You want to create a database about the books on your shelf. Each book has authors (only the last name is needed), title, publisher, courses used in (course number only). Draw the ER diagram using the Chen-like model, and then write the English description for your diagrams. Compare the English to your diagrams and state any assumptions you made when drawing the diagrams.
