What is Relational Database and How It Works in Tamil

A relational database is like a giant digital filing cabinet. Instead of papers, it stores data in tables. Each table is like a sheet in your organizer, holding specific types of information. The magic happens when these tables are connected, allowing you to link related data together.
Why This is Useful:
Efficient Data Management:
Instead of repeating author information for each book in the "Books" table, we reference the author's details in the "Authors" table using the AuthorID. This saves space and ensures consistency.
Easy Updates:
If an author's name changes or needs an update, you only need to do it in one place-the "Authors" table. The changes automatically reflect in all related books.
Reduced Redundancy:
Information is not duplicated. For instance, J.K. Rowling's name is stored once in the "Authors" table, and the reference (AuthorID) is used in the "Books" table.
Simplified Queries:
Want to find all books by a specific author? With the relationship established through AuthorID, you can easily query both tables to get the desired result.
Example Query:
SELECT Books.Title, Authors.AuthorName
FROM Books
JOIN Authors ON Books.AuthorID = Authors.AuthorID;
There are several relational database management systems (RDBMS) in the market.
#MySQL
An open-source relational database management system. It's known for its reliability, ease of use, and strong community support. MySQL is commonly used for web applications.
#PostgreSQL
Another powerful open-source RDBMS with a focus on extensibility and standards compliance. PostgreSQL is known for its support for complex queries and transactions.
#Oracle Database
A commercial database management system developed by Oracle Corporation. It's known for its robustness, scalability, and advanced features. Oracle Database is widely used in enterprise applications.
#Microsoft SQL Server:
A relational database management system developed by Microsoft. It integrates well with Microsoft's ecosystem and is commonly used in conjunction with .NET applications and Microsoft products.
,
#SQLite
A lightweight, embedded relational database engine. It's often used in mobile apps, embedded systems, and as a local database for desktop applications.
#MariaDB
A fork of MySQL, led by the original developers of MySQL after concerns about the acquisition of MySQL by Oracle. MariaDB aims to maintain open-source freedom and be highly compatible with MySQL.
#Amazon Aurora

[@unknowninformation827]

Super explanation bro, pls continue to explain more concepts in sql like schema,grant access

[@IT-with-vijay]

Thanks a lot for your positive feedback I'm thrilled that you found the explanation helpful. Absolutely, diving into concepts like schemas and granting access in SQL is a fantastic idea. These topics are crucial for understanding how databases are structured and how security and permissions are managed. I'll make sure to cover those in detail in an upcoming video. Stay tuned and feel free to drop any specific topics you'd like me to cover. Happy learning💡📚
