Database Systems and Data Modeling Fundamentals

Understanding how data is structured and stored is essential for building modern software applications and data workflows. This course guides you through the foundational principles of Database Management Systems (DBMS) and relational data modeling. You will learn how database models organize information, enforce structural integrity, and evaluate different system implementations. What you will learn: • Understand core DBMS concepts, architecture, and foundational terminology. • Design relational schemas using entity-relationship principles and appropriate data types. • Apply database normalization rules to eliminate redundancy and maintain data integrity. • Write foundational SQL queries to insert, retrieve, update, and filter structured records. • Explore modern data concepts including indexing strategies and NoSQL database paradigms. The material begins with clear definitions and core modeling concepts before progressing into relational schema design and query execution patterns through written explanations and code examples. This course is specifically written for absolute beginners and requires no prior programming or database experience.
