To process a prescription order, RPS needs to know about the patients, the nursing home, and the nursing home unit where each patient resides. Each nursing home has at least one, but possibly many, units. A patient is assigned to a specific unit. An order consists of one or more prescriptions, each for one specific drug and one specific patient. An order, therefore, consists of prescriptions for more than one patient. Careful tracking and record keeping is crucial. In addition, each patient has multiple prescriptions, and one pharmacist fills each order.
1.Based on the above information, create an entity-relationship diagram that shows the data storage requirements for the system using Visio or its open source alternative software. Add six (6) attributes to each data entity and show minimum and maximum cardinality. Note: The graphically depicted solution may not exceed one (1) page per diagram.
2.Then, create a domain model class for the same information using Visio or its open source alternative software. Include six (6) attributes for each class and show minimum and maximum multiplicity. Note: The graphically depicted solution may not exceed one (1) page per diagram.
There are several points in the order-fulfillment process at which information must be recorded in the system. Case manifests must be printed at the start of each shift. Because a prescription may take a long time to be used completely, information must be entered into the system each time a medication is sent, noting the quantity sent and which pharmacist filled the prescription for that shift.
Prescriptions contain basic information such as ID number, original date of order, drug, unit of dosage (pill, teaspoon, suppository), size of dosage, frequency of dosage, and special instructions
