Getting Started with InfoSphere Data Architect

Chapter 4 – Domain Models 83
The domain data type is specified in the Data Type field of the SSN attribute.
4. Change the data type for the STUDENT ID attribute:
a. Open the Data Type tab of the Properties view.
b. Click the ellipsis (…) next to the Data Type field. The Select a Data Type
window opens.
c. Select the STUDENT_ID data type from the STUDENT_PII_ROOT package.
5. Save your work.
4.3 Exercise
Complete the STUDENT_PII_DOMAIN domain model.
1. Create the following atomic domain elements:
• EMAIL: The base type is VARCHAR(128). This is personally identifiable
information, and the privacy for this element is required. To mask the data, a
random email address should be used.
• LAST_NAME: The base type is VARCHAR(128). This is personally identifiable
information, and the privacy for this element is only a best practice. When
masking the data, use a random shuffle as the privacy policy.
2. Create the EMAIL ADDR attribute in the STUDENT entity, and associate the
EMAIL atomic domain element with that attribute.
3. Associate the LAST NAME attribute with the LAST NAME atomic domain.
4. Save your work.
4.4 Summary
This chapter summarized how to create a domain model within IBM InfoSphere Data
Architect. You learned how to associate this domain model with an existing logical data
model and to identify information that should be privatized when you or other teams are
testing your models and systems.
4.5 Review questions
1. What is the definition of a domain model?
2. What information is stored in a domain model?
3. True or false: Domain models help you identify the data privacy policies for your
enterprise.
4. True or False: You can define your own data types with a domain model.
