How do I master basic crud operations?

Connect to MySQL shell (`mysql -u root -p`) or Workbench. ```sql -- Create database CREATE DATABASE pets; USE pets; -- Create table CREATE TABLE cats ( id INT UNSIGNED NOT NULL AUTO_INCREMENT, name VARCHAR(150) NOT NULL, owner VARCHAR(150) NOT NULL, birth DATE NOT NULL, PRIMARY KEY (id) ); -- Insert data INSERT INTO cats (name, owner, birth) VALUES ('Sandy', 'Lennon', '2015-01-03'), ('Cookie', 'Casey', '2013-11-13'); -- Select data SELECT * FROM cats; SELECT name FROM cats WHERE owner = 'Casey'; -- Update UPDATE cats SET birth = '2014-11-13' WHERE name = 'Cookie'; -- Delete DELETE FROM cats WHERE name = 'Cookie'; ``` Practice in Workbench's SQL editor.

How do I conquer advanced queries?

Build on basics with filtering, aggregation, and joins. Follow [W3Schools MySQL Tutorial](https://www.w3schools.com/MySQL/) sections on SELECT, WHERE, JOINs. Examples: ```sql -- Aggregate SELECT owner, COUNT(*) as num_cats FROM cats GROUP BY owner HAVING COUNT(*) > 1; -- Join (create owners table first) CREATE TABLE owners (id INT PRIMARY KEY, name VARCHAR(150)); INSERT INTO owners VALUES (1, 'Casey'); SELECT c.name, o.name FROM cats c JOIN owners o ON c.owner_id = o.id; -- Subqueries, LIKE, BETWEEN SELECT * FROM cats WHERE name LIKE 'C%'; ``` Use online editor at W3Schools to test.

How do I design robust databases?

Learn schema design from [Official Tutorial](https://dev.mysql.com/doc/refman/8.0/en/tutorial.html) and W3Schools constraints. Key concepts: - **Data Types:** INT, VARCHAR, DATE. - **Constraints:** PRIMARY KEY, FOREIGN KEY, UNIQUE, NOT NULL. - **Indexes:** CREATE INDEX idx_name ON table(column); - **Normalization:** Avoid redundancy (1NF-3NF basics). Example with relationships: ```sql ALTER TABLE cats ADD COLUMN owner_id INT; ALTER TABLE cats ADD FOREIGN KEY (owner_id) REFERENCES owners(id); CREATE INDEX idx_owner ON cats(owner_id); ``` Model in Workbench EER diagram.

How do I build a project and advanced features?

Apply skills: Build a simple inventory DB. 1. Design tables: products (id, name, price), orders (id, product_id, qty). 2. Implement CRUD, JOIN queries for reports. 3. Add transactions: ```sql START TRANSACTION; ... COMMIT; ``` 4. Views: `CREATE VIEW order_summary AS SELECT ...;` 5. Backup: `mysqldump -u root -p pets > backup.sql` Explore [MySQL Reference Manual](https://dev.mysql.com/doc/refman/8.0/en/) for transactions, stored procedures. Test with sample data, query insights.
