This Database Management Systems and SQL Full Course provides a structured learning path to understand how modern databases are designed, implemented, and managed. The course begins with an introduction to DBMS concepts, database users, system environments, and the history of database applications. Learners will explore DBMS architecture, three-schema architecture, and data independence to understand how databases are organized internally.
The course then focuses on data modeling using the Entity-Relationship (ER) model, covering entities, attributes, relationships, and the complete database design process. Students will learn the relational data model, characteristics of relations, relational constraints, and update operations. Core theoretical concepts such as relational algebra and query processing are explained through practical examples and exercises.
In the second part of the course, learners master Structured Query Language (SQL). Topics include DDL, DML, DCL, and TCL commands, constraints, primary and foreign keys, aggregate functions, grouping, filtering, joins, subqueries, and advanced SQL operators. The course also includes solved problems, quizzes, and hands-on practice to strengthen query-writing skills. By the end, learners will be able to design databases and write efficient SQL queries for real-world applications.
