Udemy – RDBMS & SQL: Fundamentals for Backend Developers 2025-3

RDBMS & SQL: Fundamentals for Backend Developers. This comprehensive course is designed for backend developers and those preparing for technical interviews. Participants will learn from the ground up about relational database management systems (RDBMS) and Structured Query Language (SQL). They will learn how to design scalable and secure databases, and will master fundamental SQL commands, along with real-world use cases and hands-on exercises. This course provides a structured approach that helps learners confidently work with relational databases, from creating tables and manipulating data to advanced topics such as subqueries and joins. They will understand how key components such as primary and foreign keys maintain data integrity, and they will explore the power of transactions and locking for multi-user environments. They also learn how to optimize queries with indexing and the EXPLAIN keyword to increase performance.

By the end of this course, learners will be able to build robust databases, write optimized queries, manage user privileges with the Data Control Language (DCL), and implement security best practices against common vulnerabilities. Triggers, views, and transaction control are also covered, providing learners with a complete toolkit to tackle complex data challenges in any production environment. With its practical knowledge and applied expertise, this course will prepare participants to stand out, whether reviewing SQL for an upcoming interview or enhancing their back-end development skill set. By joining this course, learners will unlock the power of RDBMS and SQL for their projects and professional growth.

What you will learn

Will understand the relational model, ACID guarantees, and the advantage of SQL for data integrity.
It will install and configure MySQL, then practice with real datasets.
It will work practically with DDL, DML, DCL and TCL for complete database control.
It will create robust tables, define keys, and handle various SQL data types.
It uses SELECT, INSERT, UPDATE, DELETE and will handle NULL values effectively.
You will master advanced clauses — GROUP BY, HAVING, ORDER BY — and the use of subqueries.
It will link tables using joins (internal, external) and foreign keys for data relationships.
It will optimize performance with indexes, EXPLAIN, and targeted query tuning.
It will secure databases through user permissions, parameterized queries, and secure passwords.
It will implement transactions, fine-grained locking, and rollback for fail-safe operations.
It automates logic and enforces rules with triggers to simplify application logic.
It will use views, temporary tables, and derived queries to retrieve cleaner data.

This course is suitable for people who:

Aspiring backend developers looking for a strong foundation in databases.
Programmers preparing for interviews that test SQL and RDBMS concepts.
Computer science students looking for hands-on SQL practice.
Professionals looking to improve or refresh their skills in SQL and database design.
