Entity-Relationship Diagrams (ER Diagrams) are visual tools used to design and represent the structure of a database. They illustrate how entities, such as tables or objects, relate to each other through defined relationships. This training explains core components like entities, attributes, primary keys, foreign keys, and relationship types such as one-to-one, one-to-many, and many-to-many. It also covers how ER diagrams help in database planning, normalization, and logical schema design. You will learn how to convert business requirements into structured database models using ER diagrams. The course also highlights best practices for designing clear, efficient, and scalable database architectures for real-world applications.
