- When working with database entity relationship modeling, should the cardinality between entities be translated/ read from both ends of the notation? In other words, should a relationship between entities have the ability to understood if read forwards and backwards?arrow_forwardCan the foreign key be extracted from another table that is not connected to it in entity relationship diagramarrow_forwardAccording to the data model, is it required that every entity instance in the PRODUCT table be associated with an entity instance in the CD table?

- Can you please help me in how I can turn the Entity Relationship diagram into a Logical Database Diagram? I know I need to list out all the entities, but I am not sure how to draw the relation. If you would please write it step by step for me so I can practice, that would be much appreciated.arrow_forwardPlease read this carefully and Draw an EER diagram for a database of a hospital following these requirements: create Four to five regular strong entities. A union One 1:1, one 1:N, and one N:M relationship – of which at least one relationship should be partial and one full. One overlap relationship and one disjoint relationship. Other notes: Do not emphasize on too many attributes for the entities. Two to three attributes for each entity will be enough. Make sure to include a primary key for each entity.arrow_forwardDescribe the concept of dimensional modeling in data warehousing.

- The course I'm taking is database management. I have attached the question. Please provide solution in detail so i can better understand why. Thank you in Advance!arrow_forwardThe purpose of the assignment is to facilitate the learning of data modeling concepts through models developed by individuals. Things to be considered in the applications to be developed: Creating a model with at least 15 tables for vaccination tracking system. The characteristics and relationships of the tables are in the model. Step by step analysis of the normalization steps for a table with multiple relationships in the model. It will briefly be stated which entity-tables will be used for what purpose. Only special rules will be added in the relational data model that cannot be directly specified.arrow_forwardExplain the concept of cardinality in data modeling and how it affects the relationships between entities.arrow_forward
