Q. Draw ER Diagram for an Online Book Store. Description: We want to build a system for online book store. In the online book store there should be all required information related to books, their authors, publishers and other attributes. The following information need to be depicted by the ER diagram. The books are written by authors and they are published by publishers. In the system, there should be the facility of shoping-basket/shopping cart where the customers can put their selected books. The books are stored in warehouse so we need to include the information of warehouse too. Identify the possible entities and their attribute, the relationships among the attributes and draw the E-R diagram for the above mentioned activities and associations. NOTE : take screen shot of your image
