LAB OVERVIEW The Expanded Entity Relationship Diagram

Scenario and Summary

This lab introduces the next step in creating a data model, the Entity Relationship Diagram (ERD). You will be given a business scenario for a University Medical Center, which is a small community hospital. The business specifications will outline a number of things about the business, some of which will apply directly to the database you are being asked to model. There is a table that lists the entities (tables) that will be needed for the database and related attributes (columns) for each entity. There is also a column that lists specific information about the entity that will be helpful in determining its relationship to other entities within the model.

Be sure to include the minimum and maximum occurrences of each relationship (cardinality) and to supply a name to the relationship that will work in both directions. Make sure to use Crow’s Feet notation in your ERD.

Narrative/Case Study

The University Medical Center is a small, community hospital. A new hospital administrator has recently been hired by the Board of Directors, and directed to right-size patient care and pharmacy services and improve profitability. The hospital operates three clinical facilities: the main hospital, a mid-town clinic, and an Urgent Care location. The hospital also offers selected in-home care services. Many of the patients are repeat or regular patients who receive regular treatment for various conditions, and many utilize the hospital’s pharmacy services for prescription medications.

The pharmacy dispenses about 3,000 different prescription medications of various kinds. Every prescription is associated with one patient, and is logged by the dispensing clinic. The new administrator wants to know which drugs are most prescribed, and also which are the most profitable.

The following is some general information about the organization and its current processes.

  • The hospital operates three clinical facilities.
  • A healthcare worker logs in at a facility at the start of a shift and logs out at the end.
  • The name, address, Social Security number and other information is recorded for every healthcare worker.
  • All healthcare workers have one billing rate, which is determined by their job description.
  • Each medication dispensed by prescription is linked to both the prescription number and the medication ID number, recording the item price and the quantity dispensed.

As a convenient and affordable means of providing hospice care, palliative care, and convalescent care to patients that need occasional/intermittent skilled nursing, but do not require hospitalization, the hospital offers limited in-home care. Recording of in-home care includes the healthcare worker ID, their departure time and return time, and also the prescription ID for any prescriptions administered by the healthcare worker in the home setting….
