- Research snow-flake and star schema pros and cons. Which has less normalization?Derive relations from conceptual model to logical data model. Identify the PK and FK.Would you look if i got ER diagram right ? I am asked to design a conceptual data model using ER /EER diagramming for the business functions of a group of dental offices from the natural language description given below. Be sure to consider the cardinality of, and participation in, each relationship. Also, be sure to identify all key attributes. Document any assumptions you make due to the imprecise nature of the problem specification. "Each office employs one or more dentists, hygienists, and receptionists each of whom have an employee number. Patients are free to use any dental office but, naturally, must make appointments in advance. A record of all such appointments is kept which specifies the patient’s name, the date and time of the appointment and a list of services performed. Adult patients have a SIN (Social Insurance Number) but their children typically do not. Each office provides specific services (e.g. cleaning, filling, X-rays, extraction, etc.) to the patients and bills…
