Data is everywhere. The people who can query it, design it, & secure it are the ones getting hired.

This specialization takes you from zero SQL knowledge to job-ready skills.

Here’s what you will build skills in:

• SQL Foundations & Database Design

Set up MySQL, SQLite, and PostgreSQL on Windows and macOS, & design databases using ER diagrams and normalization from 1NF to BCNF, so your data is structured correctly from day one.

• SQL Querying, Joins & Data Manipulation

Filter and manipulate data across real tables using 6 JOIN types, subqueries, DML operations, aggregation functions, Views, and Indexes to retrieve exactly the data you need.

• Advanced SQL Programming & Automation

Build logic inside your database employing Stored Procedures, Triggers, and UDFs. Analyze data with Window Functions and CTEs, & control access by making use of GRANT & REVOKE.

• Real-World Projects, Security & Interview Preparation

Prevent SQL Injection, implement RBAC, build 5 complete database systems, & solve the exact interview patterns that data roles test for.
