I’m working on a databases project and need an explanation to help me learn.ScenarioA small surgery center needs your help to create a database. The office manager has identified the following types of data (entities): patients, doctors, procedures and appointments using the following business rules: Patients can have many doctors and many doctors can see many patients.
Patients can have many procedures and many procedures are done on patients.
Doctors can have multiple appointments. (hint: these are many to many relationships, so associative tables need to be added).
Requirements Please identify the attributes and primary keys needed for each of the entities.
Identify the data types you would use for each of the attributes.
Determine the relationships between the entities and find the one-to-many and many-to-many relationships.
Create an ER diagram using Visio include the associative tables based on your analysis.
Identify all foreign keys needed in the database design.
