SQL Database Concepts:

#mysql #sql #python #database

💡 Sharing my key takeaways from today’s study session:

1️⃣ SQL vs NoSQL

SQL → Structured data, fixed schema, relational tables.

NoSQL → Unstructured/semi-structured data, flexible schema, handles big & dynamic data.

Use SQL when data is consistent & relational, NoSQL when data is large, scalable & diverse.

2️⃣ SQL vs MySQL

SQL → Language (Structured Query Language) used to manage & query relational databases.

MySQL → A Database Management System (RDBMS) that implements SQL.
👉 In short: SQL = Language | MySQL = Software using that language.

3️⃣ DBMS vs RDBMS

DBMS → Database system (stores data, no strict relationships). Example: MS Access.

RDBMS → DBMS + relationships between tables (uses keys, constraints). Example: MySQL, Oracle.
👉 RDBMS is an advanced form of DBMS.

4️⃣ Stored Procedures vs Functions

Stored Procedure → Set of SQL statements stored in DB, can return multiple values, used for business logic.

Function → Must return a single value, mainly used for computations.
👉 Procedure = multi-purpose, Function = calculation focused.

✅ Excited to keep learning & sharing more database concepts.
