- Install a DBMS of your choice and a SQL client if needed.

📌Day 2: Basic SQL Queries
- Learn the basic SQL syntax for querying data using SELECT statements.
- Practice retrieving data from a single table.
- Understand the WHERE clause for filtering data.

📌Day 3: Advanced SQL Queries
- Explore more complex queries with JOIN operations to combine data from multiple tables.
- Learn about GROUP BY and aggregate functions like COUNT, SUM, AVG.
- Practice sorting data with ORDER BY.

📌Day 4: Data Modification
- Study how to insert, update, and delete data using SQL.
- Understand the importance of transactions and how to use them.

📌Day 5: Database Design
- Learn the fundamentals of database design, including tables, columns, and data types.
- Explore normalization concepts to ensure data integrity.

📌Day 6: Advanced SQL Topics
- Dive into subqueries and derived tables.
- Study SQL views, indexes, and stored procedures.
- Familiarize yourself with common SQL functions like DATE and STRING functions.

📌Day 7: Practice and Review

💥Top 10 most asked SQL Therory Questions 🚀

SQL and Its Purpose:
SQL (Structured Query Language) is like the maestro of databases, orchestrating data management with its programming prowess. 🎶 Its primary gig? Interacting with databases for data retrieval, updates, and overall data magic.

2. SQL vs. NoSQL:
SQL databases are the neat freaks with structured schemas, while NoSQL databases are the free spirits, embracing unstructured data. SQL loves tables, NoSQL swings with documents, key-values, wide columns, and even graphs. 🔄

3. Database and Types:
Picture a database as a well-organized data party. There's SQL, NoSQL, object-oriented, and more, each bringing its own flavor to the gathering. 🎉

4. DBMS:
DBMS, the unsung hero in the data realm, manages databases, offering a smooth interface for users and applications to mingle with the data dance floor. 💃🕺

5. SQL Comments:
In SQL, comments play the backstage role. Single-line comments go '—', while multi-line comments prefer the '/* */' style. 🎭

6. SQL Joins:
SQL Joins? Think of them as the matchmakers, combining rows from different tables. INNER JOIN, LEFT JOIN, RIGHT JOIN, and FULL OUTER JOIN—each with its own matchmaking style. 💑

7. Join Differences:
INNER JOIN, the matchmaker, LEFT JOIN brings all from the left and matching from the right, RIGHT JOIN does the opposite, and FULL OUTER JOIN invites everyone to the party. 🎉💔

8. GROUP BY Clause:
GROUP BY is the organizer, grouping rows based on a column. SELECT department, AVG(salary) FROM employees GROUP BY department;—the VIP section of SQL. 🏰👑

9. HAVING Clause:
HAVING is the bouncer, filtering results of aggregate functions in a GROUP BY query based on a condition. Strict, but fair. 🚷

10. Aggregate Function Query:
Example query for the average, sum, and count: SELECT AVG(column), SUM(column), COUNT(column) FROM table;—where SQL becomes the maestro again, conducting data symphonies. 🎻📊
