In this lecture of the databases course we learn about ISA inheritance in the entity-relationship model (ER model). This is also known as ISA specialization (or generalization). We will see that the ISA can be annotated with constraints disjoint (default is overlapping) and total specialization (every higher-level entity must belong to at least ...

Dr. Soper demonstrates how to create entity-relationship diagrams (ERDs) using Draw.io. Topics covered include creating entities and attributes, defining primary and foreign keys, marking attributes as required, creating and modifying relationship lines, changing cardinalities, creating weak entities, and marking relationships as non-identifying.

ER diagrams illustrate the logical structure of databases. An ER diagram is a means of visualizing how the information a system produces is related. There are five main components of an ERD: entities, actions, attributes, connecting lines, and cardinality.
