What is DBMS? DBMS stands for Database Management System. It's a software that manages and stores data on your computer. This system organizes data in files and doesn't connect them, which can sometimes result in duplicate data and lower security.

What is RDBMS? RDBMS means Relational Database Management System. It's a type of DBMS that organizes data in tables which makes it easier to connect the data in different tables. It was developed in the 1970s by E.F Codd. Examples include SQL, MySQL, and Oracle. RDBMS helps handle large data sets effectively and supports complex queries, making it more efficient than traditional DBMS.

Key Differences:

DBMS stores data as files without relational connections, leading to potential duplications and lower security.
RDBMS stores data in table formats with relationships, which prevents data duplication and offers better security and speed because it supports indexing and normalization.

Examples of RDBMS:

Oracle Database: Known for its data management capabilities and advanced analytics.
MySQL: Popular for its simplicity and speed, commonly used in web applications.
SQL Server: Developed by Microsoft, known for its advanced security features and business intelligence tools.
PostgreSQL: A feature-rich open-source RDBMS known for its extensibility and compliance with industry standards, emphasizing data integrity and support for advanced SQL features.

Important Features of RDBMS:

Atomicity: Guarantees that all parts of a transaction are processed or none are.
Consistency: Ensures the database remains correct and reliable before and after transactions.
Isolation: Keeps transactions separate until they’re completed.
Durability: Once a transaction is committed, it will remain so, even in the event of a system failure.
