WGU C792 Task 2: Entity Relationship Diagram (ERD) 2023

WGU C792 Task 2: Entity Relationship Diagram (ERD) 2023. What I've learned in this course is that data modeling makes it possible to store and retrieve data efficiently, and that it also reports the information that makes it possible to quickly retrieve data by selecting certain information. In a hospital database, for instance, we can view a patient's medical history with a single click, without having to open any additional files. Entity relationship diagrams like the one I made were possible because of my knowledge of how data are linked, which in turn makes for easy archiving and retrieval (ERD). For instance, a patient's name, Birthdate, and medical record number provide a three-part identifier in hospitals (MRN). In this scenario, patients, dates of birth, and medical record numbers are all aspects that interact to provide a unique identifier for each patient.
