Understand the core components of the relational model in DBMS - relations, tuples, and attributes. Learn how data is structured in tables and why these elements matter in databases.- Published on
Learn what relationship attributes are in ER models, why they matter, and how to use them with clear examples like student enrollments and employee positions.- Published on
Learn what First Normal Form (1NF) is, why it's important in DBMS, and how to convert tables to 1NF using real-life examples.- Published on
Learn Armstrong's Axioms (Reflexivity, Augmentation, and Transitivity) used to derive all functional dependencies in a relational database. See how these rules help with normalization using simple examples.
