Assignment 2
2. Develop use cases
By using user use goal technique

User goal and resulting use case

|
Potential patient
|
• Create account
• Schedule appointment
• View medication prescription
• View directions for taking medication
• View lab reports
• Send a message
|

doctors
|
• Make appointment schedule
• Make lab reports staff |

• Register current users

2.1 Using the Community Patient Portal System Part 1 and Community Patient Portal System Part 2 case study , create a list of all actors. Create a definition for each actor. Use the format "A (n) actorName is a ...." and then complete the sentence. For example, "A Student is a Person who is enrolled in a University." Place your actors and definitions in a table with 2 columns, one for Actor and the other for the definition.
An actor is an UML name for end users or also can be define as something that interacts with the system. The list of actors from the case study include
i. Patients
ii. Doctors
iii. Staffs
iv. HIPPA electronic health record system
A patient is a person who is seeking attendance in hospital
A doctor is a person attending to patients
A staff is an employee who assist on various operations
HIPPA is a system that keeps health records

2.2 Use the user goal technique and/or the event decomposition technique to create a list of use cases for each actor identified above. A use case can be used by more than one actor. Define/describe each use case. Place the use cases and descriptions in a table with 2 columns, one for the Use Case name and the other for the Description/Definition.

• View directions for taking medication
• View lab reports
• Send a message
• Refill prescription |

2.3 Using the CASE tool, draw a UML use case diagram following the notation conventions in your textbook and CASE tool.
A use case diagram is a UML diagram used to graphically show use cases and their relationship to actors
2.4 Use the event decomposition technique and create a list of use cases for each event. Name the event, state the type of event, and name and define the resulting use case.
An event is something that occurs that occurs at a specific time and place can be described and should be remembered by the system
Event decomposition is a type of use case technique that is more comprehensive

3. Develop a class diagram
3.1Using the two discussions for the CPPS case study and the noun analysis technique, identify potential classes from your noun analysis.
3.2 Create a table of the classes with the class name in one column and the definition in the other. For the definition, use the format "A (n) className is a ...." and then complete the sentence.
|
Class name
|
definition
|
|
patient
|
A patient is a person who creates account in the cpps system
|
|
account
|
An account is a registration created by patient
|
|
appointment
|
An appointment is a schedule created by patient
|
|
medication
|
A medication is a prescription by the doctor
|
|
labResult
|
A labResult is a report from a test
|
|
test
|
A test is a labResult that is detailed
|
|
report
|
A report is a test that is generates results
|
|
message
|
A message is a text that has recipient
|
3.3 Identify the relationships among the classes.
There is binary relationship or association between the classes where the multiplicity varies between different associations among the classes
Unary relationship is between labResult and test
3.4 Create a UML class diagram using the classes you have identified and add names to the associations and multiplicity constraints.
Class diagram is a UML diagram that shows classes with attributes and associations
Associations is a natural occurring relationship between classes
Multiplicity is term for the number of associations between classes: 1 to 1 or 1 to many
3.5 What are your impressions of the noun technique?
• It quickly help identify classes
• Ends up with a list of many nouns that cannot even be stored on the system
• It's a good start point for beginners when there is nobody to help in brainstorming
• It's a popular and much simpler technique
3.6 How can you use the CRUD technique to verify and validate your use cases?
CRUD stands for create, read/report, update and delete. You can use this technique to validate your use cases by following the following steps
• You must identify all the entities and domain classes involved in the new system
• You must verify that a use case has been identified that creates new instance, updates existing instance, reads or reports values of instances
• When a needed use case has been overlooked add a new use case and then identify the stakeholders
• Make sure it's clear which application is responsible for adding and maintain the data
