDBMS) is nothing but an advanced version of the DBMS system. It allows accessing data more efficiently then DBMS. The difference is that RDBMS is a software system which is stored in the form of tables.
What are the key differences between DBMS and RDBMS?
- DBMS stands for Database Management System while RDBMS stands for Relational Database Management System.
- The data is stored as a file in DBMS while the data is stored in tabular form in RDBMS.
- Normalization is present in DBMS while there is no normalization is present in RDBMS.
- Data is generally stored in either a hierarchical form or a navigational form while on the other hand, tables come as an identifier called as the primary key and tabular form is used to store data here.
- There no relation between the tables in DBMS, but in RDBMS data is used to store in form of tables, so the relationship is established.
- DBMS comes with the usage for the small organization and deal with small data, it supports the single user. In RDBMS, the application is designed for the multiple users, so RDBMS is designed to handle a large amount of data.
- DBMS usually satisfies less than 7 rules of Dr. e.f code while if we go to the RDBMS, it usually satisfies more than 7 to 8 rules of Dr. e.f code.
- Distributed Database is supported in DBMS, while it is not supported in RDBMS.
- In DBMS, there are some uniform methods which is given to access the stored information. While in RDBMS, due to the tabular structure, the data and a relationship between them to access the stored information.
- File systems, XML etc. are some examples of DBMS. Mysql, Postgres, SQL server, oracle etc. are some examples of RDBMS.
So, these were some of the main differences between different types of database systems.
