What is RDBMS?
A Relational Database Management System (RDBMS) is like a computer program that helps people store and organize data in a structured way. It’s like a digital filing system for information.
Advantages of RDBMS:
- Structured Data: RDBMS helps organize data into tables with rows and columns, making it easy to understand and manage.
- Data Integrity: It ensures data accuracy by using rules (constraints) to prevent wrong or incomplete data from being stored.
- Relationships: RDBMS can link data from different tables, helping to avoid duplication and improving data consistency.
- Query Language: It provides a simple way to ask questions and retrieve specific data using a language called SQL.
- Security: RDBMS offers access controls to protect data from unauthorized users.
- Scalability: You can add more data without major changes to the structure, making it suitable for growing businesses.
- ACID Properties: RDBMS ensures data transactions are reliable, even in case of system failures.
Disadvantages of RDBMS:
- Complexity: Setting up and maintaining an RDBMS can be complicated and costly.
- Scalability Limits: While it’s scalable, there are limits to how much data it can handle efficiently.
- Performance Issues: Handling very large datasets or complex queries can sometimes lead to slower performance.
- Not Ideal for Unstructured Data: RDBMS is not well-suited for storing unstructured data like images or videos.
- Cost: Licensing and hardware costs can be high, which might be a challenge for small businesses.
- Not Always the Best Choice: In some cases, other database types like NoSQL databases may be a better fit depending on the data needs.
