HIM 650 Topic 2 DQ 2
Patients in hospitals usually recieve medications from a doctor. There is a 1-to-many relationship between patient and order. The same for order and medication, you can have several orders
Based on the information given and understanding of the medical field, we identified each entity. In addition, we created an ERD which contains 1 to many relationships that ensure our customers receive the best service.
How would the ERD be different? Do some of you have more entities than others?
Explain why the ERD you created is stronger and more precise than that of your classmate’s ERD.
you must include the following in your written response.
“How to build a computer – The first step to building a computer is acquiring the parts. This guide will start with a quick explanation of essential parts and elaborate on them further on. A computer is made up of a case (or chassis) which houses several important internal components, and provides places to connect the external components, including non-peripherals.”
Just because we have common ancestors does not mean that cloning and genetic engineering is a good idea – in fact, I could argue that it is a terrible thing that should be outlawed
to be or not to be.
Typically, a patient staying in a hospital receives medications that have been ordered by a particular doctor. Because the patient often receives several medications per day, there is a 1:M relationship between patient and order. Similarly,each order can include several medications, creating a 1:M relationship between order and medication.
Identify different entities from this scenario.
Create an entity-relationship diagram illustrating 1:1 and 1: many relationships.
