Today, an experienced professional with 15+ years shared his ideas.
A Powerful Lesson I Hold On:
"A mentor once gave me advice that changed how I learn:
‘If you want to understand any technology, don’t just memorize it. Keep asking WHY. Ask WHY at least five times — that’s how you really understand.’"
"Now, whenever I learn a new concept in technology, I don’t just memorize it. I ask myself:
What problem does this solve?
Why not use another option?
How does it actually work?
Where is it used in real projects?
How will learning this help my career?
Each ‘WHY’ takes me deeper, helping me move from just remembering to truly understanding."
How to database work on WhatsApp: *You send a message: The message is encrypted on your phone. It goes to WhatsApp’s server only temporarily. The server delivers it to the receiver. Once delivered, the server deletes it (if undelivered, it stays up to 30 days).
When to use Database, SQL, MySQL, Oracle, PostgreSQL, RDBMS, DBMS, and ORDBMS, and what each one is useful for.
Database
A place to store and organize data (like a digital cupboard for information).
🔹 SQL (Structured Query Language)
A language used to talk to databases — to store, search, update, and manage data.
🔹 MySQL
A popular open-source database system that uses SQL. Often used in websites and apps.
🔹 Oracle
A powerful commercial database made by Oracle company, used in big enterprises.
🔹 PostgreSQL (Postgres)
An advanced open-source database known for handling complex data and being very reliable.
🔹 DBMS (Database Management System)
Software that stores and manages data in a structured way. Example: MS Access.
🔹 RDBMS (Relational Database Management System)
A type of DBMS where data is kept in tables with rows and columns. Examples: MySQL, Oracle, PostgreSQL.
🔹 ORDBMS (Object-Relational Database Management System)
An advanced type of RDBMS that can also handle objects (like in programming). Example: PostgreSQL.
Real-life examples of how to use List, Set, and Tuple in Python.
| Feature | List | Set | Tuple |
|---|---|---|---|
| Order | Ordered | Unordered | Ordered |
| Changeable | Yes (mutable) | Partly (add/remove only) | No (immutable) |
| Duplicates | Allowed | Not allowed | Allowed |
| Use Case | Flexible data | Unique items only | Fixed data |
This simple practice is transforming the way I learn and grow in technology.
I’m truly thankful for this life-changing advice
This session gave me confidence and a clearer perspective on applying technical concepts.
I realized that insights from experienced professionals make learning practical, easier, and long-lasting.
Motivated to keep pushing myself to learn every day.
