[DOCS] Add documentation for DBMS subject

[pushkarscripts]

Feature Description

Add structured and beginner-friendly documentation/resources for Database Management Systems (DBMS).

Problem It Solves

The platform currently has limited content for DBMS. Adding proper documentation would help students access organized learning material in one place.

Proposed Solution

Contributors can add:

• module-wise notes
• important concepts
• examples
• interview questions
• diagrams/tables where useful

Please maintain:

• proper markdown formatting
• beginner-friendly explanations
• consistency with existing documentation structure

Avoid copy-pasted or AI-dumped content without proper review and formatting.

Additional Context

Possible topics include:

• ER Models
• Normalization
• SQL Basics
• Transactions
• Indexing
• Joins
• ACID Properties

Hello @pushkarscripts,

I’d like to work on this issue.

I can create structured, beginner-friendly DBMS documentation covering module-wise concepts, examples, diagrams, interview questions, and properly formatted markdown while maintaining consistency with the project’s documentation standards.

I’ll ensure the content is clear, high-quality, and organized for effective learning and smooth review.

Sounds good.

Please make sure the documentation remains:

• beginner-friendly
• properly structured
• well formatted
• and consistent with the existing documentation style of the platform

Also avoid submitting the entire subject in a single huge PR. Smaller and focused PRs would be preferred for easier review and collaboration.

You can start working on this from the coding period onwards (15th May as per GSSoC guidelines). I'll assign the issue to you.
