Free Download Udemy - RDBMS & SQL - Fundamentals for Backend Developers Published: 3/2025 Created by: Koushik Kothagal MP4 | Video: h264, 1280x720 | Audio: AAC, 44.1 KHz, 2 Ch Level: Beginner | Genre: eLearning | Language: English | Duration: 31 Lectures ( 3h 20m ) | Size: 4 GB RDBMS & SQL mastery, joins, and transactions for secure data What you'll learn Grasp the relational model, ACID guarantees, and SQL's edge for data integrity. Install and configure MySQL, then practice with real-world data sets. Get hands-on with DDL, DML, DCL, and TCL for complete database control. Build robust tables, define keys, and handle diverse SQL data types. Use SELECT, INSERT, UPDATE, DELETE, and manage NULL values effectively. Master advanced clauses-GROUP BY, HAVING, ORDER BY-and harness subqueries. Link tables using joins (inner, outer) and foreign keys for data relationships. Optimize performance with indexes, EXPLAIN, and targeted query tuning. Secure databases via user permissions, parameterized queries, and safe passwords. Implement transactions, lock granularities, and rollback for fail-safe operations. Automate logic and enforce rules with triggers to streamline application logic. Leverage views, temporary tables, and derived queries for cleaner data retrieval. Requirements Basic programming knowledge (any language) Familiarity with the command line (optional but helpful) A computer with MySQL installed or the ability to install it Willingness to practice SQL commands regularly Description Are you preparing for a backend developer role or gearing up for a crucial technical interview? This comprehensive course will guide you through the world of Relational Database Management Systems (RDBMS) and Structured Query Language (SQL) from the ground up. You'll learn how to design scalable, secure databases and master fundamental SQL commands while exploring real-world use cases and hands-on exercises.From table creation and data manipulation to advanced topics like subqueries and joins, this course provides a structured approach that will help you confidently work with relational databases. You'll see how key components such as primary and foreign keys maintain data integrity, discover the power of transactions and locks for multi-user environments, and learn how to optimize queries with indexing and the EXPLAIN keyword to boost performance.By the end of this journey, you'll be able to build robust databases, write optimized queries, manage user privileges with Data Control Language (DCL), and implement secure best practices against common vulnerabilities. We'll also dig into triggers, views, and transaction control, giving you a complete toolbox for tackling complex data challenges in any production environment.Whether you're brushing up on SQL for an upcoming interview or looking to refine your backend development skill set, this course arms you with the practical knowledge and hands-on expertise to stand out. Join us and unlock the power of RDBMS and SQL for your projects and professional growth.
