FLComment "Sql" For resources
I made a pdf which has video tutorials for SQL and documentation for DBMS
Difference Between SQL and DBMS
DBMS (Database Management System) is software used to store, manage, and organize data. It provides tools to create databases, define structures (tables), control access, and maintain data efficiently. Example: MySQL, PostgreSQL, Oracle, SQL Server.
SQL (Structured Query Language) is the language used to communicate with a DBMS. It allows you to insert, update, delete, and retrieve data from the database. SQL is not software — it is a query language.
In simple terms:
DBMS = the system that stores data
SQL = the language used to talk to that system
Example:
MySQL (DBMS) stores your tables → you use SQL queries to fetch data from those tables.

EMComment “SQL” to get links!
🚀 Want to master SQL without getting bored to tears? This mini roadmap takes you from “what is a database?” to solving complex crimes with code.
🎨 DrawSQL
Stop trying to visualize complex databases in your head. This tool lets you build beautiful Entity Relationship Diagrams (ERDs) just by dragging and dropping. It is the best way to understand how tables relate to each other—Foreign Keys and Joins finally make sense when you can actually see them.
⚡ SQLBolt
Perfect if you want to learn by doing, not reading. This site gives you bite-sized, interactive lessons right in your browser. No installation needed. You’ll race through the basics of SELECT, filtering, and aggregations with instant feedback on your code.
🕵️ SQL Murder Mystery
The ultimate way to practice. There has been a murder in SQL City, and you have to solve it by querying the police database. You will use advanced logic, joins, and wildcards to find the killer. It turns “studying” into a detective game you actually want to play.
💡 With these resources you will:
Visualize database architecture like a System Designer
Master the syntax through hands-on repetition
Build real-world problem-solving skills (and have fun doing it)
If you are aiming for Data Analytics or Backend Engineering roles, these 3 tools are your cheat sheet.
📌 Save this post so you don’t lose the roadmap.

MA📘 Advanced DBMS – Functions (Handwritten Notes)
Database functions are a core part of Advanced DBMS 💾
They help in data processing, calculations, filtering, and reporting — and are very important for practicals, viva & exams.
📌 In these handwritten notes, you’ll learn:
✔ Aggregate functions (SUM, AVG, COUNT, MIN, MAX)
✔ Scalar functions
✔ String & Date functions
✔ Syntax + examples
✔ Exam-oriented queries
✍️ Notes are designed to be:
• Simple language
• Clean handwritten format
• Query-based explanation
• Quick revision friendly

👩💻 Steal my study plan for MongoDB
.
I taught myself MongoDB and I have used it to build a real world application. Here is the steps I would love to share with u how I learned it
.
🧩 Research the fundamentals of MongoDB:
NoSQL is different from SQL, it is important to understand the key-pair strategies in Mongodb, how to use collections, how to manipulate data
.
🧩 Learn to build small applications with CRUD (Create, Read, Update, Delete):
Build a small e-commerce store with MongoDB utilizing CRUD with strategies like $insert_one, $insert_many, $update_one, $update_many, $delete_one, $delete_many etc.
.
🧩 Learn about data modeling and schema design:
Learn the techniques in normalization and denormalization, when to embed documents, referencing
.
🧩 Learn about aggregation framework:
Once your database gets larger, you will need to understand the aggregation framework: Practice using aggregation strategies like $match, $group, $project, $lookup to perform complex queries.
.
🧩 Learn about scaling and security:
Learn to scale your database, and security such as authentication methods and user roles in MongoDB, and explore how to secure your MongoDB deployment.
.
🧩 Build real world application:
Now build a bigger application! Not just one, more. You can build the application in Python.
.
You don’t need to enroll in any courses, documentation is all you need! Don’t forget to google your questions.
.
👩💻I am a self taught software engineer turned startup founder, I learn machine learning during my free time and I am here to inspire you to self teaching programming

MOStarting TODAY… we’re officially kicking off my 30-Day SQL Bootcamp right here on Reels
simple SQL from scratch
Comment START for the resources
Here’s our roadmap 👇
✨ Week 1: We break down the basics — Data, DBMS, and getting your SQL software installed.
✨ Week 2: We master the backbone of every database: CRUD (Create, Read, Update, Delete).
✨ Week 3: We get smart with grouping, filtering, and aggregate functions that actually make sense.
✨ Week 4: We level up JOINS, UNIONS, SUBQUERIES — the things that make you feel like a real data analyst.
Whether you’re a student, a marketer, a freelancer, or someone planning a full pivot into analytics… this free series is your first real step into the backend world of the internet.
But listen… 👇
If you want the full data stack SQL to pull the data, Excel & Power BI to make it speak then you’re going to want this:
My Excel & Power BI Masterclass goes LIVE on December 14th.
A complete, hands-on cohort where you’ll learn to build clean, professional dashboards that impress managers and convert clients.
If you’re serious about stepping into Business Intelligence…
DM me “DATA” to reserve your spot for the Dec 14th batch. Spots are going quickly.
Turn on notifications because Day 1 drops in the next Reel and you don’t want to miss the start.
