Your professor desires to create a database that will be used to design custom built IS/Data Analysis courses. They want to know information about various text books and the topics that are covered within. They want to you to create an ERD to model the logic of the database that stores the information about the textbooks and the subjects that are covered (Course part of ERD/DB not required). The instructor feels that some subjects that they wish to cover may not have book chapters that are available. You may look at the table of contents for your textbook(s) for a general idea of the data. You should have at least 4 entities with at least one associative entity. You should list the foreign and primary keys in each entity. You should list at least 2 attributes for each entity and at least 5 for two of them. The relationships must have the cardinalities. You should list any assumptions that are made for the relationships.
