Step 1: Describe in detail the exact operation of a library system. Your description will be used to create the entity relationship diagram in step 2.

Your library system must include the following: Books Members Authors Publishers Other entities can be included to compliment your solution. The appropriate attributes must be included for the above entities. Eg. Book ISBN Title Description Year etc The textual description of the system should capture the exact operation of the library and the relationships between the different entities.

Step 2: Create an entity relationship diagram based on your description of your library system. The diagram can be created using any ERD software you choose (eg: yEd https://www.yworks.com/products/yed). Submission: Your final submission should be in PDF format and include the ER diagram. The source file for your diagram also needs to be uploaded to Webcourses.
